Police Emergency, what's your emergency? 2 00:00:04,041 --> 00:00:06,321 NEWSREADER: A murder investigation is continuing in Luton after 3 00:00:06,321 --> 00:00:09,561 a woman was killed at a house in Overstone Road on Monday night. 4 00:00:09,561 --> 00:00:12,001 Is it possible to get away with murder? 5 00:00:12,961 --> 00:00:15,081 What does a killer do after committing 6 00:00:15,081 --> 00:00:16,721 the most heinous of crimes? 7 00:00:17,481 --> 00:00:20,961 MAN: This was a cold, calculating, callous murder. 8 00:00:20,961 --> 00:00:24,881 Do they carry on as normal and hide in plain sight? 9 00:00:26,281 --> 00:00:27,721 Or go on the run? 10 00:00:28,921 --> 00:00:31,121 MAN: It's sobering that something so terrible 11 00:00:31,121 --> 00:00:33,281 has gone on within a normal house. 12 00:00:34,321 --> 00:00:38,281 How do the actions of a killer after their crime 13 00:00:38,281 --> 00:00:41,121 influence the police investigation? 14 00:00:41,121 --> 00:00:43,401 NEWSREADER: Police are still at the home of a woman from Luton 15 00:00:43,401 --> 00:00:45,241 who was murdered on Monday evening. 16 00:00:48,561 --> 00:00:50,961 NEWSREADER: Her family have paid tribute to a loving mother 17 00:00:50,961 --> 00:00:52,881 to four beautiful children. 18 00:00:52,881 --> 00:00:57,961 By focusing on the aftermath, we unpick the mindset of a killer, 19 00:00:59,961 --> 00:01:02,961 understand the motive and reveal 20 00:01:03,681 --> 00:01:05,281 what the killer did next. 21 00:01:24,601 --> 00:01:29,041 NARRATOR: 26-year-old Saima Khan and her 18 year-old sister, Sabah, 22 00:01:29,041 --> 00:01:32,601 move from Holland to this street with their parents and two brothers. 23 00:01:35,961 --> 00:01:39,761 Saima Khan's family seemed the very image of a respectable family 24 00:01:39,761 --> 00:01:42,041 that lived in the suburbs. 25 00:01:42,041 --> 00:01:44,121 They all had jobs, both Saima 26 00:01:44,121 --> 00:01:46,321 and her sister worked as carers, 27 00:01:46,321 --> 00:01:49,681 and they all seemed to be upstanding members of the community. 28 00:01:49,681 --> 00:01:53,681 It's just the normal, run-of-the-mill street, 29 00:01:53,681 --> 00:01:55,641 I would say. 30 00:01:55,641 --> 00:01:58,001 You know, people live how they live. 31 00:02:00,761 --> 00:02:03,881 It's a very suburban area, very family oriented, 32 00:02:03,881 --> 00:02:07,641 so certainly, there's never been any major crime that I know of. 33 00:02:07,641 --> 00:02:12,161 NARRATOR: The two sisters soon settled in to their new life. 34 00:02:12,161 --> 00:02:13,921 The two were inseparable. 35 00:02:13,921 --> 00:02:16,401 In fact, Sabah described the way in which they 36 00:02:16,401 --> 00:02:19,241 interacted with each other as being so close 37 00:02:19,241 --> 00:02:22,681 that she felt it was one soul divided into two bodies. 38 00:02:22,681 --> 00:02:24,281 You could tell they were close, obviously, 39 00:02:24,281 --> 00:02:26,801 'cause wherever they would go, they would go together anyway. 40 00:02:31,521 --> 00:02:33,961 Saima Khan marries Hafeez 41 00:02:33,961 --> 00:02:36,481 and he moves into the happy family home in Luton. 42 00:02:37,561 --> 00:02:40,401 Saima and Hafeez go on to have four children. 43 00:02:40,401 --> 00:02:45,401 For the inseparable sisters, this was a challenging change 44 00:02:45,401 --> 00:02:47,001 in the family dynamic. 45 00:02:49,401 --> 00:02:51,121 The tale of two sisters, 46 00:02:51,121 --> 00:02:54,121 one of whom was married and had children 47 00:02:54,121 --> 00:02:56,841 and had the perfect family life. 48 00:02:56,841 --> 00:03:00,121 And the other was the younger sister who 49 00:03:00,121 --> 00:03:02,281 lived more or less in her shadow. 