00:06:24,310 is that it was a very dysfunctional household. 86 00:06:24,413 --> 00:06:27,482 In the early days, Mary Day, middle sister Kathy, 87 00:06:27,586 --> 00:06:30,965 and Sherrie were in and out of a foster home. 88 00:06:31,068 --> 00:06:33,862 Their mother could not take care of them. 89 00:06:33,965 --> 00:06:38,034 Sherrie was adopted by the foster family. 90 00:06:38,137 --> 00:06:43,379 We were separated when I was six years old. 91 00:06:43,482 --> 00:06:46,793 Mary and Kathy were returned to their mother Charlotte. 92 00:06:46,896 --> 00:06:50,172 By this time, Charlotte had married William Houle. 93 00:06:50,275 --> 00:06:52,241 And the couple had two kids of their own. 94 00:06:55,034 --> 00:06:58,310 Houle was a soldier. 95 00:06:58,413 --> 00:07:02,068 The family moved around a lot from base to base. 96 00:07:02,172 --> 00:07:04,793 At one point, detectives say Mary's stepfather 97 00:07:04,896 --> 00:07:07,551 had been reportedly physically abusing her. 98 00:07:11,448 --> 00:07:15,344 Children's protective services had taken custody of Mary. 99 00:07:15,448 --> 00:07:17,586 She was eventually turned back over to the family. 100 00:07:17,689 -->

officer. 205 00:13:47,034 --> 00:13:50,034 He and Charlotte were still together. 206 00:13:50,137 --> 00:13:52,862 She agreed to talk with local detectives 207 00:13:52,965 --> 00:13:57,275 about the daughter who vanished so long ago. 208 00:13:57,379 --> 00:13:58,931 You don't have whips and chains, do you? 209 00:13:59,034 --> 00:14:00,344 Oh, absolutely not. 210 00:14:00,448 --> 00:14:01,206 [CHUCKLES] 211 00:14:01,310 --> 00:14:02,551 Darn. 212 00:14:02,655 --> 00:14:04,206 I remember watching the interview 213 00:14:04,310 --> 00:14:09,172 and realizing that she had something to tell us. 214 00:14:09,275 --> 00:14:12,068 You know, life is full of regrets. 215 00:14:12,172 --> 00:14:18,000 If you go back and say, if I did this and this and this. 216 00:14:18,103 --> 00:14:20,931 Her body language and then her sinking down in her chair 217 00:14:21,034 --> 00:14:22,758 and saying words to the effect of, 218 00:14:22,862 --> 00:14:26,344 sometimes you do things in your past and it comes back. 219 00:14:26,448 --> 00:14:28,862 I knew that there was something there. 220 00:14:28,965 --> 00:14:31,172 When aws the last time you heard from Mary? 221 00:14:31,275 --> 00:14:32,206 '81. 222 00:14:32,310 --> 00:14:34,068 The last time she ran away. 223 00:14:34,172 --> 00:14:37,724 Charlotte said Mary running away was no big deal. 224 00:14:37,827 --> 00:14:40,689 She did it all the time. 225 00:14:40,793 --> 00:14:43,793 Oh, what a mess. 226 00:14:43,896 --> 00:14:46,655 It was like trying to get a nightcrawler out of a wormhole. 227 00:14:46,758 --> 00:14:48,103 Just grabbing it, and it was gone. 228 00:14:48,206 --> 00:14:50,137 Grabbing it, it was gone. 229 00:14:50,241 --> 00:14:53,827 How many times did she run away? 230 00:14:53,931 --> 00:14:56,758 All these questions, I can't answer. 231 00:14:56,862 --> 00:14:57,827 OK. 232 00:14:57,931 --> 00:15:01,758 When you was back in California, did you guys 233 00:15:01,862 --> 00:15:04,310 take any kind of steps to find her? 234 00:15:04,413 --> 00:15:06,862 We should have. 235 00:15:06,965 --> 00:15:08,344 We should have. 236 00:15:08,448 --> 00:15:09,620 But you didn't. 237 00:15:09,724 --> 00:15:12,896 My husband said we filed a police report with the Salinas 238 00:15:13,000 --> 00:15:14,655 Police Department. 239 00:15:14,758 --> 00:15:17,827 If we did, I don't remember. 240 00:15:17,931 --> 00:15:20,896 There is no record of a report. 241 00:15:21,000 --> 00:15:25,482 I couldn't understand a parent, number one, not reporting 242 00:15:25,586 --> 00:15:27,241 their child as runaway. 243 00:15:27,344 --> 00:15:30,034 But number two, treating this case, 244 00:15:30,137 --> 00:15:31,931 the status of their missing daughter, 245 00:15:32,034 --> 00:15:33,793 as basically no big deal. 246 00:15:33,896 --> 00:15:35,448 It didn't seem to really concern them. 247 00:15:38,034 --> 00:15:44,344 They were not really, really surprised at us being there. 248 00:15:44,448 --> 00:15:47,482 Detective Bertaina later questioned Mary's stepfather, 249 00:15:47,586 --> 00:15:49,034 William. 250 00:15:49,137 --> 00:15:51,655 I just asked him, tell me about the last time 251 00:15:51,758 --> 00:15:52,827 that you saw Mary. 252 00:15:52,931 --> 00:15:55,448 He told me that, well, he was going room 253 00:15:55,551 --> 00:15:56,965 to room checking on the kids. 254 00:15:57,068 --> 00:16:00,689 And he discovered Mary wasn't in the bedroom. 