00:06:42,250 A broken jaw and collarbone 136 00:06:42,283 --> 00:06:46,830 indicated a crime of extraordinary violence. 137 00:06:46,116 --> 00:06:49,160 Annie was still wearing surgical gloves, 138 00:06:49,500 --> 00:06:51,383 indicating she had been working when attacked 139 00:06:52,160 --> 00:06:55,500 and was likely caught unaware. 140 00:06:55,830 --> 00:06:57,000 No murder weapon was recovered. 141 00:06:57,330 --> 00:07:00,333 It appeared her killer had used his bare hands, 142 00:07:00,366 --> 00:07:04,100 a possible indication of a spontaneous attack. 143 00:07:04,133 -->

day. 148 00:07:22,830 --> 00:07:25,350 What could possibly be worse than having her body 149 00:07:25,383 --> 00:07:28,300 found on the day she was to be married? 150 00:07:30,250 --> 00:07:32,333

immense. 153 00:07:39,133 --> 00:07:42,116 The FBI was involved, the New Haven Police was involved, 154 00:07:42,150 --> 00:07:43,283 the State Police was involved, 155 00:07:43,316 --> 00:07:46,383

sent to forensic analysts. 161 00:07:58,500 --> 00:08:02,300 One of those items didn't seem to fit with the other evidence. 162 00:08:02,333 --> 00:08:08,100 Found underneath Annie Le in that wall was a green pen. 163 00:08:08,133 --> 00:08:12,366 And that was very important to this investigation. 164 00:08:13,000 --> 00:08:18,100 Narrator: DNA tests were done on Annie's clothing and the green pen, 165 00:08:18,133 --> 00:08:22,266 as well as in the area where Annie's body was located. 166 00:08:22,300 --> 00:08:27,160 In a startling development, DNA from two different men 167 00:08:27,500 --> 00:08:29,300 was recovered from the area behind the wall. 168 00:08:29,333 --> 00:08:33,160 Both DNA samples were entered into CODIS, 169 00:08:33,500 --> 00:08:35,233 the national DNA database. 170 00:08:35,266 --> 00:08:37,166 In a crime this brutal, 171 00:08:37,200 --> 00:08:40,283 it was likely Annie's killer had been violent before 172 00:08:40,316 --> 00:08:43,316 and that his DNA would be in the system. 173 00:08:43,350 --> 00:08:47,316 Sure enough, analysts got a hit. 174 00:08:47,350 --> 00:08:49,350 A DNA profile came back, 175 00:08:49,383 --> 00:08:52,160 and it came back to a convicted felon. 176 00:08:52,500 --> 00:08:54,216 Narrator: His name was Kieran Robinson, 177 00:08:54,250 --> 00:08:58,200 and he was convicted in 2001 on drug charges. 178 00:08:58,233 --> 00:09:02,500 Now, investigators were sure they had a positive lead 179 00:09:02,830 --> 00:09:03,283 on a suspect, 180 00:09:03,316 --> 00:09:06,250 until the background check on Robinson came in. 181 00:09:06,283 --> 00:09:10,830 It turned out that the person who was the convicted felon 182 00:09:10,116 --> 00:09:13,250 had worked building the building, 183 00:09:13,283 --> 00:09:16,383 and then he was killed, shot in a bar 184 00:09:17,160 --> 00:09:20,000 sometime before Annie Le had gone missing. 185 00:09:20,330 --> 00:09:21,116 Narrator: A dead end. 186 00:09:21,150 --> 00:09:24,116 And even worse, the other DNA profile 187 00:09:24,150 --> 00:09:28,183 turned up no matches in the CODIS database. 188 00:09:28,216 --> 00:09:31,383 As the investigators used video surveillance to check 189 00:09:32,160 --> 00:09:35,266 every person who went in and out of the Amistad building, 190 00:09:35,300 --> 00:09:39,500 they turned to yet another aspect of Yale security 191 00:09:39,830 --> 00:09:41,660 that might reveal Annie's killer -- 192 00:09:41,100 --> 00:09:43,150 employee key cards. 