50 00:03:02,281 --> 00:03:07,681 NARRATOR: But in 2016, everything for this family was to change. 51 00:03:11,401 --> 00:03:17,561 It was otherwise an ordinary day in the life of that family. 52 00:03:17,561 --> 00:03:20,921 Saima was due to go out and work as a carer, 53 00:03:20,921 --> 00:03:23,321 which was her part-time job. 54 00:03:23,321 --> 00:03:25,281 Sabah, as always, 55 00:03:25,281 --> 00:03:28,921 would be looking after her nephews and nieces back in the house. 56 00:03:31,281 --> 00:03:36,801 Just before 11:00, Sabah sent four text messages 57 00:03:36,801 --> 00:03:41,961 to Saima Khan, telling her that one of the children was crying 58 00:03:41,961 --> 00:03:45,321 and she should come home as soon as possible. 59 00:03:46,441 --> 00:03:49,281 NARRATOR: Saima responds to her sister's call 60 00:03:49,281 --> 00:03:51,441 and returns home to her children. 61 00:03:51,441 --> 00:03:54,801 Her car pulls into the driveway at 11:07pm. 62 00:03:54,801 --> 00:03:59,561 A neighbour's CCTV camera picks up the moment she enters the house. 63 00:04:03,881 --> 00:04:08,721 But as Saima Khan enters her home, the unthinkable happens. 64 00:04:08,721 --> 00:04:11,161 She is attacked in her hallway, 65 00:04:12,161 --> 00:04:15,881 stabbed and left to die. 66 00:04:18,001 --> 00:04:19,241 NEWSREADER: A woman was killed 67 00:04:19,241 --> 00:04:21,241 at a house in Overstone Road on Monday night. 68 00:04:21,241 --> 00:04:24,641 She's been named locally as 34-year-old Saima Khan, 69 00:04:24,641 --> 00:04:26,401 a mother of four young children. 70 00:04:28,441 --> 00:04:32,721 The killing was ferocious. 71 00:04:32,721 --> 00:04:34,881 It was awful. 72 00:04:34,881 --> 00:04:40,361 There were 68 strikes with a knife. 73 00:04:40,361 --> 00:04:43,161 Some of the injuries were so severe 74 00:04:43,161 --> 00:04:47,841 that Saima nearly lost a hand and her head was nearly cut off. 75 00:04:49,801 --> 00:04:53,441 I was watching telly and you heard all this screaming, 76 00:04:53,441 --> 00:04:59,441 but the sound of the screaming was like a blood-curdling sort of thing. 77 00:04:59,441 --> 00:05:03,321 You know, that's the sound that I got in my head. 78 00:05:03,321 --> 00:05:08,281 I knew that something awful had happened. 79 00:05:11,001 --> 00:05:13,561 NARRATOR: When police arrive at the scene, 80 00:05:13,561 --> 00:05:16,601 they are met by Saima's sister, Sabah, 81 00:05:16,601 --> 00:05:19,241 who tragically came across her sister's body. 82 00:05:20,641 --> 00:05:23,721 They were met with a scene of complete carnage. 83 00:05:23,721 --> 00:05:27,081 This was an ordinary, humble family home, 84 00:05:27,081 --> 00:05:31,681 in which in the hallway was lying the body of a woman. 85 00:05:31,681 --> 00:05:34,161 There was blood everywhere. 86 00:05:34,161 --> 00:05:37,441 So much blood that it was almost like a river. 87 00:05:37,441 --> 00:05:41,641 The police body cameras record everything Sabah says 88 00:05:41,641 --> 00:05:45,321 following her discovery of her sister in the hallway. 89 00:06:47,441 --> 00:06:53,281 Sabah Khan told police that she had been upstairs in the shower, 90 00:06:53,281 --> 00:06:55,081 heard a bang, come downstairs 91 00:06:55,081 --> 00:06:59,841 and found her sister in the hallway, very badly injured. 92 00:07:01,281 --> 00:07:04,881 She assumed that there had been an intruder 93 00:07:04,881 --> 00:07:07,721 and it was a burglary gone wrong. 94 00:07:07,721 --> 00:07:12,721 NARRATOR: Rumours of a burglary escalate through the community. 95 00:07:12,721 --> 00:07:14,361 REPORTER: On this side of the house, 96 00:07:14,361 --> 00:07:18,441 there's also a side door with quite a lot of the glass missing, 97 00:07:18,441 --> 00:07:21,161 leading people to speculate that that might have been 98 00:07:21,161 --> 00:07:24,721 how a suspected burglar may have gained access to the house. 