00:04:04,767 One sock was off, the other sock appeared to be coming off. 84 00:04:04,867 --> 00:04:06,867 So she might have been dragged 85 00:04:06,867 --> 00:04:09,800 down the staircase by the suspect. 86 00:04:09,867 --> 00:04:12,600 A pair of black underwear were lying 87 00:04:12,667 --> 00:04:14,967 on the floor next to her head. 88 00:04:14,967 --> 00:04:17,367 HENDERSON: We think she

00:04:22,867 --> 00:04:28,367 been wiped with household cleaners to possibly cover up 92 00:04:28,367 --> 00:04:30,000 sexual assault. 93 00:04:30,000 --> 00:04:30,100 sexual assault. 94 00:04:30,166

somebody is very angry. 100 00:04:46,867 --> 00:04:50,667 It seems to be very personal in nature. 101 00:04:50,667 --> 00:04:53,400 NARRATOR: Who could have committed such a brutal attack? 102 00:04:54,867 --> 00:04:57,100 Detectives search the house for clues. 103 00:04:57,166 --> 00:04:58,967 MANOCHIO: What we noticed immediately 104 00:04:58,967 --> 00:05:00,000 that there was no forced

personal items were ransacked 108 00:05:05,567 --> 00:05:07,400 like you would typically see in a robbery, 109 00:05:07,467 --> 00:05:08,900 MANOCHIO: Her pocketbook was there, 110 00:05:09,000 --> 00:05:11,567 her house keys, her car was in the driveway. 111 00:05:12,800 --> 00:05:16,300 GARDNER: It suggests that Diane knew who the suspect was 112 00:05:16,367 --> 00:05:18,667 and that she let him into the house. 113 00:05:21,367 --> 00:05:22,700 NARRATOR: Detectives want to know 114 00:05:22,767 --> 00:05:25,667 who came knocking at Diane's door. 115 00:05:26,767 --> 00:05:28,567 A first look at the crime scene 116 00:05:28,667 --> 00:05:30,000 suggests the attack began in the foyer. 117 00:05:30,000 --> 00:05:30,667 suggests the attack began in the foyer. 118 00:05:31,967 -->

00:05:41,066 --> 00:05:43,266 he dragged her body down to the basement. 122 00:05:45,567 --> 00:05:48,100 NARRATOR: As investigators move through the rooms, 123 00:05:48,166 --> 00:05:50,066 there's further evidence the perpetrator 124 00:05:50,066 --> 00:05:51,900 was familiar with Diane's home. 125 00:05:53,467 --> 00:05:54,667 MANOCHIO: As I entered the bathroom, 126 00:05:54,700 -->

would have never made that. 137 00:06:20,367 --> 00:06:23,767 So we knew whoever made that meal wasn't Diane. 138 00:06:25,300 --> 00:06:27,266 STOCKDALE: The killer chose to remain at the crime scene, 139 00:06:27,367 --> 00:06:30,000 taking their time, even preparing a meal. 140 00:06:30,000 --> 00:06:30,166 taking their time, even preparing a meal. 141 00:06:30,266 --> 00:06:32,500 They

killer. 144 00:06:38,567 --> 00:06:39,767 NARRATOR: There is mounting evidence 145 00:06:39,767 --> 00:06:42,100 Diane knew the perpetrator. 146 00:06:42,166 --> 00:06:44,500 The forensics team makes more discoveries 147 00:06:44,567 --> 00:06:46,367 that may help reveal his identity. 148 00:06:48,567 --> 00:06:51,900 MANOCHIO: The living room area had a bay window with curtains, 149 00:06:52,000

our suspect's DNA blood on the curtain. 155 00:07:05,967 --> 00:07:07,667 It was an important piece of 156 00:07:07,767 --> 00:07:11,166 evidence that we wanted to test immediately. 157 00:07:11,166

o'clock, Diane's parents find her at 203 00:09:02,567 --> 00:09:06,166 the bottom of the stairs and call 911. 204 00:09:06,266 --> 00:09:08,400 NARRATOR: Detectives know that Diane was killed 205 00:09:08,467 --> 00:09:10,400 sometime between her parents discovering 206 00:09:10,467 --> 00:09:14,567 her body and her phone call to her mother 24 hours earlier. 207 00:09:14,667 --> 00:09:17,400 Although the medical examiner is unable to establish 208 00:09:17,467 --> 00:09:18,967 the cause of death, 209 00:09:18,967 --> 00:09:21,667 he is able to narrow down when it occurred. 