1 00:00:01,240 --> 00:00:05,575 NARRATOR: A 17-year-old girl has been killed in a park. 2 00:00:05,600 --> 00:00:08,495 just panic, chaos, fear, terror. 3 00:00:08,520 --> 00:00:10,575 It's just a scene of mayhem. 4 00:00:10,600 --> 00:00:14,335 You just didn't expect that to happen to any of them. 5 00:00:14,360 --> 00:00:17,015 The community demands answers. 6 00:00:17,040 --> 00:00:19,215 justice for Jodie! 7 00:00:19,240 --> 00:00:21,895 With their prime respect on the run... 8 00:00:21,920 --> 00:00:24,375 We need to find these people. They're dangerous. 9 00:00:24,400 --> 00:00:26,655 Oh, he's through the conservatory. 10 00:00:26,680 --> 00:00:27,935 Police officers! 11 00:00:27,960 --> 00:00:30,135 ...police need to act fast. 12 00:00:30,160 --> 00:00:32,575 We will never give up because we need to find 13 00:00:32,600 --> 00:00:34,335 a trace of the killer at the crime scene. 14 00:01:20,560 --> 00:01:24,335 A Friday night in East London. Police are called 15 00:01:24,360 --> 00:01:26,535 to a stabbing in a children's play park. 16 00:01:26,560 --> 00:01:31,015 Scenes of just panic, chaos, fear, terror. 17 00:01:31,040 --> 00:01:32,455 You don't know what to do. 18 00:01:32,480 --> 00:01:35,255 I mean, no-one would know what to do, I think, in that situation. 19 00:01:35,280 --> 00:01:38,775 People have just witnessed their friend being brutally attacked, 20 00:01:38,800 --> 00:01:41,815 in an area where this kind of thing just doesn't happen. 21 00:01:41,840 --> 00:01:43,015 If you get it wrong, 22 00:01:43,040 --> 00:01:44,895 if you don't do your job properly there, 23 00:01:44,920 --> 00:01:49,175 someone could quite easily walk away from committing a serious crime. 24 00:01:49,200 --> 00:01:51,535 Friends tell police the teenager was sitting on a bench 25 00:01:51,560 --> 00:01:54,375 when she was attacked from behind. 26 00:01:54,400 --> 00:01:58,375 They identify her as 17-year-oldjodie Chesney. 27 00:01:58,400 --> 00:02:00,055 As much as it's a crime scene, 28 00:02:00,080 --> 00:02:03,295 the first priority is we need to save jodie's life. 29 00:02:03,320 --> 00:02:05,695 Jodie is blue-lighted to hospital. 30 00:02:05,720 --> 00:02:09,015 Those first office on the scene are as important as the detectives, 31 00:02:09,040 --> 00:02:12,415 so the questions they will be asking - who saw what happened, 32 00:02:12,440 --> 00:02:14,215 why has Jodie been stabbed? 33 00:02:14,240 --> 00:02:16,615 Jodie isn't the sort of person that I would be expecting 34 00:02:16,640 --> 00:02:19,815 as a police officer to come along and try and save their life. 35 00:02:21,160 --> 00:02:24,215 That is that when the forensic teams are called in. 36 00:02:24,240 --> 00:02:29,495 Crime scene manager Sarah Thirkell has investigated over 500 deaths. 37 00:02:29,520 --> 00:02:31,975 As a mother, I find it quite disturbing sometimes, 38 00:02:32,000 --> 00:02:34,975 going to scenes where young children are involved, 39 00:02:35,000 --> 00:02:37,375 especially if they're the same age as my children. 40 00:02:37,400 --> 00:02:39,455 From a forensic point of view, 41 00:02:39,480 --> 00:02:42,015 this is one of the worst scenes that you could attend. 42 00:02:42,040 --> 00:02:44,055 It's just a scene of mayhem. 43 00:02:44,080 --> 00:02:46,815 When you turn up at a scene and it's night time, 44 00:02:46,840 --> 00:02:49,055 there's a definite different feel to it. 45 00:02:49,080 --> 00:02:50,935 The simple fact you can't see everything, 46 00:02:50,960 --> 00:02:52,455 you could be walking in blood, 47 00:02:52,480 --> 00:02:56,095 there could be a knife just six yards away that you can't see. 48 00:02:56,120 --> 00:02:59,295 This is a violent situation, are the offenders still around? 49 00:02:59,320 --> 00:03:01,975 Quickly, it will be, secure that crime scene. 50 00:03:02,000 --> 00:03:06,215 It's very difficult to ascertain the actual size of the scene. 51 00:03:06,240 --> 00:03:08,535 In a park that's basically open all the way round, 52 00:03:08,560 --> 00:03:10,975 it can be really difficult to try and work out 53 00:03:11,000 --> 00:03:13,015 where the offenders have come in and exited, 54 00:03:13,040 --> 00:03:17,015 so it's really important that all entrance ancl exits are closed off 55 00:03:17,040 --> 00:03:20,455 so we can do a full, extensive search of the whole area. 56 00:03:20,480 --> 00:03:23,295 Because it's not just the area where the attack's happened, 57 00:03:23,320 --> 00:03:25,695 there might be some footprints further away from the scene 58 00:03:25,720 --> 00:03:27,695 that we will need to recover. 59 00:03:27,720 --> 00:03:29,775 ls there anything at that scene 60 00:03:29,800 --> 00:03:32,055 that would be able to indicate who it was that attacked her? 61 00:03:32,080 --> 00:03:35,735 The crime scene investigators will spend time 62 00:03:35,760 --> 00:03:38,655 looking for the minutest piece of evidence 63 00:03:38,680 --> 00:03:41,575 to place whoever it was at the crime scene. 64 00:03:41,600 --> 00:03:45,375 Finding the weapon is crucial to the investigation. 65 00:03:45,400 --> 00:03:47,695 The knife could have been discarded anywhere in the park, 66 00:03:47,720 --> 00:03:49,895 it might not even have been discarded in the park. 67 00:03:49,920 --> 00:03:53,015 Police search teams will do a fingertip search. 68 00:03:53,040 --> 00:03:57,375 Searching a big park area is quite a daunting task. 69 00:03:57,400 --> 00:04:00,015 There's so much other evidence there 70 00:04:00,040 --> 00:04:02,775 that's not related to the incident at all. 71 00:04:02,800 --> 00:04:05,695 Lots of innocent people that have travelled through there, 72 00:04:05,720 --> 00:04:07,255 their footprints might be there, 73 00:04:07,280 --> 00:04:09,895 their fingerprints and DNA on discarded items, 74 00:04:09,920 --> 00:04:13,175 dropped cigarettes or food items or a drink can, 75 00:04:13,200 --> 00:04:15,135 something in a bin, something like that, 76 00:04:15,160 --> 00:04:17,575 so the chances of recovering trace evidence 77 00:04:17,600 --> 00:04:19,495 from the scene is quite slim. 78 00:04:19,520 --> 00:04:22,335 It puts pressure on the investigation. 79 00:04:22,360 --> 00:04:24,975 The detectives can't rely fully on forensic evidence. 80 00:04:25,000 --> 00:04:27,855 Officers at the scene speak tojodie's friends. 81 00:04:27,880 --> 00:04:30,335 Police officers are gonna be dealing with people 82 00:04:30,360 --> 00:04:32,775 that have witnessed something traumatic to a friend. 83 00:04:32,800 --> 00:04:34,375 They're gonna be people in tears, 84 00:04:34,400 --> 00:04:36,415 they're gonna be people upset, distraught 85 00:04:36,440 --> 00:04:39,055 and that adds an added layer of difficulty. 86 00:04:39,080 --> 00:04:42,175 I need to know from you what you've seen, 87 00:04:42,200 --> 00:04:45,375 but you've just seen your friend seriously injured. 88 00:04:45,400 --> 00:04:47,095 In an ideal world, what you want from them 89 00:04:47,120 --> 00:04:50,655 is to sit them down and spend the next three or four hours 90 00:04:50,680 --> 00:04:53,575 with them going into detail about Jodie and her life. 91 00:04:53,600 --> 00:04:57,295 The police will be balancing the needs of the witness 92 00:04:57,320 --> 00:04:59,015 with the needs of the investigation. 93 00:04:59,040 --> 00:05:03,255 Witnesses state that two figures appeared behind Jodie, 94 00:05:03,280 --> 00:05:07,295 and one was wearing a fur-lined hooded coat. 95 00:05:07,320 --> 00:05:10,175 One of them stabbed Jodie in the back 96 00:05:10,200 --> 00:05:12,495 before disappearing into the darkness. 