99 00:07:24,721 --> 00:07:27,041 We did feel very scared. I used to double-lock the door anyway, 100 00:07:27,041 --> 00:07:30,561 thinking at any time, anybody could come in. 101 00:07:30,561 --> 00:07:33,721 And I was afraid to be home alone anyway. 102 00:07:33,721 --> 00:07:38,361 There was a great deal of fear among people 103 00:07:38,361 --> 00:07:42,281 locally because, as the story was at the time, this was a lady who'd 104 00:07:42,281 --> 00:07:48,041 returned home to her house to see her children and had succumbed to 105 00:07:48,041 --> 00:07:49,681 a fairly horrific death. 106 00:07:56,681 --> 00:08:00,521 A community shaken to the core by a brutal murder. 107 00:08:00,521 --> 00:08:04,441 As police scramble to make sense of the immediate facts, 108 00:08:04,441 --> 00:08:06,241 where is the killer? 109 00:08:06,241 --> 00:08:08,441 What are they doing in these vital moments, 110 00:08:08,441 --> 00:08:11,441 having just killed Saima so savagely? 111 00:08:11,441 --> 00:08:13,761 Have they fled the scene? 112 00:08:13,761 --> 00:08:16,281 Or are they closer than you think? 113 00:08:26,781 --> 00:08:30,541 34-year-old mother-of-four Saima Khan from Luton 114 00:08:30,541 --> 00:08:33,101 has been stabbed on her doorstep. 115 00:08:33,101 --> 00:08:36,341 Inside the house is her beloved sister, Sabah. 116 00:08:36,341 --> 00:08:38,981 As police arrive on the scene, 117 00:08:38,981 --> 00:08:42,901 she reveals that she has come downstairs to discover 118 00:08:42,901 --> 00:08:44,821 her sister dying. 119 00:09:00,981 --> 00:09:03,381 NEWSREADER: The murder investigation is continuing in Luton 120 00:09:03,381 --> 00:09:04,541 after a woman was killed. 121 00:09:04,541 --> 00:09:07,261 Neighbours say she was the victim of a botched burglary. 122 00:09:07,261 --> 00:09:10,421 REPORTER: There's also, on this side of the house, 123 00:09:10,421 --> 00:09:13,181 a side door with quite a lot of the glass missing, 124 00:09:13,181 --> 00:09:14,901 leading people to speculate 125 00:09:14,901 --> 00:09:18,101 that that might have been how a suspected burglar may have 126 00:09:18,101 --> 00:09:20,061 gained access to the house. 127 00:09:20,061 --> 00:09:25,061 Faced with a broken window pane and a seemingly surprise attack 128 00:09:25,061 --> 00:09:27,981 carried out to such a ferocious extent, 129 00:09:27,981 --> 00:09:32,821 is this a burglary gone wrong, or something more sinister? 130 00:09:33,781 --> 00:09:38,621 After such a brutal crime, the question police need to answer 131 00:09:38,621 --> 00:09:40,781 is, "What does a killer do next?" 132 00:09:41,981 --> 00:09:45,341 NARRATOR: This is where police use expert criminologists 133 00:09:45,341 --> 00:09:49,341 to get into the mind of a killer, and determine their next move. 134 00:09:49,341 --> 00:09:53,701 My name's Dr Jane Monckton-Smith and I'm a forensic criminologist. 135 00:09:53,701 --> 00:09:57,061 In the very early stages of any investigation, 136 00:09:57,061 --> 00:10:00,701 we can look at patterns and behaviours of killers, 137 00:10:00,701 --> 00:10:03,181 to try and find out what the motivation is. 138 00:10:11,541 --> 00:10:14,141 NARRATOR: Overstone Road in Luton is now a crime scene 139 00:10:14,141 --> 00:10:17,141 and the family are moved to a property nearby 140 00:10:17,141 --> 00:10:20,581 so a thorough forensic search of the family home can begin. 141 00:10:22,981 --> 00:10:26,261 So, I got a phone call from the news desk 142 00:10:26,261 --> 00:10:29,781 just telling me that there had been a death 143 00:10:29,781 --> 00:10:34,981 as a result of what we thought was a bungled robbery at the time. 144 00:10:34,981 --> 00:10:38,821 This was a road I'd driven past so many times. 