193 00:09:43,183 --> 00:09:46,133 Those cards kept track of everyone's movements 194 00:09:46,166 --> 00:09:48,366 in the building at all times. 195 00:09:49,000 --> 00:09:53,500 The keycard system is something that is done 196 00:09:53,830 --> 00:09:56,000 to secure the research that's being done in rooms, 197 00:09:56,330 --> 00:09:58,266 who has access to it, and who goes in. 198 00:09:58,300 --> 00:10:01,200 Narrator: That information can be used to track people's 199 00:10:01,233 --> 00:10:04,216 activity over weeks, even months, 200 00:10:04,250 --> 00:10:06,133 and the investigation showed 201 00:10:06,166 --> 00:10:10,830 that one person's activity underwent a big change 202 00:10:10,116 --> 00:10:13,200 right about the time Annie Le went missing. 203 00:10:13,233 --> 00:10:16,350 When we were looking at who may have gained access, 204 00:10:16,383 --> 00:10:21,216 we saw one person kept going into Annie's research room, 205 00:10:21,250 --> 00:10:23,266 utilizing his keycard. 206 00:10:23,300 --> 00:10:27,333 Altimari: He was the last person that swiped into the lab 207 00:10:27,366 --> 00:10:30,500 that Annie had been seen in. 208 00:10:37,300 --> 00:10:39,160 [ Fire alarm sounding ] 209 00:10:39,500 --> 00:10:40,216 Narrator: On the day Annie Le went missing, 210 00:10:40,250 --> 00:10:43,250 shortly after she was last seen alive, 211 00:10:43,283 --> 00:10:46,383 a fire alarm went off in 10 Amistad. 212 00:10:47,160 --> 00:10:49,160 It turned out to be a false alarm, 213 00:10:49,500 --> 00:10:52,160 but everyone was forced to leave the building. 214 00:10:52,500 --> 00:10:54,150 Strollo: And all that video surveillance was viewed 215 00:10:54,183 --> 00:10:56,150 by the police time and time again, 216 00:10:56,183 --> 00:10:58,366 and Annie Le never left the building 217 00:10:59,000 --> 00:11:01,660 during the fire alarm at 12:55. 218 00:11:01,100 --> 00:11:05,216 Narrator: So, if Annie didn't evacuate 10 Amistad, 219 00:11:05,250 --> 00:11:10,330 she was probably dead before the fire alarm went off. 220 00:11:10,660 --> 00:11:13,660 But who had killed her and why? 221 00:11:13,100 --> 00:11:15,366 Investigators used employee key cards 222 00:11:16,000 --> 00:11:18,216 to retrace Annie's final steps. 223 00:11:18,250 --> 00:11:21,116 Chayes: You needed a keycard to get into certain rooms, 224 00:11:21,150 --> 00:11:25,250 including the one where Annie would do her experiments. 225 00:11:28,383 --> 00:11:31,383 Narrator: Keycard records showed that room, 226 00:11:32,160 --> 00:11:34,116 a lab known as G13, 227 00:11:34,150 --> 00:11:37,300 was Annie's last-known location, 228 00:11:37,333 --> 00:11:42,166 and some potentially interesting things were turning up there. 229 00:11:42,200 --> 00:11:46,500 Another student tipped off a Yale police officer 230 00:11:46,830 --> 00:11:47,383 that she had seen what she thought was blood 231 00:11:48,160 --> 00:11:50,216 on a box of wipes on a cart, 232 00:11:50,250 --> 00:11:53,200 and it turned out that that was indeed blood. 233 00:11:53,233 --> 00:11:54,366 There would be no reason for blood 234 00:11:55,000 --> 00:11:56,216 to be in the research room. 235 00:11:56,250 --> 00:11:58,300 Narrator: While this blood was being tested, 236 00:11:58,333 --> 00:12:01,366 a police officer was posted to guard the room, 237 00:12:02,000 --> 00:12:05,500 which technically was not yet a crime scene. 