210 00:09:23,400 --> 00:09:25,667 He takes the temperature of the room. 211 00:09:25,767 --> 00:09:28,467 He takes the temperature of the victim's body, 212 00:09:28,567 --> 00:09:30,000 and he calculates time of death 213 00:09:30,000 --> 00:09:31,000 and he calculates time of death 214 00:09:31,066 --> 00:09:34,200 between 10 p.m. and 1 a.m. the night before 215 00:09:37,667 --> 00:09:38,667 NARRATOR: Back in the kitchen, 216 00:09:38,700 --> 00:09:40,667 detectives note an odd detail that further 217 00:09:40,667 --> 00:09:44,467 confirms their suspicion that the killer knew Diane. 218 00:09:44,567 --> 00:09:46,367 HENDERSON: The garbage can from the kitchen is 219 00:09:46,467 --> 00:09:49,467 nowhere to be found, but the garbage can from 220 00:09:49,467 --> 00:09:53,700 the outside of the house is at the sidewalk, empty, 221 00:09:53,767 --> 00:09:55,900 and we discovered that it was garbage day. 222 00:09:56,000 --> 00:09:59,000 So we thought that was very interesting. 223 00:09:59,066 --> 00:10:00,000 GARDNER: The fact that the garbage was put out that night 224 00:10:00,000 --> 00:10:02,867 GARDNER: The fact that the garbage was put out that night 225 00:10:02,967 --> 00:10:07,066 indicates to me that the suspect knew 226 00:10:07,066 --> 00:10:10,900 the area, he knew when garbage pickup would be. 227 00:10:11,000 --> 00:10:14,166 NARRATOR: The suspect may not only be someone Diane knows, 228 00:10:14,266 --> 00:10:16,400 he may even live nearby. 229 00:10:17,867 --> 00:10:19,700 We were asking the neighbors 230 00:10:19,767 --> 00:10:22,000 if they had heard anything suspicious. 231 00:10:22,100 --> 00:10:24,467 One neighbor that was asked if she had seen anything and said, 232 00:10:24,567 --> 00:10:27,100 "Well, I didn't see anything unusual. 233 00:10:27,166 --> 00:10:28,867 "All I saw in front of the house that 234 00:10:28,867 --> 00:10:30,000 "day were two young African-American kids 235 00:10:30,000 --> 00:10:31,767 "day were two young African-American kids 236 00:10:31,767 --> 00:10:33,667 playing football," 237 00:10:33,667 --> 00:10:35,367 but she didn't think anything of it. 238 00:10:35,367 --> 00:10:38,200 There was a lot of kids in the neighborhood who would 239 00:10:38,266 --> 00:10:42,100 actually help Diane in her home, either throwing out the garbage, 240 00:10:42,166 --> 00:10:44,867 shoveling her driveway in the wintertime. 241 00:10:44,967 --> 00:10:47,467 Directly across the street from Diane's house, 242 00:10:47,567 --> 00:10:49,266 the owner is Ms. Yearwood. 243 00:10:49,367 --> 00:10:51,367 MANOCHIO: We asked her who she lives with, 244 00:10:51,467 --> 00:10:54,567 and the only individuals that she identified living 245 00:10:54,567 --> 00:10:56,166 in her home was herself, 246 00:10:56,166 --> 00:10:58,400 her daughter, and her grandson. 247 00:10:58,467 --> 00:11:00,000 Nobody had seen anything, nobody heard anything. 248 00:11:00,000 --> 00:11:01,066 Nobody had seen anything, nobody heard anything. 249 00:11:01,066 --> 00:11:03,066 They didn't pay any attention to anything. 250 00:11:03,066 --> 00:11:04,800 So that led us to a dead end. 251 00:11:06,000 --> 00:11:07,667 NARRATOR: None of Diane's other neighbors saw 252 00:11:07,667 --> 00:11:09,900 or heard anything out of the ordinary either. 253 00:11:11,767 --> 00:11:13,800 Then detectives receive news 254 00:11:13,867 --> 00:11:16,266 that narrows their suspect search. 255 00:11:16,367 --> 00:11:18,500 MANOCHIO: It was a male profile that was 256 00:11:18,567 --> 00:11:21,667 on the curtain of the bay window. 257 00:11:21,767 --> 00:11:23,767 So right then and there, we knew we had 258 00:11:23,767 --> 00:11:26,367 what we believe would be the killer. 