97 00:05:12,520 --> 00:05:15,055 So part of my role as a crime scene manager 98 00:05:15,080 --> 00:05:18,095 is also to try and ascertain why has this happened, 99 00:05:18,120 --> 00:05:20,455 what was the motive behind the attack, 100 00:05:20,480 --> 00:05:24,775 is it a random completely unprovoked attack, or... 101 00:05:24,800 --> 00:05:27,095 Is there some issues around friendship groups 102 00:05:27,120 --> 00:05:30,055 or boyfriend, girlfriend? 103 00:05:30,080 --> 00:05:32,695 There's lots of potential issues that someone may have 104 00:05:32,720 --> 00:05:34,615 with different areas of their life. 105 00:05:34,640 --> 00:05:38,335 The forensics team start at the attack site. 106 00:05:38,360 --> 00:05:41,775 Jodie was sat on the table with her feet on the actual bench 107 00:05:41,800 --> 00:05:44,975 and witnesses have said that she's been attacked from behind, 108 00:05:45,000 --> 00:05:47,775 so that area becomes really important. 109 00:05:47,800 --> 00:05:50,055 I would expect to find very little blood. 110 00:05:50,080 --> 00:05:54,615 A single stab wound will create a lot of internal bleeding, 111 00:05:54,640 --> 00:05:57,175 but not necessarily much external bleeding. 112 00:05:57,200 --> 00:06:02,495 So that park bench would be taken away for further forensic testing. 113 00:06:02,520 --> 00:06:05,095 That might have valuable DNA and fingerprint evidence on it. 114 00:06:06,440 --> 00:06:11,815 En route to hospital, the ambulance pulls over to work on Jodie 115 00:06:11,840 --> 00:06:14,055 in an attempt to save her life. 116 00:06:16,960 --> 00:06:20,615 Ancl I'll never forget the phone call... 117 00:06:22,120 --> 00:06:26,175 ...when he just said the words, 118 00:06:26,200 --> 00:06:28,415 "jodie's been stabbed... 119 00:06:28,440 --> 00:06:29,615 "and she's dead." 120 00:06:31,720 --> 00:06:35,415 None of us really knew what had happened. 121 00:06:35,440 --> 00:06:40,215 The Metropolitan Police are now dealing with a murder investigation. 122 00:06:40,240 --> 00:06:43,895 They must rely on forensics to help them catch the killer. 123 00:06:43,920 --> 00:06:47,015 The police don't have a lot of information to go on. 124 00:06:47,040 --> 00:06:48,935 No descriptions of anybody, 125 00:06:48,960 --> 00:06:51,575 what are we gonna do, how are we gonna solve this crime? 126 00:06:51,600 --> 00:06:53,735 There was no motive, 127 00:06:53,760 --> 00:06:56,295 no evidence, no reason. 128 00:06:56,320 --> 00:06:58,695 They had nothing to go on, basically. 129 00:06:58,720 --> 00:07:03,215 Cos there was no reason that we knew for it to happen. 130 00:07:03,240 --> 00:07:05,415 We were just in the dark. 131 00:07:14,200 --> 00:07:17,815 As the sun rises, CSls search for the knife 132 00:07:17,840 --> 00:07:22,775 that killed 17-year-old Jodie Chesney in her local park. 133 00:07:22,800 --> 00:07:24,735 Jodie was a child. 134 00:07:24,760 --> 00:07:26,295 Somebody's taken a child's life. 135 00:07:26,320 --> 00:07:27,695 Ancl on the face of it, 136 00:07:27,720 --> 00:07:31,375 there was absolutely no reason for this to have happened tojodie. 137 00:07:31,400 --> 00:07:34,375 There's a saying in murder investigations - 138 00:07:34,400 --> 00:07:38,375 to understand how somebody died, you have to understand how they lived. 139 00:07:38,400 --> 00:07:40,935 Ancl that's because in most murders, 140 00:07:40,960 --> 00:07:45,375 there's a link between the suspect and the victim. 141 00:07:46,720 --> 00:07:49,855 Detectives must build a picture of whojodie was 142 00:07:49,880 --> 00:07:51,335 and she associated with 143 00:07:51,360 --> 00:07:55,095 in a bid to determine any possible motive for her murder. 144 00:07:57,400 --> 00:08:02,375 jodie's social group was so sweet and innocent 145 00:08:02,400 --> 00:08:07,175 that you just didn't expect that to happen to any of them. 146 00:08:07,200 --> 00:08:10,535 They were a lovely bunch of kids, really, really nice, 147 00:08:10,560 --> 00:08:12,575 and really good for her as well. 148 00:08:12,600 --> 00:08:14,815 They used to call themselves proud geeks, 149 00:08:14,840 --> 00:08:17,015 cos they all were a little bit different 150 00:08:17,040 --> 00:08:20,855 from your normal crowd of kids, but they were so lovely. 151 00:08:20,880 --> 00:08:22,335 And she adored them. 152 00:08:22,360 --> 00:08:24,295 She would do anything for anyone. 153 00:08:24,320 --> 00:08:26,375 Very proud of her. 154 00:08:26,400 --> 00:08:30,695 She really kind of blossomed as soon she started Scouts. 155 00:08:30,720 --> 00:08:34,975 She loved being outdoors, she was doing her Duke of Edinburgh Award, 156 00:08:35,000 --> 00:08:36,935 she was actually clue to finish the last one 157 00:08:36,960 --> 00:08:38,815 a couple of months after she cited. 158 00:08:38,840 --> 00:08:42,055 She was always into music as well, and she loved playing music, 159 00:08:42,080 --> 00:08:43,495 she learnt how to play the piano. 160 00:08:43,520 --> 00:08:50,015 She learnt it by ear and it was just amazing to watch her play it. 161 00:08:55,400 --> 00:09:00,095 The news ofjodie's murder spreads across the community. 162 00:09:00,120 --> 00:09:03,175 First to the scene is local journalist Liam Coleman. 163 00:09:05,160 --> 00:09:07,495 About half past seven in the morning 164 00:09:07,520 --> 00:09:09,535 and there was a police cordon all around the park, 165 00:09:09,560 --> 00:09:12,575 there was a tent over the bench where Jodie had been stabbed. 166 00:09:13,760 --> 00:09:17,735 Everyone down here was shook, the community was grieving. 167 00:09:17,760 --> 00:09:19,495 People were angry that this had happened, 168 00:09:19,520 --> 00:09:21,215 but I think the community felt determined 169 00:09:21,240 --> 00:09:22,975 to catch whoever had done this. 170 00:09:23,000 --> 00:09:26,815 The shock ofjodie's death has a deep impact. 171 00:09:26,840 --> 00:09:28,695 It wasn't just a case of 172 00:09:28,720 --> 00:09:32,135 a few bunches of flowers had been laid down here, 173 00:09:32,160 --> 00:09:36,015 you know, there was hundreds of bunches of flowers down here. 174 00:09:36,040 --> 00:09:40,255 And very quickly, everywhere started to turn purple, 175 00:09:40,280 --> 00:09:42,135 so purple was jodie's favourite colour, 176 00:09:42,160 --> 00:09:43,615 it was the colour she dyed her hair, 177 00:09:43,640 --> 00:09:45,615 and the whole of Romford, in particular as well, 178 00:09:45,640 --> 00:09:47,815 had turned purple in mourning. 179 00:09:47,840 --> 00:09:49,855 And we changed the masthead to purple. 180 00:09:49,880 --> 00:09:52,895 I just think it was a very strong emotive thing to do 181 00:09:52,920 --> 00:09:55,095 and I think that that outpouring initially 182 00:09:55,120 --> 00:09:58,135 was reflective of the fact that she was obviously very popular 183 00:09:58,160 --> 00:10:00,415 and very much-loved, 184 00:10:00,440 --> 00:10:04,055 and also someone that just made it even more shocking 185 00:10:04,080 --> 00:10:05,895 that this would have happened to her. 186 00:10:05,920 --> 00:10:08,255 justice for Jodie! 187 00:10:08,280 --> 00:10:10,015 CHEERING 188 00:10:10,040 --> 00:10:12,975 There was nothing in her life 189 00:10:13,000 --> 00:10:15,895 that would indicate why someone would kill her, 190 00:10:15,920 --> 00:10:19,295 why someone would inflict so much violence upon her. 191 00:10:19,320 --> 00:10:22,615 It's that emotive part of the case that captured the attention 192 00:10:22,640 --> 00:10:25,535 and the interest of the press. 