238 00:12:05,830 --> 00:12:09,160 The lab was not closed down when Annie went missing. 239 00:12:09,500 --> 00:12:10,183 Multi-million dollar research 240 00:12:10,216 --> 00:12:12,216 is being conducted in that facility, 241 00:12:12,250 --> 00:12:14,233 and there was no reason to close it down. 242 00:12:14,266 --> 00:12:17,266 Narrator: But the police presence didn't stop a lab worker 243 00:12:17,300 --> 00:12:19,830 named Raymond Clark 244 00:12:19,116 --> 00:12:22,316 from attempting to handle the bloodstained box of wipes, 245 00:12:22,350 --> 00:12:24,383 a potential piece of evidence. 246 00:12:25,160 --> 00:12:28,283 Raymond Clark entered the room, 247 00:12:28,316 --> 00:12:31,500 and he walked over near the cart, 248 00:12:31,830 --> 00:12:33,350 made some small talk with the officer, 249 00:12:33,383 --> 00:12:38,200 and then moved this bloody towel dispenser 250 00:12:38,233 --> 00:12:40,500 to a different part of the cart 251 00:12:40,830 --> 00:12:43,166 where the blood wouldn't be as obvious. 252 00:12:43,200 --> 00:12:47,266 Narrator: Raymond Clark was a 24-year-old lab technician. 253 00:12:47,300 --> 00:12:50,383 Like Annie, he was engaged to be married. 254 00:12:51,160 --> 00:12:52,366 Altimari: He was not a graduate student. 255 00:12:53,000 --> 00:12:54,316 He was a Yale employee. 256 00:12:54,350 --> 00:12:56,366 He basically took care of the animals, 257 00:12:57,000 --> 00:12:59,383 cleaned up after them, took care of them, in fact. 258 00:13:00,160 --> 00:13:02,183 So, he would've had access to every lab. 259 00:13:02,216 --> 00:13:06,000 Narrator: But Clark's past was not without some red flags 260 00:13:06,330 --> 00:13:07,183 for investigators. 261 00:13:07,216 --> 00:13:10,133 One of Ray's former girlfriends 262 00:13:10,166 --> 00:13:12,283 had actually reported domestic violence. 263 00:13:12,316 --> 00:13:14,150 So, there was a side of Raymond Clark 264 00:13:14,183 --> 00:13:18,160 that was not told to us up until we started digging. 265 00:13:18,500 --> 00:13:22,660 Narrator: Keycard activity showed Clark was in the G13 lab 266 00:13:22,100 --> 00:13:26,830 the same time as Annie, and they were alone. 267 00:13:26,116 --> 00:13:27,366 Raymond Clark entered that room 268 00:13:28,000 --> 00:13:31,100 and stayed in that room for approximately 46 minutes. 269 00:13:31,133 --> 00:13:34,200 Narrator: There was nothing particularly unusual about this, 270 00:13:34,233 --> 00:13:36,160 but since it appeared Clark 271 00:13:36,500 --> 00:13:39,266 might have been the last person to see Annie alive, 272 00:13:39,300 --> 00:13:41,316 he was brought in for questioning. 273 00:13:41,350 --> 00:13:47,160 Raymond Clark was very cooperative in the process. 274 00:13:48,250 --> 00:13:52,116 [ Fire alarm sounding ] Narrator: But now investigators were taking a closer look 275 00:13:52,150 --> 00:13:54,830 at Raymond Clark. 276 00:13:54,116 --> 00:13:55,366 And in the security footage, 277 00:13:56,000 --> 00:14:00,100 they found something haunting on the day Annie was killed. 278 00:14:00,133 --> 00:14:01,366 After the fire alarm, 279 00:14:02,000 --> 00:14:06,500 when every employee of the Amistad building was evacuated, 280 00:14:06,830 --> 00:14:10,330 Clark's behavior seemed highly suspicious. 