145 00:10:38,821 --> 00:10:43,341 But when I got here on that day, it was totally transformed. 146 00:10:43,341 --> 00:10:46,541 There were police cars everywhere, stretching up the road. 147 00:10:46,541 --> 00:10:51,901 The police cordon started probably a few yards up the road. 148 00:10:51,901 --> 00:10:56,061 For the police, time is now of the essence. 149 00:10:56,981 --> 00:10:59,621 The first 60 minutes of the investigation, 150 00:10:59,621 --> 00:11:01,621 and indeed, the first 24 hours, 151 00:11:01,621 --> 00:11:03,461 are the golden hours for us 152 00:11:03,461 --> 00:11:08,621 because we know the suspect will likely go home, change clothes, 153 00:11:08,621 --> 00:11:09,981 wash and shave and shower. 154 00:11:09,981 --> 00:11:11,781 And then we've lost some of the forensic evidence. 155 00:11:11,781 --> 00:11:15,621 First port of call is to seal the place off, cordon it. 156 00:11:15,621 --> 00:11:18,621 Only people go in there wearing protective clothes 157 00:11:18,621 --> 00:11:21,061 and protective shoes and gloves. 158 00:11:21,061 --> 00:11:22,621 And then we'll have an examination, 159 00:11:22,621 --> 00:11:25,701 looking first for any murder weapon. 160 00:11:25,701 --> 00:11:29,421 With forensic teams carrying out a fingertip search of the house, 161 00:11:29,421 --> 00:11:32,181 others comb the neighbourhood. 162 00:11:32,181 --> 00:11:33,821 It was just eerie, you know? 163 00:11:33,821 --> 00:11:37,901 There was a very still quietness about the road. 164 00:11:39,901 --> 00:11:44,421 Police knocked at the door and asked us if we'd seen anything 165 00:11:44,421 --> 00:11:47,701 or anybody down the garden or, "Had you heard anything?" 166 00:11:47,701 --> 00:11:50,581 Then everything was cordoned off, as well. 167 00:11:50,581 --> 00:11:53,181 From then onwards, they started the investigation, I think. 168 00:11:53,181 --> 00:11:54,901 That's the forensic team, like you said, 169 00:11:54,901 --> 00:11:57,981 every day, throughout the whole week, basically, you know. 170 00:11:57,981 --> 00:11:59,341 Doing the investigations 171 00:11:59,341 --> 00:12:01,821 in the garden, on the road, everywhere, they were doing. 172 00:12:11,621 --> 00:12:15,341 Two days later and the police have no murder weapon, 173 00:12:15,341 --> 00:12:18,221 no motive and no suspect. 174 00:12:18,221 --> 00:12:21,781 What they do have is a body. 175 00:12:21,781 --> 00:12:26,061 And the post-mortem results provide crucial evidence. 176 00:12:26,061 --> 00:12:29,181 Post-mortem is critical because 177 00:12:29,181 --> 00:12:31,261 it will prove that you have a murder. 178 00:12:31,261 --> 00:12:33,501 It should be able to tell you the size of the knife 179 00:12:33,501 --> 00:12:34,901 from the wounds, by measuring it. 180 00:12:34,901 --> 00:12:36,461 So when you come out of the post-mortem, 181 00:12:36,461 --> 00:12:38,061 you know you've definitely got a murder, 182 00:12:38,061 --> 00:12:39,621 you know she definitely died 183 00:12:39,621 --> 00:12:41,901 by however many knife wounds there were. 184 00:12:41,901 --> 00:12:43,581 It gives a profile. 185 00:12:44,821 --> 00:12:50,781 That kind of violence, that comes from an almost unearthly rage. 186 00:12:54,181 --> 00:12:58,781 Rumours start to spread that this is not all as it seems. 187 00:12:58,781 --> 00:13:02,461 It's difficult to understand why a burglar would see someone like 188 00:13:02,461 --> 00:13:07,461 Saima Khan as such a threat that she had to be murdered, 189 00:13:07,461 --> 00:13:09,261 and not just murdered, 190 00:13:09,261 --> 00:13:13,341 stabbed repeatedly with such ferocity 191 00:13:13,341 --> 00:13:16,021 that her neck was practically severed, 192 00:13:16,021 --> 00:13:18,021 unless he was a raving lunatic. 