193 00:10:25,560 --> 00:10:29,295 Jodie is the first teenage girl to be killed in the capital this year, 194 00:10:29,320 --> 00:10:33,855 but the 18th person to die in a homicide in London in 2019. 195 00:10:33,880 --> 00:10:35,295 The media circus comes, you know, 196 00:10:35,320 --> 00:10:37,215 the world's media, essentially, to be honest, 197 00:10:37,240 --> 00:10:39,975 it got broadcast, you've got everyone there. 198 00:10:40,000 --> 00:10:43,935 It was hard to have the press attention, I mean, 199 00:10:43,960 --> 00:10:47,695 early, well, probably eight o'clock in the morning on the Saturday, 200 00:10:47,720 --> 00:10:50,175 there was already press knocking at our door 201 00:10:50,200 --> 00:10:53,735 when we didn't even know what was really going on ourselves, 202 00:10:53,760 --> 00:10:56,095 and they were relentless. 203 00:10:56,120 --> 00:11:01,655 I can see why they were interested because it was so random, 204 00:11:01,680 --> 00:11:04,335 and it-it was so out of the blue. 205 00:11:04,360 --> 00:11:07,255 But we just at that point wanted to be left alone 206 00:11:07,280 --> 00:11:10,975 to try and kind of deal with what was going on. 207 00:11:12,560 --> 00:11:14,415 Police are hopeful the pathologist 208 00:11:14,440 --> 00:11:16,815 can build a profile of the murder weapon 209 00:11:16,840 --> 00:11:20,215 by analysing the wounds during post-mortem. 210 00:11:20,240 --> 00:11:22,495 A single stab wound through the back, 211 00:11:22,520 --> 00:11:25,295 that is clearly a very determined attack. 212 00:11:26,680 --> 00:11:29,495 The pathologist was able to say it was a single-edged blade 213 00:11:29,520 --> 00:11:33,175 with a non-serrated edge that penetrated the wound, 214 00:11:33,200 --> 00:11:36,295 and was 18 cm in length. 215 00:11:36,320 --> 00:11:38,655 That may not sound a lot, but what that actually meant was 216 00:11:38,680 --> 00:11:43,495 the would inflicted on Jodie almost penetrated the whole of her body. 217 00:11:43,520 --> 00:11:45,695 I've seen a lot of stab wounds in my career - 218 00:11:45,720 --> 00:11:50,415 very few I've seen as horrendous as this. 219 00:11:50,440 --> 00:11:53,135 After extensive fingertip searches, 220 00:11:53,160 --> 00:11:55,975 CSls have not located the murder weapon, 221 00:11:56,000 --> 00:11:59,415 and believe the killer took it with them when they fled the scene. 222 00:12:00,760 --> 00:12:05,775 It can be quite disheartening if there's not much forensic evidence. 223 00:12:05,800 --> 00:12:08,775 It puts a lot of pressure on the digital forensics side 224 00:12:08,800 --> 00:12:12,415 to try and locate either mobile phones pinging off certain masts 225 00:12:12,440 --> 00:12:15,455 or CCTV either from people's houses 226 00:12:15,480 --> 00:12:18,295 or on the street, or maybe from a passing bus 227 00:12:18,320 --> 00:12:23,415 to be able to link a potential route that offenders might have taken. 228 00:12:23,440 --> 00:12:26,055 There's a team of investigators that are allocated 229 00:12:26,080 --> 00:12:29,175 to basically trawl through all CTV. 230 00:12:31,080 --> 00:12:34,575 The CCTV team have located Jodie and her friends 231 00:12:34,600 --> 00:12:38,175 heading to the park just hours before her murder. 232 00:12:38,200 --> 00:12:41,695 But they have yet to find any suspects fleeing the scene, 233 00:12:41,720 --> 00:12:45,055 and are still no closer to identifying the attackers. 234 00:12:46,640 --> 00:12:50,175 We haven't got a lot to go on. The police need information. 235 00:12:50,200 --> 00:12:52,335 Police don't solve murders on their own. 236 00:12:52,360 --> 00:12:53,775 They need the help of the public. 237 00:12:53,800 --> 00:12:56,415 All police know about the attackers 238 00:12:56,440 --> 00:12:59,855 is that one was wearing a fur-lined hooded coat. 239 00:12:59,880 --> 00:13:04,095 Feeling the pressure, police turn to the press for help. 240 00:13:04,120 --> 00:13:06,735 That was something that they do when they are struggling, you know, 241 00:13:06,760 --> 00:13:08,815 that's something that they put out 242 00:13:08,840 --> 00:13:11,695 when they don't necessarily have huge amounts of evidence to go off. 243 00:13:11,720 --> 00:13:16,095 The media and police sometimes will work hand in glove. 244 00:13:16,120 --> 00:13:19,255 The media can be an incredibly important mouthpiece. 245 00:13:19,280 --> 00:13:23,335 On the night of the murder, between the hours of 7 and 11pm, 246 00:13:23,360 --> 00:13:28,375 there are many people who had the dashcam and potentially CCTV. 247 00:13:28,400 --> 00:13:30,335 WOMAN: We're appealing for any witnesses 248 00:13:30,360 --> 00:13:32,935 who have yet to speak with the police to call me. 249 00:13:32,960 --> 00:13:34,215 There will be witnesses 250 00:13:34,240 --> 00:13:37,055 and people with information that will prove crucial. 251 00:13:37,080 --> 00:13:39,575 Although the description of the suspect is limited, 252 00:13:39,600 --> 00:13:42,455 I am certain that people will have noticed something suspicious. 253 00:13:42,480 --> 00:13:45,095 I need those people to call me. 254 00:13:46,400 --> 00:13:50,175 That media frenzy circus, if you like, did help the investigation. 255 00:13:50,200 --> 00:13:53,695 A witness came forward and said that he was in that area 256 00:13:53,720 --> 00:13:57,255 around that time driving his car, and he got stuck behind a car, 257 00:13:57,280 --> 00:14:00,015 and it didn't move until two men came running quickly, 258 00:14:00,040 --> 00:14:03,255 got in, and it drove off at speed. 259 00:14:03,280 --> 00:14:05,015 This is now crucial. 260 00:14:05,040 --> 00:14:07,095 This is probably the first sighting 261 00:14:07,120 --> 00:14:09,695 away from the witnesses of our suspects. 262 00:14:09,720 --> 00:14:14,375 The witness is sure the car is an older model Vauxhall Corsa. 263 00:14:15,480 --> 00:14:18,535 Police scan their databases. 264 00:14:18,560 --> 00:14:20,815 just five miles away from the crime scene, 265 00:14:20,840 --> 00:14:23,375 one has been abandoned. 266 00:14:23,400 --> 00:14:27,215 This clearly would ramp up the crime scene investigation, 267 00:14:27,240 --> 00:14:29,255 and this would then be a second scene 268 00:14:29,280 --> 00:14:32,735 that would need to be examined by a fresh set of CSls. 269 00:14:32,760 --> 00:14:36,455 Speed is of the essence, to be able to get there and preserve the scene 270 00:14:36,480 --> 00:14:37,655 and recover any evidence 271 00:14:37,680 --> 00:14:42,295 and try and link this vehicle back to he scene of the attack 272 00:14:42,320 --> 00:14:45,415 or back to offenders that may have escaped 273 00:14:45,440 --> 00:14:48,055 using this vehicle from that crime scene. 274 00:14:48,080 --> 00:14:52,695 We would also look at the tyres because if there's any tyre marks 275 00:14:52,720 --> 00:14:55,855 outside the crime scene, say on the road or on the footpath, 276 00:14:55,880 --> 00:14:57,415 we may be able to link that vehicle 277 00:14:57,440 --> 00:15:00,215 back to those tyre marks at that scene. 278 00:15:00,240 --> 00:15:03,255 We would initially photograph the car in situ, 279 00:15:03,280 --> 00:15:06,695 and then get the vehicle recovered to a forensic recovery garage, 280 00:15:06,720 --> 00:15:10,495 and it's at that stage that the car will be fully searched. 281 00:15:10,520 --> 00:15:14,535 Digital forensics trace the vehicle's journey through AN PR 282 00:15:14,560 --> 00:15:18,535 and detectives focus on who abandoned the vehicle. 