281 00:14:10,660 --> 00:14:14,500 We actually saw Ray Clark exit the building, 282 00:14:14,830 --> 00:14:16,100 go across the street, 283 00:14:16,133 --> 00:14:18,283 and sit on a wall, 284 00:14:18,316 --> 00:14:21,830 and he looked distraught. 285 00:14:21,116 --> 00:14:23,166 He actually was sitting there 286 00:14:23,200 --> 00:14:27,283 and put his head down on his hands, 287 00:14:27,316 --> 00:14:29,233 and it's all captured on video. 288 00:14:29,266 --> 00:14:33,000 His face is actually in his hands and he's kneeling forward, 289 00:14:33,330 --> 00:14:34,350 and he actually looks like he almost passes out 290 00:14:34,383 --> 00:14:37,000 and falls into the street. So, he's definitely under 291 00:14:37,330 --> 00:14:38,266 a lot of stress in that video. 292 00:14:38,300 --> 00:14:41,233 Narrator: But what was Raymond Clark stressed out about? 293 00:14:41,266 --> 00:14:45,500 And was it a coincidence or something worse 294 00:14:45,830 --> 00:14:46,316 that he was acting this way 295 00:14:46,350 --> 00:14:50,233 just after Annie Le was murdered? 296 00:14:58,350 --> 00:15:01,660 Narrator: When Raymond Clark was first questioned about Annie Le, 297 00:15:01,100 --> 00:15:03,333 he said he had no idea what happened to her 298 00:15:03,366 --> 00:15:08,660 and that he and Annie were coworkers, nothing more. 299 00:15:08,100 --> 00:15:10,166 But on the day Annie was killed, 300 00:15:10,200 --> 00:15:13,283 his keycard showed him moving a lot 301 00:15:13,316 --> 00:15:19,160 between Annie's last known location, a lab called G13, 302 00:15:19,500 --> 00:15:21,200 and a seldom-used storage area 303 00:15:21,233 --> 00:15:25,500 called G22 just down the hall. 304 00:15:25,830 --> 00:15:28,100 Detective Insalaco had become convinced 305 00:15:28,133 --> 00:15:32,100 that the G22 storage room would connect Raymond Clark 306 00:15:32,133 --> 00:15:34,316 to what happened to Annie Le. 307 00:15:34,350 --> 00:15:36,266 I said, "Alright, here's what we're gonna do. 308 00:15:36,300 --> 00:15:38,250 We're gonna turn off the lights, we're all gonna get down 309 00:15:38,283 --> 00:15:41,000 real low to the ground, and we're gonna use our flashlight. 310 00:15:41,330 --> 00:15:42,250 I'm gonna side-light the floor." 311 00:15:42,283 --> 00:15:44,266 Narrator: On the floor of the storage room 312 00:15:44,300 --> 00:15:47,116 was the usual dust and debris, 313 00:15:47,150 --> 00:15:49,200 but there was also something else. 314 00:15:49,233 --> 00:15:53,333 I immediately saw a brown bead with a hole in it. 315 00:15:53,366 --> 00:15:56,830 Narrator: Why was this important? 316 00:15:56,116 --> 00:15:59,500 Because Annie was wearing a beaded necklace 317 00:15:59,830 --> 00:16:01,383 the last time she was seen alive, 318 00:16:02,160 --> 00:16:05,283 and the bead was found in a room Raymond Clark 319 00:16:05,316 --> 00:16:08,316 had gone in and out of 11 times, 320 00:16:08,350 --> 00:16:11,660 and Annie's keycard showed 321 00:16:11,100 --> 00:16:14,100 she had never swiped into this room herself. 322 00:16:14,133 --> 00:16:19,133 So finding a bead on the floor was huge. 323 00:16:19,166 --> 00:16:23,330 Narrator: Then, above the ceiling tiles near the storage room, 324 00:16:23,660 --> 00:16:26,330 investigators made more ominous findings. 