193 00:13:18,021 --> 00:13:21,461 It's hard to imagine how an intruder, 194 00:13:21,461 --> 00:13:24,421 or why an intruder would have carried out 195 00:13:24,421 --> 00:13:26,381 that particular kind of attack. 196 00:13:29,981 --> 00:13:32,621 Suddenly, the police have a new focus. 197 00:13:32,621 --> 00:13:35,501 This is not necessarily a burglary gone wrong. 198 00:13:35,501 --> 00:13:39,541 The post-mortem results point towards frenzied violence, 199 00:13:39,541 --> 00:13:42,261 more characteristic of a crime of passion. 200 00:13:43,821 --> 00:13:47,541 Murders in botched burglaries are incredibly rare, 201 00:13:47,541 --> 00:13:50,541 and there is no reason in that scenario 202 00:13:50,541 --> 00:13:53,461 for somebody to be incredibly angry. 203 00:13:54,501 --> 00:13:56,741 There was a change in the air. 204 00:13:56,741 --> 00:13:59,381 There was a change of feeling in the community. 205 00:13:59,381 --> 00:14:04,541 The kind of injuries, which we were hearing that Saima had experienced, 206 00:14:04,541 --> 00:14:06,061 were not the kind of injuries 207 00:14:06,061 --> 00:14:08,621 you would expect in those circumstances. 208 00:14:09,501 --> 00:14:12,461 NARRATOR: As the person who discovered the body, 209 00:14:12,461 --> 00:14:14,861 police need to interview sister Sabah, 210 00:14:14,861 --> 00:14:17,581 as her account could hold the key to the case. 211 00:14:19,341 --> 00:14:22,501 Sabah's police interview is consistent with her story 212 00:14:22,501 --> 00:14:24,061 of a possible intruder. 213 00:14:25,461 --> 00:14:28,741 She told the police she was in the shower 214 00:14:28,741 --> 00:14:31,221 when her sister returned home. 215 00:14:31,221 --> 00:14:35,941 She heard a bang, I think, and she came downstairs 216 00:14:35,941 --> 00:14:39,421 and she found her in the hallway, in a pool of blood. 217 00:14:40,261 --> 00:14:44,981 And she assumed that it had been a burglar or an intruder 218 00:14:44,981 --> 00:14:49,541 or something like that because the back door had been smashed in. 219 00:14:51,781 --> 00:14:54,421 The police would have wanted to know 220 00:14:54,421 --> 00:14:57,141 everything about Saima's private life 221 00:14:57,141 --> 00:15:00,181 and, of course, Sabah would have been a person 222 00:15:00,181 --> 00:15:03,181 who could give that kind of information. 223 00:15:06,261 --> 00:15:09,261 Sabah also offers police some vital information 224 00:15:09,261 --> 00:15:11,581 about sister Saima's personal life - 225 00:15:11,581 --> 00:15:14,621 that her sister was having an affair. 226 00:15:14,621 --> 00:15:17,701 During the interview with the police, 227 00:15:17,701 --> 00:15:21,101 Sabah said that she had overheard a conversation 228 00:15:21,101 --> 00:15:24,141 between her sister and her sister's lover, 229 00:15:24,141 --> 00:15:25,661 where he had threatened her. 230 00:15:27,941 --> 00:15:30,781 So police would have looked at the husband 231 00:15:30,781 --> 00:15:35,541 because that would have been the more obvious suspect. 232 00:15:35,541 --> 00:15:41,101 And if Saima Khan had been having an affair, like her sister said, 233 00:15:41,101 --> 00:15:45,501 it would have certainly given him a reason to have killed her. 234 00:15:47,261 --> 00:15:49,581 In this kind of situation, 235 00:15:49,581 --> 00:15:54,501 the most likely person to have murdered Saima would be her husband. 236 00:15:54,501 --> 00:15:57,901 That's just a statistical likelihood. 237 00:15:57,901 --> 00:16:00,261 So they would definitely have been looking at him. 238 00:16:01,501 --> 00:16:05,461 Police trawl through the family computers looking for clues. 