283 00:15:18,560 --> 00:15:21,095 Who owns this car? What do we know about them? 284 00:15:21,120 --> 00:15:22,695 The officers that attended the scene 285 00:15:22,720 --> 00:15:26,655 would run the registration number through the police national computer 286 00:15:26,680 --> 00:15:28,215 and what that told them 287 00:15:28,240 --> 00:15:31,775 was that the car had been reported stolen on the Friday, 288 00:15:31,800 --> 00:15:33,895 so the clay that Jodie was murdered. 289 00:15:36,760 --> 00:15:40,655 Police had to understand is that true or not? 290 00:15:40,680 --> 00:15:44,895 I think personally why has this car been stolen, why, you know, 291 00:15:44,920 --> 00:15:46,895 who would wanna steal that car? 292 00:15:46,920 --> 00:15:50,415 It's not a Bentley, it's not a £200,000 car. 293 00:15:50,440 --> 00:15:54,935 People steal cars to commit crimes because then it adds an extra layer 294 00:15:54,960 --> 00:15:58,015 of essentially trying to make themselves safe, 295 00:15:58,040 --> 00:15:59,975 make it harder for police to find them. 296 00:16:00,000 --> 00:16:02,575 You know, you steal someone's car, go and burn it out afterwards, 297 00:16:02,600 --> 00:16:04,255 you're destroying evidence. 298 00:16:04,280 --> 00:16:08,615 It's not unusual for people that have used their own cars 299 00:16:08,640 --> 00:16:10,415 in criminality, 300 00:16:10,440 --> 00:16:14,095 especially in serious incidents, will think, "What am I gonna do? 301 00:16:14,120 --> 00:16:17,695 "How am I gonna distance myself from this crime?" 302 00:16:17,720 --> 00:16:20,815 So it's not unusual for people to phone up police and say, 303 00:16:20,840 --> 00:16:23,175 "Do you know what, my car was stolen, 304 00:16:23,200 --> 00:16:25,935 "and it was stolen before this crime was committed 305 00:16:25,960 --> 00:16:27,215 "so it can't have been me." 306 00:16:27,240 --> 00:16:30,095 Are they telling the truth or not? 307 00:16:30,120 --> 00:16:33,295 Ancl one of the ways you would that is by looking at the person 308 00:16:33,320 --> 00:16:37,135 and understanding their history, what kind of person are they? 309 00:16:37,160 --> 00:16:38,335 In this instance, 310 00:16:38,360 --> 00:16:42,055 there was obviously things within this person's history, 311 00:16:42,080 --> 00:16:46,095 within this person's criminality, that make the officers suspicious. 312 00:16:46,120 --> 00:16:50,495 Detectives discover the owner of the car has prior convictions, 313 00:16:50,520 --> 00:16:53,375 including for the supply of cocaine, 314 00:16:53,400 --> 00:16:56,695 which date back to when he was just 14. 315 00:16:58,400 --> 00:17:00,335 Back at the forensic garage, 316 00:17:00,360 --> 00:17:04,615 CSls seize all possible exhibits from the vehicle. 317 00:17:04,640 --> 00:17:07,735 Full forensic examination done of that vehicle, 318 00:17:07,760 --> 00:17:10,375 which would include searching for weapons, 319 00:17:10,400 --> 00:17:12,415 for the knife that's outstanding, 320 00:17:12,440 --> 00:17:15,655 it would be searching for blood and for fingerprints 321 00:17:15,680 --> 00:17:18,895 and for potentialfibres on the car seats. 322 00:17:18,920 --> 00:17:20,855 The vehicle will be fingerprinted. 323 00:17:20,880 --> 00:17:23,015 We would tend to use aluminium powder 324 00:17:23,040 --> 00:17:24,495 on the outside of a vehicle, 325 00:17:24,520 --> 00:17:26,695 and this is almost like a silver powder 326 00:17:26,720 --> 00:17:30,175 that adheres to the sweat of the fingerprints, 327 00:17:30,200 --> 00:17:33,135 and we use a brush called a zephyr brush 328 00:17:33,160 --> 00:17:36,575 and lightly dusting the vehicle would reveal any fingerprints 329 00:17:36,600 --> 00:17:39,455 which are then lifted with fingerprinting tape. 330 00:17:39,480 --> 00:17:44,095 CSI discover a palm print on the bonnet of the car. 331 00:17:44,120 --> 00:17:48,135 It's sent off to experts to compare against the national database 332 00:17:48,160 --> 00:17:50,695 while CSls focus on the car's interior. 333 00:17:53,320 --> 00:17:56,335 There's a figurehead of a cleaning spray 334 00:17:56,360 --> 00:17:58,335 in the foot well of the vehicle. 335 00:17:59,560 --> 00:18:02,415 From a crime scene examinations perspective, 336 00:18:02,440 --> 00:18:05,495 this means that maybe the vehicle might have been cleaned. 337 00:18:05,520 --> 00:18:07,015 Maybe the vehicle is linked, 338 00:18:07,040 --> 00:18:09,855 and they might have tried to get rid of fingerprint 339 00:18:09,880 --> 00:18:12,015 or DNA evidence within that vehicle. 340 00:18:12,040 --> 00:18:13,895 Doesn't mean we don't give up hope 341 00:18:13,920 --> 00:18:16,975 and we don't still do a full examination of the vehicle, 342 00:18:17,000 --> 00:18:19,895 because we will use all techniques available 343 00:18:19,920 --> 00:18:21,695 to be able to catch the killer. 344 00:18:23,080 --> 00:18:24,815 As the exhibits are sent to the lab, 345 00:18:24,840 --> 00:18:28,335 digital forensics team look through the CCTV 346 00:18:28,360 --> 00:18:30,135 for black cars near the crime scene. 347 00:18:33,160 --> 00:18:36,255 A camera on Retford Road captures some movement 348 00:18:36,280 --> 00:18:38,335 just minutes beforejodie's murder. 349 00:18:38,360 --> 00:18:43,415 The team share the results with forensic analyst Ashley Windsor. 350 00:18:44,600 --> 00:18:48,335 A car pulls up in the dark and then it stops, 351 00:18:48,360 --> 00:18:52,015 and it stops for a short period of time, 352 00:18:52,040 --> 00:18:56,295 and you can see some what I would describe as disturbances 353 00:18:56,320 --> 00:18:58,615 which makes identification very difficult. 354 00:18:58,640 --> 00:19:03,175 I've had a long look at this bit of footage, 355 00:19:03,200 --> 00:19:06,775 all the images that were ever recorded in this clip. 356 00:19:06,800 --> 00:19:11,615 Even though this footage is very poor resolution, it's very dark 357 00:19:11,640 --> 00:19:13,695 there's very little detail in it, 358 00:19:13,720 --> 00:19:19,135 it shows two figures heading towards the scene of the crime. 359 00:19:19,160 --> 00:19:22,855 I want to know who leaves the car and goes into the park. 360 00:19:25,720 --> 00:19:28,815 The footage is very low quality. 361 00:19:28,840 --> 00:19:31,255 Ashley needs to analyse each frame 362 00:19:31,280 --> 00:19:35,335 to uncover any leads as to who these figures are. 363 00:19:35,360 --> 00:19:38,095 The digital forensics team look for other angles. 364 00:19:40,280 --> 00:19:43,335 From trawling the CCTV in the area, 365 00:19:43,360 --> 00:19:46,135 on one piece of footage, in one corner, 366 00:19:46,160 --> 00:19:49,215 that you could miss if you blinked, 367 00:19:49,240 --> 00:19:54,855 what the CCTV showed was two figures leaving the park, 368 00:19:54,880 --> 00:19:57,415 getting into a car, and the car driving off. 369 00:19:57,440 --> 00:19:59,615 So what that told the investigators 370 00:19:59,640 --> 00:20:02,535 that they weren't just looking for two people, 371 00:20:02,560 --> 00:20:04,495 they now had a getaway driver. 372 00:20:04,520 --> 00:20:09,055 They now have at least three people who were involved in jodie's murder. 373 00:20:09,080 --> 00:20:13,295 The breakthrough evidence puts the Corsa at the crime scene. 374 00:20:13,320 --> 00:20:15,975 Knowing the owner's criminality, 375 00:20:16,000 --> 00:20:18,255 police believe he could be the getaway driver. 376 00:20:19,560 --> 00:20:22,375 He is the investigation's best lead 377 00:20:22,400 --> 00:20:24,975 to who was behind the murder ofjodie Chesney. 378 00:20:26,160 --> 00:20:28,615 The owner of the car is our first suspect. 