325 00:16:26,660 --> 00:16:29,830 They found a sock with blood on it 326 00:16:29,116 --> 00:16:31,183 and a glove in a ceiling panel 327 00:16:31,216 --> 00:16:34,250 that they also sent to get tested for DNA. 328 00:16:34,283 --> 00:16:37,233 This was later found to have Annie's blood 329 00:16:37,266 --> 00:16:40,100 and DNA from Raymond Clark. 330 00:16:40,133 --> 00:16:44,266 More incriminating evidence was found in a nearby laundry bag 331 00:16:44,300 --> 00:16:46,100 that had never been searched. 332 00:16:46,133 --> 00:16:47,250 When I dumped it out, 333 00:16:47,283 --> 00:16:51,133 I automatically saw blue pair of sweatpants. 334 00:16:51,166 --> 00:16:55,166 I saw dark dried blood on those pants, 335 00:16:55,200 --> 00:16:58,500 and I just looked at it and I went, 336 00:16:58,830 --> 00:17:00,233 "There's his pants." 337 00:17:00,266 --> 00:17:04,333 Narrator: And those pants contained a mixture of Annie's blood 338 00:17:04,366 --> 00:17:09,216 and semen later matched by DNA to Raymond Clark. 339 00:17:09,250 --> 00:17:12,383 Even the pen, which had intrigued investigators 340 00:17:13,160 --> 00:17:16,366 ever since Annie's body was found, implicated Clark. 341 00:17:17,000 --> 00:17:21,330 That pen really started to connect things together for us. 342 00:17:21,660 --> 00:17:23,183 Raymond Clark habitually signed 343 00:17:23,216 --> 00:17:27,316 in and out of laboratory logbooks with a green pen. 344 00:17:27,350 --> 00:17:29,183 But in the middle of the day, 345 00:17:29,216 --> 00:17:32,233 just about the time Annie disappeared, 346 00:17:32,266 --> 00:17:34,266 he switched to a black pen. 347 00:17:34,300 --> 00:17:38,383 Detectives believe Raymond Clark dropped the pen by mistake 348 00:17:39,160 --> 00:17:43,233 as he stuffed Annie Le's body behind the bathroom wall. 349 00:17:47,330 --> 00:17:50,316 Dadio: All of us that worked on the case were 100% confident 350 00:17:50,350 --> 00:17:54,116 that Raymond Clark was the person that murdered Annie Le. 351 00:17:54,150 --> 00:17:57,316 Narrator: Further proof came from a physical check of Clark. 352 00:17:57,350 --> 00:18:01,283 It showed he had recently been in a violent altercation. 353 00:18:01,316 --> 00:18:05,166 He had minor cuts on his head and face. 354 00:18:05,200 --> 00:18:08,350 Dadio: You want to know what compels somebody 355 00:18:08,383 --> 00:18:12,100 to violently attack a coworker 356 00:18:12,133 --> 00:18:14,100 with no provocation. 357 00:18:14,133 --> 00:18:16,333 Narrator: To this day, no one knows, 358 00:18:16,366 --> 00:18:19,660 and Raymond Clark isn't talking. 359 00:18:19,100 --> 00:18:23,660 He was a foot taller than Annie and more than twice her weight. 360 00:18:23,100 --> 00:18:26,266 Prosecutors believe this was an unplanned attack 361 00:18:26,300 --> 00:18:29,283 and that she didn't stand a chance. 362 00:18:29,316 --> 00:18:33,200 However it started, the evidence is clear. 363 00:18:33,233 --> 00:18:37,100 Raymond Clark strangled and sexually assaulted Annie 364 00:18:37,133 --> 00:18:40,500 in the G13 lab. 365 00:18:40,830 --> 00:18:44,266 During this altercation, blood, later matched to her, 366 00:18:44,300 --> 00:18:47,830 landed on objects in the lab, 367 00:18:47,116 --> 00:18:48,283 including the box of wipes 368 00:18:48,316 --> 00:18:51,350 that Raymond Clark later tried to hide. 369 00:18:51,383 --> 00:18:53,333 In an attempt to cover up the crime, 370 00:18:53,366 --> 00:18:56,266 investigators theorized he may have used 371 00:18:56,300 --> 00:18:58,316 the large rolling tables in the building 372 00:18:58,350 --> 00:19:02,183 to move Annie's body to a more isolated area -- 373 00:19:02,216 --> 00:19:06,000 the storage lab known as G22. 