259 00:11:26,467 --> 00:11:28,000 NARRATOR: Now detectives need to find 260 00:11:28,066 --> 00:11:29,467 the person who matches it. 261 00:11:30,667 --> 00:11:33,767 So they focus on the men in Diane's life. 262 00:11:33,767 --> 00:11:36,500 She didn't have a primary boyfriend, but she did 263 00:11:36,567 --> 00:11:38,000 go on the dating scene a lot. 264 00:11:38,100 --> 00:11:39,967 She liked to go out, she liked to party, 265 00:11:39,967 --> 00:11:41,600 she liked to have fun. 266 00:11:41,667 --> 00:11:43,400 MANOCHIO: She had several hundred contacts 267 00:11:43,467 --> 00:11:44,867 in her cellphone. 268 00:11:44,867 --> 00:11:48,300 While searching through Diane's phone contacts, 269 00:11:48,367 --> 00:11:51,367 we locate the name of Bob Bass. 270 00:11:52,767 --> 00:11:56,867 He had a 20-year relationship with Diane 271 00:11:56,967 --> 00:11:59,800 He actually asked her father for her hand in marriage. 272 00:11:59,867 --> 00:12:00,000 I guess he didn't give it, because they eventually 273 00:12:00,000 --> 00:12:02,000 I guess he didn't give it, because they eventually 274 00:12:02,066 --> 00:12:03,200 broke up. 275 00:12:03,266 --> 00:12:06,266 Diane and Bob Bass had a very tumultuous relationship. 276 00:12:06,266 --> 00:12:08,400 They tended to argue all the time, 277 00:12:08,467 --> 00:12:11,100 and he was a very angry individual. 278 00:12:11,166 --> 00:12:13,500 You're looking for somebody who does have a temper, 279 00:12:13,567 --> 00:12:18,500 who is angry, and who does have a reason to murder Diane. 280 00:12:20,000 --> 00:12:22,900 Right then and there, we knew that this could be our guy. 281 00:12:29,467 --> 00:12:31,967 NARRATOR: When investigators discover Diane Zaleski 282 00:12:31,967 --> 00:12:33,867 murdered in her New Jersey home, 283 00:12:33,867 --> 00:12:37,700 their suspicions turned to her ex-fiance, Bob Bass. 284 00:12:38,700 --> 00:12:40,400 Their relationship had been tumultuous 285 00:12:40,467 --> 00:12:42,467 before Diane ended the engagement. 286 00:12:43,500 --> 00:12:45,967 MANOCHIO: We ran Bob Bass's phone number 287 00:12:45,967 --> 00:12:47,667 through Subscriber Information, 288 00:12:47,667 --> 00:12:50,166 and we discovered it was a completely different name. 289 00:12:50,166 --> 00:12:53,266 So we find out that his name is Roberto Bennett, 290 00:12:53,367 --> 00:12:56,467 and it appears he's got a criminal record. 291 00:12:56,467 --> 00:12:57,767 HENDERSON: He was divorced, 292 00:12:57,867 --> 00:12:57,980 and he'd been arrested for domestic violence. 293 00:12:57,980 --> 00:13:00,500 and he'd been arrested for domestic violence. 294 00:13:01,567 --> 00:13:04,400 We speak to his wife, his former wife. 295 00:13:04,467 --> 00:13:07,000 Turns out, he actually sat on her chest 296 00:13:07,066 --> 00:13:11,867 and pummeled her in the face with closed fists so bad that 297 00:13:11,867 --> 00:13:13,767 he broke her eye orbital. 298 00:13:13,867 --> 00:13:17,300 Putting two and two together, Diane is beaten badly. 299 00:13:17,367 --> 00:13:19,166 We think this is our guy. 300 00:13:25,967 --> 00:13:27,980 The number-one predictor of future violence is 301 00:13:27,980 --> 00:13:29,100 The number-one predictor of future violence is 302 00:13:29,166 --> 00:13:31,100 past violence, so when it's learned that 303 00:13:31,166 --> 00:13:34,600 Bob's been domestically violent in relationships, 304 00:13:34,667 --> 00:13:36,100 it increases the odds that he 305 00:13:36,166 --> 00:13:39,467 could escalate and commit a murder. 306 00:13:39,467 --> 00:13:42,367 NARRATOR: Investigators have a prime suspect. 307 00:13:42,367 --> 00:13:44,467 Now they have to find him. 308 00:13:44,467 --> 00:13:46,767 MANOCHIO: He was not at his job, he was not at his home. 309 00:13:46,867 --> 00:13:48,600 We tried calling him, he wouldn't come in. 310 00:13:48,667 --> 00:13:50,567 He wasn't being cooperative. 