379 00:20:28,640 --> 00:20:32,935 This is somebody we believe was involved in the murder ofjodie, 380 00:20:32,960 --> 00:20:35,735 and steps will now be taken to arrest. 381 00:20:44,000 --> 00:20:49,135 Police investigating the stabbing of girl scoutjodie Chesney 382 00:20:49,160 --> 00:20:52,695 are under pressure to find her killers. 383 00:20:52,720 --> 00:20:55,495 justice for Jodie! 384 00:20:55,520 --> 00:21:00,095 Digital forensic expert have recovered CCTV of two figures 385 00:21:00,120 --> 00:21:03,975 entering the park moments beforejodie was killed, 386 00:21:04,000 --> 00:21:07,095 but the images are too dark to identify them. 387 00:21:07,120 --> 00:21:09,295 The team's most promising lead 388 00:21:09,320 --> 00:21:12,615 is a black Vauxhall Corsa they've linked to the murder. 389 00:21:12,640 --> 00:21:15,935 Now, police are planning the arrest of their first suspect, 390 00:21:15,960 --> 00:21:20,855 the owner of the car, after learning he has links to criminal gangs. 391 00:21:20,880 --> 00:21:23,895 The owner of the car is our first suspect 392 00:21:23,920 --> 00:21:26,095 and steps will now be taken to arrest him. 393 00:21:26,120 --> 00:21:29,615 Police intelligence tracks the man down in Leicester, 394 00:21:29,640 --> 00:21:32,135 and officers bring him in to custody. 395 00:21:32,160 --> 00:21:34,175 To hear an arrest has been made, 396 00:21:34,200 --> 00:21:36,375 it's a feeling of relief, I think, to an extent, 397 00:21:36,400 --> 00:21:39,375 cos you think "OK, something's gonna happen now." 398 00:21:39,400 --> 00:21:42,935 But unless they have that hard evidence, then they can't charge. 399 00:21:42,960 --> 00:21:45,135 When questioned, the owner of the car 400 00:21:45,160 --> 00:21:47,335 gives police a written statement. 401 00:21:47,360 --> 00:21:50,655 He was driving the car at the park on the night of the murder... 402 00:21:53,400 --> 00:21:55,575 ...but says it was two other men 403 00:21:55,600 --> 00:21:57,975 that got out and walked into the park. 404 00:21:59,240 --> 00:22:01,015 He thought it was for a drug deal, 405 00:22:01,040 --> 00:22:03,375 and says he knew nothing about the murder 406 00:22:03,400 --> 00:22:07,015 and refuses to name the people he was with. 407 00:22:07,040 --> 00:22:09,975 Police need to determine if the owner of the car 408 00:22:10,000 --> 00:22:13,895 is telling the truth, and identify the two men he was with. 409 00:22:16,160 --> 00:22:18,015 The black car linked to the murder 410 00:22:18,040 --> 00:22:21,095 provides the team with a much-needed forensic opportunity. 411 00:22:23,160 --> 00:22:24,975 A trigger from a cleaning product 412 00:22:25,000 --> 00:22:27,615 and a palm print harvested from the car bonnet 413 00:22:27,640 --> 00:22:30,095 have been sent for further analysis. 414 00:22:33,320 --> 00:22:35,135 As a promising manager, 415 00:22:35,160 --> 00:22:37,615 you're always searching and searching 416 00:22:37,640 --> 00:22:39,455 and trying to link offenders to a scene 417 00:22:39,480 --> 00:22:41,655 because you want justice for the family. 418 00:22:41,680 --> 00:22:44,415 If you're able to find some conclusive evidence, 419 00:22:44,440 --> 00:22:45,895 it's a really good feeling. 420 00:22:47,760 --> 00:22:50,055 Forensics recover a male DNA profile 421 00:22:50,080 --> 00:22:52,255 from the nozzle of a cleaning bottle, 422 00:22:52,280 --> 00:22:55,255 and find a match to a 16-year-old boy 423 00:22:55,280 --> 00:22:58,815 with previous drug convictions. 424 00:22:58,840 --> 00:23:04,055 The palm print is found to belong to 19-year-old Svenson Ong-A-Kwie. 425 00:23:04,080 --> 00:23:07,295 He has previous convictions for dealing Class A drugs, 426 00:23:07,320 --> 00:23:11,015 handling stolen goods and possessing a knife. 427 00:23:11,040 --> 00:23:15,255 Investigators now have the names of three people linked to the car 428 00:23:15,280 --> 00:23:18,655 seen at the crime scene, but they still need to determine 429 00:23:18,680 --> 00:23:21,375 if any of them are the figures entering the park 430 00:23:21,400 --> 00:23:23,135 moments before the murder. 431 00:23:23,160 --> 00:23:25,895 On the face of it, that's great evidence. 432 00:23:25,920 --> 00:23:28,535 We know there are at least three people. 433 00:23:28,560 --> 00:23:30,735 Have we got the right three people? 434 00:23:30,760 --> 00:23:34,375 But the problem is, this evidence can't be timed. 435 00:23:34,400 --> 00:23:36,935 When did that bottle go in the car? 436 00:23:36,960 --> 00:23:39,215 When did the person touch the bonnet? 437 00:23:39,240 --> 00:23:43,575 You can't time a palm print, so as much of a breakthrough as this is, 438 00:23:43,600 --> 00:23:45,255 these were just indications 439 00:23:45,280 --> 00:23:48,535 as to people who may have been involved in jodie's murder. 440 00:23:48,560 --> 00:23:51,415 We need to find additional evidence to this. 441 00:23:51,440 --> 00:23:55,095 They need to put them together on the day Jodie was murdered. 442 00:23:56,480 --> 00:23:59,295 Having admitted driving the car, 443 00:23:59,320 --> 00:24:02,615 digital forensics teams use the owner of the car's cell site data 444 00:24:02,640 --> 00:24:06,895 to build a picture of who he was with at the time of the murder. 445 00:24:06,920 --> 00:24:10,575 They recover all possible CCTV 446 00:24:10,600 --> 00:24:16,375 and get a hit from a cafe a few hours beforejodie was attacked. 447 00:24:19,040 --> 00:24:21,215 In this footage we have 448 00:24:21,240 --> 00:24:26,655 the owner of the car in association with other persons at the table. 449 00:24:26,680 --> 00:24:32,575 There's quite a lot of this footage, and I can say that the two people 450 00:24:32,600 --> 00:24:37,135 he is meeting are the other two suspects. 451 00:24:40,600 --> 00:24:43,455 Later that evening, cell site evidence 452 00:24:43,480 --> 00:24:45,975 shows the trio are together again, 453 00:24:46,000 --> 00:24:50,575 travelling up the A12 in a car towards Romford, 454 00:24:50,600 --> 00:24:53,735 just nine minutes before Jodie lost her life. 455 00:24:57,680 --> 00:24:59,695 It's great evidence. 456 00:24:59,720 --> 00:25:06,015 One thing we haven't got is a link between them and Jodie. 457 00:25:06,040 --> 00:25:09,855 What was it that led those men to go to the park, 458 00:25:09,880 --> 00:25:12,095 and did they takejodie's life on that night? 459 00:25:12,120 --> 00:25:15,255 These are potentially dangerous individuals. 460 00:25:15,280 --> 00:25:18,535 Did they just kill somebody for no apparent reason 461 00:25:18,560 --> 00:25:20,335 in the most vicious way? 462 00:25:21,680 --> 00:25:25,535 With still no possible motive as to why these men would attack Jodie, 463 00:25:25,560 --> 00:25:28,295 police are feeling the pressure. 464 00:25:28,320 --> 00:25:30,215 They arrest the 16-year-old. 465 00:25:30,240 --> 00:25:34,695 In custody, he also admits being in the car on the night of the murder, 466 00:25:34,720 --> 00:25:38,655 but insists he was not one of the men that entered the park. 467 00:25:38,680 --> 00:25:41,135 He refuses to name who did. 468 00:25:41,160 --> 00:25:43,815 Police rush to arrest Ong-A-Kwie, 469 00:25:43,840 --> 00:25:46,975 but he is not at his registered address. 470 00:25:47,000 --> 00:25:49,855 This is now a manhunt. 471 00:25:49,880 --> 00:25:53,135 They need to find this person as a matter of urgency. 472 00:25:53,160 --> 00:25:54,415 When people commit murders, 473 00:25:54,440 --> 00:25:56,815 they don't always make it easy for police to find them. 474 00:25:56,840 --> 00:26:01,575 It could something as simple as stopping using your mobile phone, 475 00:26:01,600 --> 00:26:04,135 or it could be they flee the country. 