374 00:19:06,330 --> 00:19:08,200 His keycard showed a flurry of activity 375 00:19:08,233 --> 00:19:11,266 between Annie's lab and that storage area 376 00:19:11,300 --> 00:19:16,300 just after Annie's keycard activity stopped. 377 00:19:16,333 --> 00:19:19,216 His clothes with his DNA 378 00:19:19,250 --> 00:19:21,283 were covered with her blood 379 00:19:21,316 --> 00:19:24,333 and were later found in a laundry bag. 380 00:19:24,366 --> 00:19:27,350 He was able to get Annie to a nearby bathroom 381 00:19:28,000 --> 00:19:30,233 and stuffed her body behind the wall, 382 00:19:30,266 --> 00:19:32,366 where he dropped his green pen 383 00:19:33,000 --> 00:19:36,500 covered with his DNA. 384 00:19:36,830 --> 00:19:39,183 Raymond Clark was able to hide Annie's body, 385 00:19:39,216 --> 00:19:41,233 at least for a while, 386 00:19:41,266 --> 00:19:43,183 but he couldn't hide the evidence 387 00:19:43,216 --> 00:19:46,233 that tied him to her murder. 388 00:19:46,266 --> 00:19:48,316 Altimari: It was a woman that had a lot to live for, you know? 389 00:19:48,350 --> 00:19:50,200 She was about to get married, she was clearly 390 00:19:50,233 --> 00:19:52,216 a brilliant graduate student. 391 00:19:52,250 --> 00:19:56,830 Who knows what she would've gone on to study or become, 392 00:19:56,116 --> 00:19:58,166 and her life was cut short. 393 00:19:58,200 --> 00:20:00,350 It was a senseless murder. 394 00:20:00,383 --> 00:20:05,160 Narrator: In March of 2011, Raymond Clark pled guilty 395 00:20:05,500 --> 00:20:09,330 to first-degree murder and sexual assault. 396 00:20:09,660 --> 00:20:14,500 He was sentenced to a minimum of 44 years in prison. 397 00:20:14,830 --> 00:20:17,383 But one question, perhaps the biggest of all, 398 00:20:18,160 --> 00:20:20,166 remains unanswered to this day. 399 00:20:20,200 --> 00:20:23,660 The "why?" His side of what had happened, 400 00:20:23,100 --> 00:20:24,383 and the "why?" 401 00:20:25,160 --> 00:20:26,100 Stollo: The state's case 402 00:20:26,133 --> 00:20:29,830 was that he sexually assaulted her 403 00:20:29,116 --> 00:20:31,350 and then killed her to cover up that crime. 404 00:20:31,383 --> 00:20:34,250 Narrator: Investigators describe Annie's murder 405 00:20:34,283 --> 00:20:38,330 as one of the most bizarre they've ever encountered, 406 00:20:38,660 --> 00:20:40,116 and they're grateful for the science 407 00:20:40,150 --> 00:20:44,500 that finally revealed what happened to her. 408 00:20:44,830 --> 00:20:46,160 Stollo: Forensic evidence was very important. 409 00:20:46,500 --> 00:20:49,330 It was what made the case. 410 00:20:49,660 --> 00:20:52,660 It allowed a quick suspect to be developed, 411 00:20:52,100 --> 00:20:54,166 it allowed a quick arrest to be made, 412 00:20:54,200 --> 00:20:58,000 and it made an incredibly strong case for the state. 413 00:20:58,330 --> 00:21:00,350 Dadio: Annie would've changed the world with her research 414 00:21:00,383 --> 00:21:02,660 and for what she wanted to do 415 00:21:02,100 --> 00:21:04,133 to make the world a better place.