311 00:13:50,667 --> 00:13:53,100 We dug a little deeper into his driver's license, 312 00:13:53,166 --> 00:13:56,400 and we realized that he had several DWIs 313 00:13:56,467 --> 00:13:57,567 in the state of New Jersey, 314 00:13:57,667 --> 00:13:57,980 which required him to do weekend jail time 315 00:13:57,980 --> 00:14:00,266 which required him to do weekend jail time 316 00:14:00,266 --> 00:14:01,900 in the Union County jail. 317 00:14:02,000 --> 00:14:04,867 So me and detective Rob Henderson went out there on 318 00:14:04,967 --> 00:14:08,166 a Friday, and that's when we got to talk to Roberto Bennett. 319 00:14:09,166 --> 00:14:11,900 We bring Roberto Bennett into the interview room, 320 00:14:12,000 --> 00:14:14,867 and we stated that we were investigating a death in 321 00:14:14,867 --> 00:14:16,467 the township of Union, 322 00:14:16,467 --> 00:14:17,900 and the victim's name is Diane Zaleski, 323 00:14:18,700 --> 00:14:20,567 and he denied knowing her. 324 00:14:20,567 --> 00:14:21,800 I don't know who she is. 325 00:14:21,867 --> 00:14:24,767 I don't know why my phone would be in her phone. 326 00:14:24,867 --> 00:14:27,980 I said, "Are you sure that you don't know Diane Zaleski?" 327 00:14:27,980 --> 00:14:28,300 I said, "Are you sure that you don't know Diane Zaleski?" 328 00:14:28,367 --> 00:14:29,767 He goes, "I'm positive." 329 00:14:29,867 --> 00:14:32,800 So we had a color photograph of Diane, and we put it in front 330 00:14:32,867 --> 00:14:35,000 of him, and he goes, "I still don't know that girl," 331 00:14:35,066 --> 00:14:38,000 which we felt was kind of ballsy, because not only did 332 00:14:38,100 --> 00:14:40,867 the family tell us that he wanted to marry her, 333 00:14:40,967 --> 00:14:44,700 that they dated for several years in a crazy relationship, 334 00:14:44,767 --> 00:14:47,767 he also rented an apartment to her prior to her 335 00:14:47,867 --> 00:14:50,900 moving into her permanent residence in Union Township. 336 00:14:52,100 --> 00:14:54,667 NARRATOR: Detectives know Roberto is lying, 337 00:14:54,767 --> 00:14:56,400 but to prove he's the killer, 338 00:14:56,467 --> 00:14:57,980 they need him to provide a DNA sample to compare with 339 00:14:57,980 --> 00:14:59,367 they need him to provide a DNA sample to compare with 340 00:14:59,467 --> 00:15:01,600 the blood sample taken from the crime scene. 341 00:15:02,867 --> 00:15:05,266 GARDNER: Mr. Bennett is also refusing 342 00:15:05,266 --> 00:15:07,867 to give us a DNA profile. 343 00:15:07,867 --> 00:15:11,867 He finally agrees to give us a sample after he's 344 00:15:11,867 --> 00:15:14,800 threatened to be held in custody longer than 345 00:15:14,867 --> 00:15:16,367 his weekends. 346 00:15:16,467 --> 00:15:19,266 MANOCHIO: We compare that DNA sample to 347 00:15:19,367 --> 00:15:22,266 the DNA sample collected at the crime scene, 348 00:15:22,266 --> 00:15:25,200 and unfortunately, it was not our guy, 349 00:15:25,266 --> 00:15:27,767 and that was like a punch in the stomach. 350 00:15:27,767 --> 00:15:27,980 ARNTFIELD: This is one of those cases whereby you have 351 00:15:27,980 --> 00:15:30,500 ARNTFIELD: This is one of those cases whereby you have 352 00:15:30,567 --> 00:15:33,800 a suspect on paper who ticks all the boxes, 353 00:15:33,867 --> 00:15:36,767 and yet ultimately, DNA science, 354 00:15:36,867 --> 00:15:40,767 the physical evidence, confirms that they're not the one. 355 00:15:42,000 --> 00:15:44,600 NARRATOR: Roberto Bennett is not Diane's killer. 