476 00:26:04,160 --> 00:26:08,175 Extra resources will be brought in to try and find Ong-A-Kwie. 477 00:26:08,200 --> 00:26:11,495 As the pressure heightens to apprehend the prime suspect... 478 00:26:13,280 --> 00:26:17,095 ...jodie's friends hold a memorial. 479 00:26:18,840 --> 00:26:20,775 One of the women said, 480 00:26:20,800 --> 00:26:23,695 "She used to help me and my children cross the road in the mornings, 481 00:26:23,720 --> 00:26:25,375 "every clay she'd see us 482 00:26:25,400 --> 00:26:27,655 "and she'd see me struggle and she'd come and help." 483 00:26:27,680 --> 00:26:31,295 Ancl it was just really nice to hear these people knew who she was, 484 00:26:31,320 --> 00:26:33,295 and it didn't matter who you were to her, 485 00:26:33,320 --> 00:26:36,055 she would help, she would go out of her way to make sure you were OK. 486 00:26:36,080 --> 00:26:39,095 I reported on the tributes from the college. 487 00:26:39,120 --> 00:26:45,375 Ultimately, it led to me being invited to jodie's funeral. 488 00:26:45,400 --> 00:26:48,775 I think they must have been happy with the way that we'd covered it 489 00:26:48,800 --> 00:26:51,455 and what photographs we'd used and all of those things. 490 00:26:51,480 --> 00:26:55,855 Jodie he was given a guard of honour from her Scout group. 491 00:26:55,880 --> 00:26:59,495 It was incredibly moving. 492 00:26:59,520 --> 00:27:01,695 Jodie was not a person that... 493 00:27:01,720 --> 00:27:04,735 would ever have been involved in anything sinister, 494 00:27:04,760 --> 00:27:07,455 to be honest, a person who had no enemies, 495 00:27:07,480 --> 00:27:10,615 someone that was loved by so many people. 496 00:27:10,640 --> 00:27:13,895 Someone that had no affiliations to gangs. 497 00:27:13,920 --> 00:27:16,135 She was a Scout, you know, she was an innocent person, 498 00:27:16,160 --> 00:27:17,655 one of the last people in the world 499 00:27:17,680 --> 00:27:19,935 you would think something like this would happen to. 500 00:27:23,560 --> 00:27:25,575 Nine days in to the investigation, 501 00:27:25,600 --> 00:27:30,455 the digital forensics team have a result from Ong-A-Kwie's phone data. 502 00:27:30,480 --> 00:27:33,615 It's still being used. 503 00:27:33,640 --> 00:27:36,655 He's at a new address in Dagenham. 504 00:27:36,680 --> 00:27:40,855 He's on that roof. Oh, he's through the conservatory. 505 00:27:40,880 --> 00:27:43,135 Through the conservatory next door. 506 00:27:43,160 --> 00:27:45,935 Police officer Stay where you are! 507 00:27:45,960 --> 00:27:48,415 Stay where you are! 508 00:27:49,640 --> 00:27:50,975 Police officer. 509 00:27:51,000 --> 00:27:52,975 Do not move! Show me your hands. 510 00:27:53,000 --> 00:27:55,015 Show me your hands now! 511 00:27:55,040 --> 00:27:57,175 Get over here now. 512 00:27:57,200 --> 00:27:58,855 Other side, other side. 513 00:27:58,880 --> 00:28:01,055 SHOUTING 514 00:28:02,200 --> 00:28:07,415 INDISTINCT SPEECH 515 00:28:07,440 --> 00:28:09,935 You're under arrest, mate. 516 00:28:09,960 --> 00:28:11,375 Suspicion of murder. 517 00:28:11,400 --> 00:28:13,775 Suspicion of murder. What? 518 00:28:13,800 --> 00:28:16,615 Murder? Murder. 519 00:28:16,640 --> 00:28:18,975 I ain't killed no-one! 520 00:28:19,000 --> 00:28:22,375 Svenson Ong-A-Kwie is taken into custody. 521 00:28:23,600 --> 00:28:28,855 Also fleeing the address is a 17-year-old called Aaron Isaacs. 522 00:28:28,880 --> 00:28:32,295 He's arrested for assisting an offender. 523 00:28:32,320 --> 00:28:35,495 When someone's wanted for a serious offence, 524 00:28:35,520 --> 00:28:39,015 if anybody helps them they can carry out that arrest. 525 00:28:39,040 --> 00:28:41,935 It will be the murder investigation team to try and establish, 526 00:28:41,960 --> 00:28:43,815 well, is Isaacs involved? 527 00:28:43,840 --> 00:28:46,535 If this person was involved, 528 00:28:46,560 --> 00:28:48,815 he's likely to have evidence on him, 529 00:28:48,840 --> 00:28:50,975 and if he is, what is his involvement? 530 00:28:52,280 --> 00:28:55,135 In custody, the teens offer no comment. 531 00:28:55,160 --> 00:28:58,895 Police need to work quickly to build their case. 532 00:28:58,920 --> 00:29:02,655 CSls rush to search the suspect's homes. 533 00:29:02,680 --> 00:29:04,895 When the house searches are conducted, 534 00:29:04,920 --> 00:29:06,535 there should be a list of items 535 00:29:06,560 --> 00:29:09,455 that the crime scene manager has identified as still outstanding 536 00:29:09,480 --> 00:29:10,975 from the scene, 537 00:29:11,000 --> 00:29:14,135 and it's important that they search for blood-stained clothing 538 00:29:14,160 --> 00:29:15,975 and fur-lined hoods 539 00:29:16,000 --> 00:29:18,535 and a potential knife with a long blade. 540 00:29:18,560 --> 00:29:21,015 Two knives were found. 541 00:29:21,040 --> 00:29:24,295 These knives become important 542 00:29:24,320 --> 00:29:26,935 because they may well be the murder weapon. 543 00:29:26,960 --> 00:29:29,295 They're seized, examined for blood, 544 00:29:29,320 --> 00:29:34,895 fingerprinted and compared against the pathologist report. 545 00:29:34,920 --> 00:29:37,415 As the exhibits are sent to the lab, 546 00:29:37,440 --> 00:29:39,615 detectives need to prove that 547 00:29:39,640 --> 00:29:42,535 Ong-A-Kwie is one of the men who entered the park. 548 00:29:42,560 --> 00:29:44,215 They call on Ashley Windsor 549 00:29:44,240 --> 00:29:48,135 to identify him on all of the investigation's CCTV. 550 00:29:50,400 --> 00:29:52,815 When you're trying to identify the person, 551 00:29:52,840 --> 00:29:55,655 you have to look at the entire package of the person, 552 00:29:55,680 --> 00:29:59,895 and when you're doing that and you study them for long enough, 553 00:29:59,920 --> 00:30:02,415 you might start finding movement traits. 554 00:30:02,440 --> 00:30:04,335 I now want to see what they look like 555 00:30:04,360 --> 00:30:07,575 at different distances, different heights 556 00:30:07,600 --> 00:30:09,535 and under different lighting conditions 557 00:30:09,560 --> 00:30:12,735 because I need to be able to identify that person 558 00:30:12,760 --> 00:30:15,375 under poor lighting conditions at a later stage. 559 00:30:15,400 --> 00:30:19,455 Ashley starts with a clear piece of footage of Ong-A-Kwie. 560 00:30:19,480 --> 00:30:23,735 In this clip, we can see the combination of clothes that he has 561 00:30:23,760 --> 00:30:28,815 in daylight, we can see his size and we can see how he moves. 562 00:30:28,840 --> 00:30:33,495 He's tall, slim, athletic build and he has, 563 00:30:33,520 --> 00:30:38,575 because he has long legs, he has quite a wide, rolling stride. 564 00:30:38,600 --> 00:30:40,735 His top garment is very dark 565 00:30:40,760 --> 00:30:44,615 and it has a fur-trimmed hood. 566 00:30:45,840 --> 00:30:48,055 The jacket matches the witness' description 567 00:30:48,080 --> 00:30:51,535 of one ofjodie's killers. 568 00:30:51,560 --> 00:30:54,375 Next, Ashley looks at darker footage, 569 00:30:54,400 --> 00:30:56,695 taken an hour before jodie's murder, 570 00:30:56,720 --> 00:31:00,215 that shows two men arriving at the hostel. 571 00:31:00,240 --> 00:31:04,775 You see two figures and they head towards a car. 572 00:31:04,800 --> 00:31:06,655 The taller of the two figures 573 00:31:06,680 --> 00:31:10,055 appears to have the same wide stride. 