239 00:16:05,461 --> 00:16:10,701 And what they soon discover turns the investigation on its head. 240 00:16:12,301 --> 00:16:14,141 It wasn't Saima having an affair. 241 00:16:14,141 --> 00:16:16,421 It was Hafeez. 242 00:16:16,421 --> 00:16:19,941 Police hone in on Hafeez's internet activities. 243 00:16:19,941 --> 00:16:22,381 In any investigation, anybody who you think 244 00:16:22,381 --> 00:16:24,141 is a potential suspect, 245 00:16:24,141 --> 00:16:26,941 then you will start looking at their use of IT. 246 00:16:26,941 --> 00:16:30,661 Telephones, computers, laptops, iPads. 247 00:16:30,661 --> 00:16:35,781 In this day and age, everyone leaves a digital footprint. 248 00:16:35,781 --> 00:16:38,981 The examination of the family computers is a game-changer. 249 00:16:40,141 --> 00:16:42,341 Someone wanted Saima Khan dead. 250 00:16:49,021 --> 00:16:52,341 On the internet searches, they found how you could kill somebody, 251 00:16:52,341 --> 00:16:55,181 how you could poison them, how you could overdose with drugs. 252 00:16:55,181 --> 00:16:58,261 When forensic investigators delve deeper, 253 00:16:58,261 --> 00:17:00,901 they discover something else. 254 00:17:00,901 --> 00:17:04,781 It isn't Hafeez who has been making these searches. 255 00:17:06,301 --> 00:17:08,421 It's Sabah. 256 00:17:08,421 --> 00:17:10,941 She started internet searches, 257 00:17:10,941 --> 00:17:14,821 looking at ways of poisoning someone, ways of killing someone. 258 00:17:14,821 --> 00:17:17,261 She hired somebody in Pakistan, 259 00:17:17,261 --> 00:17:20,821 who was one of these priests who dealt in the black arts, 260 00:17:20,821 --> 00:17:25,021 and asked him to cast a spell on her sister, Saima, 261 00:17:25,021 --> 00:17:26,821 to see if that would get rid of her. 262 00:17:26,821 --> 00:17:29,181 We know that she had engaged the services 263 00:17:29,181 --> 00:17:32,861 of a mysterious character called 'The Fixer' in Pakistan. 264 00:17:32,861 --> 00:17:37,781 She had paid him 5,000 pounds and asked him to kill her sister. 265 00:17:38,781 --> 00:17:43,501 In fact, Sabah Khan's internet records revealed that, for months, 266 00:17:43,501 --> 00:17:47,061 she's been searching ways to kill someone and not get caught. 267 00:17:49,021 --> 00:17:50,621 WOMAN: Sabah Khan, 268 00:17:50,621 --> 00:17:55,181 she'd done Google searches for ways of killing people - 269 00:17:55,181 --> 00:18:01,741 poisons, poisonous snakes, drugs - 270 00:18:01,741 --> 00:18:03,741 all sorts of different ways 271 00:18:03,741 --> 00:18:07,781 and how to commit a perfect murder and get away with it. 272 00:18:07,781 --> 00:18:09,621 Sabah has been planning her sister's murder, 273 00:18:09,621 --> 00:18:12,621 or at least contemplating the possibility of murdering her sister, 274 00:18:12,621 --> 00:18:13,981 for a period of time. 275 00:18:13,981 --> 00:18:16,581 It demonstrates the premeditation involved. 276 00:18:16,581 --> 00:18:18,941 This isn't a crime of passion, 277 00:18:18,941 --> 00:18:21,861 it's not an in-the-moment scenario. 278 00:18:21,861 --> 00:18:24,581 This is somebody who has orchestrated 279 00:18:24,581 --> 00:18:29,141 the downfall of another human being, her own sister, 280 00:18:29,141 --> 00:18:32,941 somebody that she's grown up with, lived with, loved. 281 00:18:32,941 --> 00:18:36,261 She has been living with her whilst planning her death. 282 00:18:38,941 --> 00:18:41,221 NEWSREADER: It's 11:00, I'm Simon Oxley. 283 00:18:41,221 --> 00:18:42,421 The headlines... 284 00:18:45,301 --> 00:18:48,981 As the police focus shifts onto the victim's sister, 285 00:18:49,741 --> 00:18:54,421 in Overstone Road, scene of crime officers make a crucial discovery, 286 00:18:57,661 --> 00:18:59,101 in Sabah's bedroom. 