356 00:15:45,600 --> 00:15:49,200 Detectives must continue to sift through her personal life. 357 00:15:49,266 --> 00:15:52,800 So at this point, we started contacting every male profile 358 00:15:52,867 --> 00:15:56,800 that we can come up with, in her phone and in her dating 359 00:15:56,867 --> 00:15:57,980 websites, and it was over 80 men. 360 00:15:57,980 --> 00:15:59,967 websites, and it was over 80 men. 361 00:15:59,967 --> 00:16:02,567 HENDERSON: Mike and I literally were there 362 00:16:02,567 --> 00:16:05,200 for hours and hours and hours every single day, 363 00:16:05,266 --> 00:16:07,767 contacting the people, setting up interviews. 364 00:16:07,867 --> 00:16:10,867 MANOCHIO: These individuals, they came in voluntarily. 365 00:16:10,867 --> 00:16:13,000 They wanted to know about Diane. 366 00:16:13,066 --> 00:16:14,567 They were humble about it. 367 00:16:14,667 --> 00:16:15,867 A lot of guys broke down 368 00:16:15,967 --> 00:16:18,166 in the office, crying about Diane's death. 369 00:16:18,166 --> 00:16:21,367 They volunteered to provide a buckle swab. 370 00:16:21,367 --> 00:16:26,266 All of those acquaintances were all ruled out as suspects. 371 00:16:26,367 --> 00:16:27,667 No DNA matched. 372 00:16:29,300 --> 00:16:32,467 NARRATOR: Investigators hit a wall -- to climb over it, 373 00:16:32,467 --> 00:16:33,300 they look at a different piece 374 00:16:33,367 --> 00:16:35,367 of evidence from the crime scene. 375 00:16:35,367 --> 00:16:37,500 MANOCHIO: We have Diane Zaleski's pocketbook 376 00:16:37,567 --> 00:16:39,467 in our evidence locker. 377 00:16:39,467 --> 00:16:44,467 We go through her pocketbook, and we identify 378 00:16:44,567 --> 00:16:48,166 a business card with the name of Marty Oppenheimer on it. 379 00:16:48,166 --> 00:16:51,800 So we contact this Marty Oppenheimer, who 380 00:16:51,867 --> 00:16:54,600 comes down to our office for an interview. 381 00:16:54,667 --> 00:16:57,467 He is very aggressive. 382 00:16:57,467 --> 00:16:57,980 His statement is very awkward. 383 00:16:57,980 --> 00:16:59,567 His statement is very awkward. 384 00:16:59,567 --> 00:17:03,000 He didn't appear to be as genuine 385 00:17:03,100 --> 00:17:06,700 and open as the other 80 individuals that 386 00:17:06,767 --> 00:17:08,066 we interviewed. 387 00:17:08,066 --> 00:17:10,600 He acknowledged that he knew Diane, 388 00:17:10,667 --> 00:17:13,000 but he stated that that's not the type of woman 389 00:17:13,100 --> 00:17:14,767 he would target. 390 00:17:14,867 --> 00:17:16,166

because it almost 394 00:17:25,467 --> 00:17:27,980 implies that he's going out and preying on potential women 395 00:17:27,980 --> 00:17:29,400 implies that he's going out and preying on potential women 396 00:17:29,467 --> 00:17:31,900 or victims, and so this is something that would 397 00:17:32,000 --> 00:17:35,066 cause investigators to wish to follow up. 398 00:17:35,066 --> 00:17:38,000

00:22:15,567 --> 00:22:18,567 There must have been a mix-up in the laundry 511 00:22:18,667 --> 00:22:22,166 with the underwear, and Diane probably had 512 00:22:22,266 --> 00:22:25,567 Debbie's

00:22:54,400 MANOCHIO: So right then and there, 524 00:22:54,467 --> 00:22:56,367 we cleared up the whole mystery 525 00:22:56,467 --> 00:22:59,341 of why Pete's male DNA was in his sister's underwear. 526 00:22:59,341 --> 00:23:00,967 of why Pete's male DNA was in his sister's underwear. 527 00:23:02,100 --> 00:23:05,800 Turns out it was just really a laundry accident. 528 00:23:05,867 --> 00:23:07,667 NARRATOR: Despite the expert's opinion, 529 00:23:07,667 --> 00:23:10,567 investigators still have their doubts. 530 00:23:10,567 --> 00:23:13,066 There's one surefire way to confirm whether 531 00:23:13,066 --> 00:23:15,900 Peter was responsible for his sister's murder. 532 00:23:16,000 --> 00:23:19,100 We requested that Pete's profile be compared to 533 00:23:19,166 --> 00:23:21,300 the other male blood profile that was collected at 534 00:23:21,367 --> 00:23:22,800 the scene. 