574 00:31:10,080 --> 00:31:13,215 They travel through different forms of lighting, 575 00:31:13,240 --> 00:31:15,495 and I can see how their clothing changes 576 00:31:15,520 --> 00:31:20,095 you can use that as your basis to work on the next clip. 577 00:31:20,120 --> 00:31:23,455 Ashley compares his findings with low quality footage 578 00:31:23,480 --> 00:31:27,455 from the crime scene of the two men leaving the car 579 00:31:27,480 --> 00:31:29,495 and walking towards the park. 580 00:31:29,520 --> 00:31:32,775 You need someone who completely understands 581 00:31:32,800 --> 00:31:37,175 what they are looking at, so that's where the expertise comes in. 582 00:31:37,200 --> 00:31:40,495 You look at all the attributes of one figure. 583 00:31:40,520 --> 00:31:44,375 As he passes the back of the car, he's quite a tall person, 584 00:31:44,400 --> 00:31:50,655 and as he moves, you can see his stride is actually quite long. 585 00:31:50,680 --> 00:31:52,575 Due to the figure's size and movements, 586 00:31:52,600 --> 00:31:54,775 Ashley is sure that 587 00:31:54,800 --> 00:31:58,415 neither of the figures is the owner of the car or the 16-year-old. 588 00:31:58,440 --> 00:32:01,615 I was confident I was dealing with the same individual, 589 00:32:01,640 --> 00:32:03,375 Svenson. 590 00:32:03,400 --> 00:32:06,695 Ashley's evidence confirms Ong-A-Kwie was at the park 591 00:32:06,720 --> 00:32:09,895 moments beforejodie was murdered. 592 00:32:09,920 --> 00:32:13,175 And police believe he is one of the figures seen running back to the car 593 00:32:13,200 --> 00:32:15,695 minutes afterjodie was attacked. 594 00:32:16,880 --> 00:32:18,255 The following day, 595 00:32:18,280 --> 00:32:25,055 he's captured returning home, but this time, the coat is missing. 596 00:32:25,080 --> 00:32:30,295 After extensive searches at his address, it's not found. 597 00:32:30,320 --> 00:32:32,455 The fact that they weren't able to locate the coat 598 00:32:32,480 --> 00:32:33,495 with the fur-lined hood 599 00:32:33,520 --> 00:32:36,135 that a witness had seen the offender wearing 600 00:32:36,160 --> 00:32:39,095 tends to suggest that the offender might have known 601 00:32:39,120 --> 00:32:42,415 that they'd been seen and they've discarded the clothing somewhere. 602 00:32:42,440 --> 00:32:46,455 Obviously reduces the likelihood of being able to find some evidence, 603 00:32:46,480 --> 00:32:49,735 but it doesn't reduce the effort that is put in by the police 604 00:32:49,760 --> 00:32:51,575 to try and recover evidence. 605 00:32:51,600 --> 00:32:53,895 The police will never give up because we need to find 606 00:32:53,920 --> 00:32:56,335 a trace of the killer at the crime scene. 607 00:32:56,360 --> 00:33:00,895 At the lab, scientists have the results from the seized knives. 608 00:33:00,920 --> 00:33:04,975 One of the knives fit the profile as described by the pathologist, 609 00:33:05,000 --> 00:33:07,575 but there was no forensic evidence on that knife. 610 00:33:07,600 --> 00:33:10,215 That doesn't mean to say that wasn't the murder weapon. 611 00:33:10,240 --> 00:33:14,095 That might be because the offender had cleaned the knife. 612 00:33:14,120 --> 00:33:16,455 It doesn't mean to say it wasn't linked to the offence, 613 00:33:16,480 --> 00:33:19,095 it's just we can't forensically prove that. 614 00:33:19,120 --> 00:33:22,335 But it does tell you something about the offender, 615 00:33:22,360 --> 00:33:25,695 the fact that he's got two knives hidden in his bedroom 616 00:33:25,720 --> 00:33:29,015 indicates that he's probably linked to 617 00:33:29,040 --> 00:33:32,615 potentially some serious of fences or threats. 618 00:33:32,640 --> 00:33:36,095 To prove Ong-A-Kwie is responsible for killing Jodie, 619 00:33:36,120 --> 00:33:39,575 police need to show intent. 620 00:33:39,600 --> 00:33:43,295 Forensic image expert Ashley makes a breakthrough. 621 00:33:43,320 --> 00:33:47,015 Video footage is made up of individual still images 622 00:33:47,040 --> 00:33:48,655 and they run at a sequence. 623 00:33:48,680 --> 00:33:51,775 You have to ensure that you've seen every image. 624 00:33:51,800 --> 00:33:55,455 I'm looking at the taller figure. Svenson. 625 00:33:55,480 --> 00:33:58,015 The second person who's coming across, 626 00:33:58,040 --> 00:34:02,455 and I noticed a very short duration bright return. 627 00:34:02,480 --> 00:34:05,135 The glint. 628 00:34:05,160 --> 00:34:10,495 This glint is appearing around about waist level on the figure, 629 00:34:10,520 --> 00:34:14,135 so whatever this is is extending beyond his hand 630 00:34:14,160 --> 00:34:18,495 sufficiently to capture enough light to give you that glint. 631 00:34:18,520 --> 00:34:21,335 From the work I've clone over the last 30 years, 632 00:34:21,360 --> 00:34:25,295 this is absolutely consistent with a bladed item. 633 00:34:25,320 --> 00:34:29,175 The CCTV evidence is really good because it does place a suspect 634 00:34:29,200 --> 00:34:30,695 at the crime scene, 635 00:34:30,720 --> 00:34:33,095 and it also potentially shows that they are armed, 636 00:34:33,120 --> 00:34:37,055 so therefore the intent was there to commit some kind of offence 637 00:34:37,080 --> 00:34:39,255 or threaten someone with a bladed item. 638 00:34:39,280 --> 00:34:43,895 Police now have enough evidence to charge Svenson Ong-A-Kwie 639 00:34:43,920 --> 00:34:46,535 with the murder ofjodie Chesney. 640 00:34:46,560 --> 00:34:50,055 The information they got form just one small piece 641 00:34:50,080 --> 00:34:52,735 was just outstanding. 642 00:34:52,760 --> 00:34:54,535 It was a relief when they were charged 643 00:34:54,560 --> 00:34:58,775 but we still didn't have any answers as to why it had happened. 644 00:34:58,800 --> 00:35:03,535 With no incriminating evidence to link Aaron Isaacs to the murder, 645 00:35:03,560 --> 00:35:05,855 he's released on bail. 646 00:35:05,880 --> 00:35:09,655 Police still need to identify Svenson Ong-A-Kwie's accomplice. 647 00:35:10,960 --> 00:35:15,615 On the morning of the murder, CCTV shows he had a visitor to his home. 648 00:35:15,640 --> 00:35:18,095 One of the clips that I was presented with 649 00:35:18,120 --> 00:35:23,735 was a daytime piece of footage of a person approaching the premises, 650 00:35:23,760 --> 00:35:29,095 and you can see as he approaches, he's wearing a hat under his hood, 651 00:35:29,120 --> 00:35:33,535 and on the hat there are two dark items 652 00:35:33,560 --> 00:35:36,695 which look like a pair of ski goggles. 653 00:35:36,720 --> 00:35:41,775 Police intelligence shows Isaacs is in the same gang as Ong-A-Kwi, 654 00:35:41,800 --> 00:35:44,095 recruited as the gang's drug runner 655 00:35:44,120 --> 00:35:46,055 shortly after he was taken into care. 656 00:35:47,360 --> 00:35:50,455 He has prior convictions for actual bodily harm, 657 00:35:50,480 --> 00:35:54,415 possessing a pointed article and possession of a knife. 658 00:35:54,440 --> 00:35:59,495 Ashley looks for sightings of Isaacs from the night ofjodie's murder. 659 00:35:59,520 --> 00:36:02,775 You see two figures arriving from the top of the image. 660 00:36:02,800 --> 00:36:07,535 The taller of the two figures is Svenson. 661 00:36:07,560 --> 00:36:10,095 In the case of the shorter figure, 662 00:36:10,120 --> 00:36:13,655 it's clear that he has something on his hat. 663 00:36:13,680 --> 00:36:17,855 This object in fact is a pair of objects, 664 00:36:17,880 --> 00:36:19,455 appear dark in some of the imagery, 665 00:36:19,480 --> 00:36:22,615 and it appears light in others depending on the lighting 666 00:36:22,640 --> 00:36:25,215 and how it's angled towards the camera. 