287 00:18:59,101 --> 00:19:02,141 They found the bag, which had some blood-stained clothing, 288 00:19:02,981 --> 00:19:05,501 and they found a murder weapon with blood on it. 289 00:19:06,661 --> 00:19:09,541 The evidence was sitting in that bag. 290 00:19:09,541 --> 00:19:12,141 There was the knife, there were bloodied clothes. 291 00:19:15,901 --> 00:19:20,661 The murder weapon and clothes are swiftly sent for forensic tests. 292 00:19:20,661 --> 00:19:23,221 The results - damning. 293 00:19:23,221 --> 00:19:26,741 The police also found a black hoodie inside the bag 294 00:19:26,741 --> 00:19:29,741 in Sabah Khan's bedroom, and they analysed it 295 00:19:29,741 --> 00:19:34,261 and found there were flecks of glass on the hoodie, 296 00:19:34,261 --> 00:19:39,621 which showed that she had been near the door when it had been broken, 297 00:19:39,621 --> 00:19:44,421 supposedly by the burglars, but actually by Sabah Khan herself. 298 00:19:50,461 --> 00:19:52,581 REPORTER: Sabah Khan from Newark Road in Luton 299 00:19:52,581 --> 00:19:55,581 was arrested by Bedfordshire Police on Tuesday. 300 00:19:55,581 -->

traces of Saima's DNA. 303 00:20:03,781 --> 00:20:06,581 We're now thinking, "We've cracked the case now. We've solved it." 304 00:20:12,071 --> 00:20:13,831 REPORTER: Sabah Khan from Luton was arrested 305 00:20:13,831 --> 00:20:15,231 by Bedfordshire Police on Tuesday. 306 00:20:15,231 --> 00:20:18,031 The 26-year-old is accused of murdering her sister. 307 00:20:22,391 --> 00:20:24,591 NARRATOR: Sabah Khan has been arrested 308 00:20:24,591 --> 00:20:27,071 for the murder of her sister, Saima. 309 00:20:28,271 --> 00:20:30,991 The killer had been in front of police all along. 310 00:20:32,991 --> 00:20:35,231 But what turns a loving daughter, 311 00:20:35,231 --> 00:20:38,831 a devoted sister, into a cold-blooded killer? 312 00:20:40,031 --> 00:20:44,471 And how had Sabah Khan got away with her crime for eight days? 313 00:20:57,231 --> 00:21:01,631 After the murder, Sabah may have felt some relief 314 00:21:01,631 --> 00:21:04,831 that she'd actually done what she had planned to do. 315 00:21:04,831 --> 00:21:09,791 And there may have been a period where she was thinking a little bit 316 00:21:09,791 --> 00:21:14,751 more clearly but focused on diverting the police investigation. 317 00:21:17,111 --> 00:21:20,671 Journalist Emily Pennink was hot on the story. 318 00:21:21,311 --> 00:21:23,311 She was staging a burglary. 319 00:21:23,311 --> 00:21:26,631 Afterwards, she hid the blood-stained knife 320 00:21:26,631 --> 00:21:29,271 and the clothes that she had been wearing, 321 00:21:29,271 --> 00:21:31,071 including the black hoodie, 322 00:21:31,071 --> 00:21:33,711 and she smashed the back door 323 00:21:33,711 --> 00:21:37,991 and she'd upturned a box of jewellery, as well. 324 00:21:37,991 --> 00:21:41,431 So she'd really considered it very carefully, 325 00:21:41,431 --> 00:21:44,351 and she'd carried it out 326 00:21:44,351 --> 00:21:48,951 with cold and calculating precision 327 00:21:49,911 --> 00:21:51,751 to make it look like a burglary. 328 00:21:58,711 --> 00:22:00,271 She's created a scene, 329 00:22:00,271 --> 00:22:04,311 now Sabah needs to get rid of the evidence, and takes a shower. 330 00:22:05,551 --> 00:22:07,831 I cannot think that you could stab someone over 60 times 331 00:22:07,831 --> 00:22:09,791 and not get covered in blood. 332 00:22:12,311 --> 00:22:15,071 Having set the scene of a burglary gone wrong, 333 00:22:15,071 --> 00:22:18,351 Sabah's plan is in place, but for it to work, 334 00:22:18,351 --> 00:22:22,471 she needs to notify people of her supposed discovery. 335 00:22:22,471 --> 00:22:25,991 But it's not the police she calls.