535 00:23:22,867 --> 00:23:25,100 NARRATOR: While Peter's semen found inside the underwear 536 00:23:25,166 --> 00:23:26,600 could be explained away, 537 00:23:26,667 --> 00:23:29,341 a DNA match to the male blood found at the scene 538 00:23:29,341 --> 00:23:30,367 a DNA match to the male blood found at the scene 539 00:23:30,467 --> 00:23:33,500 would help prove that Diane's brother stabbed her to death. 540 00:23:38,300 --> 00:23:41,166 NARRATOR: Peter Zaleski's DNA was found inside 541 00:23:41,266 --> 00:23:44,500 women's underwear at the scene of his sister Diane's murder. 542 00:23:45,467 --> 00:23:48,867 Now investigators await results of whether his DNA is 543 00:23:48,867 --> 00:23:52,000 a match for the killer's blood discovered in Diane's house. 544 00:23:53,400 --> 00:23:55,667 There were two different profiles. 545 00:23:55,767 --> 00:23:58,266 So we knew the killer was still out there. 546 00:23:58,367 --> 00:24:00,567 NARRATOR: After nearly 12 months of investigation, 547 00:24:00,667 --> 00:24:04,000 detectives are no closer to solving Diane's homicide. 548 00:24:05,867 --> 00:24:06,214 They decide to turn to the FBI Behavioral Analysis Unit 549 00:24:06,214 --> 00:24:09,500 They decide to turn to the FBI Behavioral Analysis Unit 550 00:24:09,567 --> 00:24:11,467 in Quantico, Virginia, for help. 551 00:24:11,467 --> 00:24:13,367 In cases that are challenging, 552 00:24:13,367 --> 00:24:16,767 investigators may reach out to experts in human behavior, 553 00:24:16,767 --> 00:24:19,700 such as psychologists or psychiatrists, to help look at 554 00:24:19,767 --> 00:24:22,400 the behavioral patterns present. 555 00:24:22,467 --> 00:24:25,166 HENDERSON: You lay out all your evidence, 556 00:24:25,266 --> 00:24:27,767 people you've interviewed, everything you've done, 557 00:24:27,767 --> 00:24:29,567 and everybody brainstorms. 558 00:24:29,667 --> 00:24:30,867 NARRATOR: To build a profile 559 00:24:30,900 --> 00:24:34,767 of the likely killer, FBI agents focus on activity found 560 00:24:34,867 --> 00:24:36,100 on Diane's computer. 561 00:24:37,567 --> 00:24:39,900 At 1 a.m. on November 18th, 562 00:24:40,000 --> 00:24:42,700 11 hours before her body is found, 563 00:24:42,767 --> 00:24:44,600 someone was surfing the web. 564 00:24:44,667 --> 00:24:48,000 He had tried to purchase an Apple iPhone, 565 00:24:48,100 --> 00:24:52,166 an iMac -- their thinking was, the killer was probably young, 566 00:24:52,166 --> 00:24:53,600 into high-tech stuff. 567 00:24:53,667 --> 00:24:55,900 NARRATOR: His attempted purchase also suggests to 568 00:24:56,000 --> 00:24:58,567 agents that the killer may be local. 569 00:24:58,567 --> 00:25:00,667 He might be a neighbor who was able to watch 570 00:25:00,767 --> 00:25:03,000 the house to see if there were deliveries being made. 571 00:25:04,166 --> 00:25:06,214 The individual also accessed some porn sites. 572 00:25:06,214 --> 00:25:08,100 The individual also accessed some porn sites. 573 00:25:08,166 --> 00:25:09,967 HENDERSON: They also thought he might have been black, 574 00:25:09,967 --> 00:25:12,567 because of the Lexington Steele porn. 575 00:25:12,667 --> 00:25:16,800 Lexington Steele was a black man from Union Township. 576 00:25:16,867 --> 00:25:19,166 NARRATOR: But the FBI analysis can't account 577 00:25:19,166 --> 00:25:21,000 for all of the killer's behavior. 578 00:25:21,066 --> 00:25:24,200 A normal person who's thinking rationally is not going to go 579 00:25:24,266 --> 00:25:27,000 on to a computer and watch 580 00:25:27,066 --> 00:25:29,467 pornography after he's killed somebody. 581 00:25:29,567 --> 00:25:30,667 A normal person, 582 00:25:30,700 --> 00:25:32,300 after doing all of these things, isn't going to take 583 00:25:32,367 --> 00:25:35,700 a credit card and try to buy items off a computer. 