667 00:36:25,240 --> 00:36:30,135 This is consistent with a pair of goggles on the top of a hat. 668 00:36:30,160 --> 00:36:34,695 I have no doubt I'm dealing with the same person, Aaron Isaacs. 669 00:36:34,720 --> 00:36:39,135 Ashley can confirm Aaron Isaacs was wearing the distinctive headgear 670 00:36:39,160 --> 00:36:42,655 an hour beforejodie was stabbed. 671 00:36:42,680 --> 00:36:46,335 He looks at the poorer quality CCTV again 672 00:36:46,360 --> 00:36:49,495 of Ong-A-Kwie and the second figure walking towards the park 673 00:36:49,520 --> 00:36:52,255 just moments before the attack. 674 00:36:52,280 --> 00:36:56,775 If I start to look at the head of the shorter figure, 675 00:36:56,800 --> 00:36:59,215 I can see a very bright return. 676 00:36:59,240 --> 00:37:04,295 This is something reflecting so that figure's wearing headgear 677 00:37:04,320 --> 00:37:08,335 with some feature that reflects light. 678 00:37:08,360 --> 00:37:14,815 This figure is showing the same features in relative size, 679 00:37:14,840 --> 00:37:20,815 dark clothing ancl the headgear as Aaron Isaacs. 680 00:37:20,840 --> 00:37:25,055 Police now have all they need to charge their fourth suspect, 681 00:37:25,080 --> 00:37:28,615 Aaron Isaacs, with the murder ofjodie Chesney. 682 00:37:36,040 --> 00:37:41,215 Police have charged four suspects with the murder ofjodie Chesney. 683 00:37:41,240 --> 00:37:46,015 The driver of a Corsa seen at the crime scene and a 16-year-old 684 00:37:46,040 --> 00:37:50,335 both admit being in the car, but insist they're not involved. 685 00:37:50,360 --> 00:37:55,135 The other two suspects, Svenson Ong-A-Kwie and Aaron Isaacs 686 00:37:55,160 --> 00:37:57,815 also plead not guilty. 687 00:37:57,840 --> 00:38:02,655 They've been forensically identified on CCTV as entering the park 688 00:38:02,680 --> 00:38:07,975 moments before the murder, and there's evidence they were armed. 689 00:38:08,000 --> 00:38:13,455 Six months later, the country's media is outside the Old Bailey 690 00:38:13,480 --> 00:38:17,215 as jodie's friends and family prepare themselves for trial. 691 00:38:19,160 --> 00:38:21,375 The Old Bailey itself is a very daunting building, 692 00:38:21,400 --> 00:38:24,335 and I was sat in the public gallery, 693 00:38:24,360 --> 00:38:28,575 so not only was I overlooking the whole thing, 694 00:38:28,600 --> 00:38:31,295 I had their friends and family sitting with me as well, 695 00:38:31,320 --> 00:38:33,375 which is hard. 696 00:38:33,400 --> 00:38:38,255 That is then when justice kind of starts to begin for that family. 697 00:38:38,280 --> 00:38:40,455 Something's gonna happen now. 698 00:38:40,480 --> 00:38:42,735 What's the chance of us getting a conviction out of this? 699 00:38:43,920 --> 00:38:47,775 The investigation team will need to bring together everything they can. 700 00:38:47,800 --> 00:38:49,175 Anything short of that 701 00:38:49,200 --> 00:38:51,775 and they'll be not guilty, so that's a lot of pressure. 702 00:38:51,800 --> 00:38:55,335 So what they'll do is they'll bring in all the different strands. 703 00:38:55,360 --> 00:39:00,015 They'll bring in CCTV, forensics, witnesses, phones, 704 00:39:00,040 --> 00:39:03,695 even past criminal behaviour can be brought in 705 00:39:03,720 --> 00:39:05,495 if it's relevant to the charge. 706 00:39:05,520 --> 00:39:08,055 All these small little strands on their own might not be much, 707 00:39:08,080 --> 00:39:10,255 but when they're put together, 708 00:39:10,280 --> 00:39:13,855 they can build a picture that will help the jury make their decision. 709 00:39:15,160 --> 00:39:17,375 The question now is which of the teens 710 00:39:17,400 --> 00:39:20,655 is responsible for stabbing Jodie? 711 00:39:20,680 --> 00:39:24,255 It's hard to say what you feel when you first see them, 712 00:39:24,280 --> 00:39:27,175 and they-they wouldn't make eye contact with us. 713 00:39:27,200 --> 00:39:29,655 We didn't wanna make eye contact with them, but... 714 00:39:29,680 --> 00:39:32,815 The youngest one spent a lot of time at the trial 715 00:39:32,840 --> 00:39:36,255 not really paying attention to what was going on. 716 00:39:36,280 --> 00:39:39,375 He was laughing and joking, and... 717 00:39:39,400 --> 00:39:42,895 it's hard to see that you were involved in killing my child 718 00:39:42,920 --> 00:39:44,935 and you think it's a joke. 719 00:39:44,960 --> 00:39:48,975 Faced with the digital and CCTV evidence, 720 00:39:49,000 --> 00:39:52,175 Svenson Ong-A-Kwie and Aaron Isaacs 721 00:39:52,200 --> 00:39:55,975 admit that they are the men seen entering the park, 722 00:39:56,000 --> 00:39:59,855 but each insist they did not deliver the fatal blow. 723 00:40:01,400 --> 00:40:04,255 Having them blame each other was almost like they didn't care 724 00:40:04,280 --> 00:40:05,735 what they had clone, 725 00:40:05,760 --> 00:40:08,935 all they wanted to do was get away with it, basically. 726 00:40:08,960 --> 00:40:11,455 They didn't care what the consequences were, 727 00:40:11,480 --> 00:40:15,775 they just didn't wanna face up to the fact that they were to blame. 728 00:40:15,800 --> 00:40:17,415 When the evidence is strong enough 729 00:40:17,440 --> 00:40:22,575 to place more than one person at a scene, loyalty goes out the window. 730 00:40:22,600 --> 00:40:26,815 People have got self-interest and people turn on each other. 731 00:40:26,840 --> 00:40:29,015 We often call this a cutthroat defence... 732 00:40:29,040 --> 00:40:33,255 which can be interesting dynamics for a murder trial 733 00:40:33,280 --> 00:40:35,735 and quite often it brings into play evidence 734 00:40:35,760 --> 00:40:38,975 that the prosecution themselves wouldn't be able to bring out, 735 00:40:39,000 --> 00:40:40,295 what's known as bad character. 736 00:40:42,320 --> 00:40:44,895 In an attempt to incriminate each other, 737 00:40:44,920 --> 00:40:48,575 both teenagers bring up a violent event they were involved in 738 00:40:48,600 --> 00:40:50,775 against a rival gang, 739 00:40:50,800 --> 00:40:54,415 which left Ong-A-Kwie with a stab wound to his thigh. 740 00:40:55,920 --> 00:40:59,255 The prosecution says the footage encapsulates 741 00:40:59,280 --> 00:41:02,815 the suspects' casual world of violence. 742 00:41:02,840 --> 00:41:05,215 It was senseless violence. 743 00:41:05,240 --> 00:41:08,415 People were using knives and not thinking twice about it. 744 00:41:08,440 --> 00:41:09,855 That was at the time, I think, 745 00:41:09,880 --> 00:41:13,095 reflective of a lot of that crime that was going on in London. 746 00:41:13,120 --> 00:41:19,095 The prosecution enter a covertly recorded prison visit into evidence. 747 00:41:19,120 --> 00:41:21,775 The driver of the car tells his visitors 748 00:41:21,800 --> 00:41:26,375 that he did break the law drug dealing, but did not commit murder. 749 00:41:27,920 --> 00:41:31,215 He confesses that the two teenagers that enter the park 750 00:41:31,240 --> 00:41:35,375 went there looking for revenge for Ong-A-Kwie's previous stab wound. 751 00:41:37,080 --> 00:41:40,815 The rival gang were known to hang out in the park, 752 00:41:40,840 --> 00:41:42,575 but in the darkness, 753 00:41:42,600 --> 00:41:45,495 the teen stabbed innocentjodie Chesney 754 00:41:45,520 --> 00:41:47,855 in a case of mistaken identity. 755 00:41:50,400 --> 00:41:52,855 When you investigate murders, 756 00:41:52,880 --> 00:41:56,455 one of the tricks is try and get yourself in the mind of the killer. 757 00:41:56,480 --> 00:41:59,855 Why did they do what they did?