584 00:25:35,767 --> 00:25:36,214 The thinking process wasn't 585 00:25:36,214 --> 00:25:37,266 The thinking process wasn't 586 00:25:37,367 --> 00:25:39,367 the same as somebody that is cognizant. 587 00:25:40,300 --> 00:25:43,400 MANOCHIO: What they concluded was the individual responsible 588 00:25:43,467 --> 00:25:46,567 for this was a drifter, a loner, a drug addict, 589 00:25:46,567 --> 00:25:48,266 someone with no friends, 590 00:25:48,367 --> 00:25:51,467 no career, someone who wasn't doing well in life. 591 00:25:52,667 --> 00:25:54,166 Probably not a serial killer, 592 00:25:54,266 --> 00:25:57,266 probably didn't mean to kill Diane, either. 593 00:25:57,266 --> 00:25:59,467 This was a crime of opportunity, 594 00:25:59,567 --> 00:26:01,967 and a crime of chance. 595 00:26:01,967 --> 00:26:04,500 NARRATOR: Now with the killer's profile in hand, 596 00:26:04,567 --> 00:26:06,214 detectives can narrow leads from the general public. 597 00:26:06,214 --> 00:26:07,367 detectives can narrow leads from the general public. 598 00:26:07,467 --> 00:26:10,667 So on the one-year anniversary of Diane's death, 599 00:26:10,767 --> 00:26:13,500 investigators reach out to the media to help them get 600 00:26:13,567 --> 00:26:14,867 the word out. 601 00:26:14,867 --> 00:26:18,100 ARNTFIELD: As time marches on, and cases remain cold, 602 00:26:18,166 --> 00:26:19,467 it's important for investigators to 603 00:26:19,567 --> 00:26:21,600 consider releasing some additional information 604 00:26:21,667 --> 00:26:24,266 that can provide renewed context, 605 00:26:24,367 --> 00:26:26,567 keep the case in the public eye. 606 00:26:26,567 --> 00:26:28,700 You can't expect the public to provide 607 00:26:28,767 --> 00:26:31,000 information if it's only a one-way street. 608 00:26:31,066 --> 00:26:34,500 MANOCHIO: This time, we put a little more details in to 609 00:26:34,567 --> 00:26:36,214 alert the readers and the media of what we have. 610 00:26:36,214 --> 00:26:37,500 alert the readers and the media of what we have. 611 00:26:37,567 --> 00:26:40,600 We told the public that a meal was prepared, 612 00:26:40,667 --> 00:26:43,266 that he had eaten something while he was there, 613 00:26:43,367 --> 00:26:46,767 and that we had DNA, which we hadn't said before. 614 00:26:46,767 --> 00:26:50,800 Maybe somebody that didn't see something a year ago, 615 00:26:50,867 --> 00:26:54,900 maybe they remember all of a sudden -- in doing that, 616 00:26:55,000 --> 00:26:56,200 I also put out my cellphone number, 617 00:26:56,266 --> 00:26:59,266 so if anybody had anything, they could call me. 618 00:27:01,100 --> 00:27:03,800 NARRATOR: But the media blitz produces no new leads. 619 00:27:05,100 --> 00:27:06,214 HENDERSON: I had an entire desk full of the Diane investigation. 620 00:27:06,214 --> 00:27:09,300 HENDERSON: I had an entire desk full of the Diane investigation. 621 00:27:09,367 --> 00:27:10,667 Five-inch binders, 622 00:27:10,667 --> 00:27:14,900 probably 10 of them, crammed with interviews, 623 00:27:15,000 --> 00:27:17,000 background investigations for all the people, 624 00:27:17,066 --> 00:27:19,400 all the guys I'd taken buckle samples from, 625 00:27:19,467 --> 00:27:22,467 and my boss said, "We're getting a new detective Monday. 626 00:27:22,467 --> 00:27:24,367 You're gonna have to clean the desk." 627 00:27:24,467 --> 00:27:26,867 It was the worst day of my life, that I had to put Diane on 628 00:27:26,967 --> 00:27:29,600 the shelf, because when you put something on the shelf, 629 00:27:29,667 --> 00:27:33,100 it turns into a cold case, and we all know how cold cases go. 630 00:27:35,266 --> 00:27:36,214 NARRATOR: Diane Zaleski's case sits on the shelf 631 00:27:36,214 -->

he has a body on him in New Jersey. 642 00:28:09,667 --> 00:28:11,700 NARRATOR: Having a body on him is street slang 643 00:28:11,767 --> 00:28:13,767 boasting about a murder. 644 00:28:13,867 -->

00:28:26,767 --> 00:28:28,567 what he did inside the house. 651 00:28:28,667 --> 00:28:31,767 HENDERSON: She's telling me that he was sitting around 652 00:28:31,767 --> 00:28:33,867 in his underwear

00:35:39,567 --> 00:35:40,935 The way Arnell described it was, 815 00:35:40,935 --> 00:35:42,667 The way Arnell described it was, 816 00:35:42,667 --> 00:35:45,800 he would provide drugs to Diane, and they would have 817 00:35:45,867 --> 00:35:48,367 a sexual relationship. 818 00:35:48,467 --> 00:35:50,367 MANOCHIO: He said he was high 819 00:35:50,467 --> 00:35:54,467 at the time, and he said he couldn't get sexually aroused, 820 00:35:54,567 --> 00:35:56,266 and apparently Diane laughed at him, 821 00:35:56,367 --> 00:35:59,166 and he didn't take that too well. 822 00:35:59,266 --> 00:36:02,266 So he stated he grabbed the only thing he could find at 823 00:36:02,367 --> 00:36:03,967 the time, which was a pair of scissors, 824 00:36:03,967 --> 00:36:05,567 and he started stabbing her, 825 00:36:07,200 --> 00:36:09,467 and he doesn't remember anything after that. 826 00:36:09,567 --> 00:36:10,900 That's what he said. 827 00:36:11,000 --> 00:36:12,867 And we didn't believe that for one second. 828 00:36:12,867 --> 00:36:16,567 There were no drugs in Diane's system of any kind. 829 00:36:16,667 --> 00:36:20,100 I think maybe he propositioned her for sex that night 830 00:36:20,166 --> 00:36:22,000 and she probably 831 00:36:22,066 --> 00:36:23,867 did laugh at him and turned him down, 832 00:36:23,967 --> 00:36:26,300 and that's what set him off. 833 00:36:28,500 --> 00:36:30,667 But I don't think they were having a relationship, 834 00:36:30,667 --> 00:36:31,967 by any means. 835 00:36:33,367 --> 00:36:37,800 STOCKDALE: I wonder if this is a fantasy seduction gone wrong. 836 00:36:37,867 --> 00:36:40,935 The fantasy may have been that Arnell goes to Diane's house 837 00:36:40,935 --> 00:36:42,066 The fantasy may have been that Arnell goes to Diane's house 838 00:36:42,066 --> 00:36:44,000 and makes a sexual or romantic 839 00:36:44,066 --> 00:36:47,266 overture towards her, and he doesn't get the response that 840 00:36:47,367 --> 00:36:49,600 he expects to get in his fantasy. 841 00:36:50,900 --> 00:36:52,767 When he's met with that rejection, 842 00:36:52,767 --> 00:36:56,567 it escalates into panic, and he feels like a failure, 843 00:36:56,567 --> 00:36:59,767 and so this results in aggression and the homicide. 844 00:37:02,500 --> 00:37:06,567 But still, he seeks to live out other elements of the fantasy, 845 00:37:06,567 --> 00:37:09,000 like having dinner, watching pornography. 846 00:37:09,066 --> 00:37:10,935 And I think that's why you see strange things 847 00:37:10,935 --> 00:37:11,166 And I think that's why you see strange things 848 00:37:11,166 --> 00:37:13,867 that aren't necessary for the commission of the crime. 849 00:37:15,567 --> 00:37:18,166 NARRATOR: Investigators are finally able to piece together 850 00:37:18,266 --> 00:37:21,100 the events that led to Diane Zaleski's murder. 851 00:37:22,166 --> 00:37:26,900 On November 17, 2010, at approximately 12 noon, 852 00:37:27,000 --> 00:37:29,867 neighbors identify Arnell Yearwood with his nephew 853 00:37:29,867 --> 00:37:30,900 playing football in front of 854 00:37:31,000 --> 00:37:34,266 Diane Zaleski's house -- because he's so small, 855 00:37:34,266 --> 00:37:36,567 they mistake him for one of the kids in the neighborhood. 856 00:37:36,567 --> 00:37:38,166 GARDNER: At approximately 1 p.m., 857 00:37:38,266 --> 00:37:40,935 Diane