255 00:16:00,793 --> 00:16:01,793 He told Charlotte. 256 00:16:01,896 --> 00:16:02,482 She panics. 257 00:16:02,586 --> 00:16:03,137 He panics. 258 00:16:03,241 --> 00:16:04,586 Call the police. 259 00:16:04,689 --> 00:16:06,586 And he knew I wasn't buying that. 260 00:16:06,689 --> 00:16:09,310 I said, William, she runs away all the time. 261 00:16:09,413 --> 00:16:10,620 Why did you panic? 262 00:16:10,724 --> 00:16:12,000 I never got a good response. 263 00:16:14,965 --> 00:16:17,655 The detective pressed Houle and brought up 264 00:16:17,758 --> 00:16:19,827 the story of the sick dog. 265 00:16:19,931 --> 00:16:22,586 And he said five or six times, you know what she did? 266 00:16:22,689 --> 00:16:23,965 She poisoned my dog. 267 00:16:24,068 --> 00:16:25,413 And I was really angry. 268 00:16:25,517 --> 00:16:27,517 She tried to run out of the house. 269 00:16:27,620 --> 00:16:29,172 I didn't want her to go, so I caught her 270 00:16:29,275 --> 00:16:32,137 before she got out of the front door. 271 00:16:32,241 --> 00:16:34,689 She was kicking me, punching me. 272 00:16:34,793 --> 00:16:38,275 So I pushed her. 273 00:16:38,379 --> 00:16:41,931 And when he's doing this, he's making a-- 274 00:16:42,034 --> 00:16:42,965 A choking? 275 00:16:43,068 --> 00:16:45,103 Yeah, a gesture with his hand. 276 00:16:45,206 --> 00:16:47,413 And it's like a hand strike that I've seen before. 277 00:16:47,517 --> 00:16:48,620 It's a martial art technique. 278 00:16:48,724 --> 00:16:51,379 So I ask him, where did you hit her with that? 279 00:16:51,482 --> 00:16:53,965 And he said, well, in the upper chest. 280 00:16:54,068 --> 00:16:55,862 And I said, could it have been the throat? 281 00:16:55,965 --> 00:16:58,000 And he said, well, it may have slipped off 282 00:16:58,103 --> 00:17:00,034 and hit Mary in the throat. 283 00:17:00,137 --> 00:17:01,965 I wanted to know on a scale of 1 to 10 284 00:17:02,068 --> 00:17:06,103 his anger when he had done this, when he had struck Mary. 285 00:17:06,205 --> 00:17:11,103 And he said on a scale of 1 to 10, I was a 15. 286 00:17:11,205 --> 00:17:14,034 I said, you're this angry. 287 00:17:14,137 --> 00:17:17,758 I think you may have killed her. 288 00:17:17,862 --> 00:17:20,275 And he looked at me and said, no. 289 00:17:20,378 --> 00:17:22,448 I didn't kill her. 290 00:17:22,550 --> 00:17:24,550 But the next day, my wife Charlotte 291 00:17:24,655 --> 00:17:28,931 told me that that night, she saw Satan in my eyes. 292 00:17:29,034 --> 00:17:32,724 And she said I was possessed by a demon. 293 00:17:32,827 --> 00:17:35,310 And then it dawned on me that he's 294 00:17:35,413 --> 00:17:38,310 admitting but not admitting that he killed her. 295 00:17:38,413 --> 00:17:40,241 And I said, OK, William, I believe you. 296 00:17:40,344 --> 00:17:41,206 You didn't kill her. 297 00:17:41,310 --> 00:17:45,000 But what about that demon inside of you? 298 00:17:45,103 --> 00:17:48,931 Could that demon have killed Mary? 299 00:17:49,034 --> 00:17:50,896 He looked at me and he said, yes. 300 00:17:51,000 --> 00:17:52,689 The demon could have killed her. 301 00:17:52,793 --> 00:17:54,068 When he walked out, did you think 302 00:17:54,172 --> 00:17:56,137 you were letting a killer go? 303 00:17:56,241 --> 00:17:57,000 Yeah. 304 00:17:57,103 --> 00:17:59,551 Yeah. 305 00:17:59,655 --> 00:18:01,379 Joe said, yeah, we don't have a body. 306 00:18:01,482 --> 00:18:04,896 But he said, this guy came so close to confessing 307 00:18:05,000 --> 00:18:07,517 that it was as close as he's ever had anybody come. 308 00:18:07,620 --> 00:18:09,758 Is that enough to go to a prosecutor 309 00:18:09,862 --> 00:18:12,137 and say, I don't know if we're ever going to get the body, 310 00:18:12,241 --> 00:18:15,448 but we have a lot of the pieces of the puzzle? 311 00:18:15,551 --> 00:18:17,310 Yeah. 312 00:18:17,413 --> 00:18:19,827 The DA wasn't ready to file at that time. 313 00:18:19,931 --> 00:18:21,275 Did you think there was enough? 314 00:18:21,379 --> 00:18:24,310 I thought there was probably enough. 315 00:18:24,413 --> 00:18:27,931 I was not worried really, because I thought 316 00:18:28,034 --> 00:18:31,206 we are building the case here. 317 00:18:31,310 --> 00:18:35,310 And then just as the detective's confidence was growing, 318 00:18:35,413 --> 00:18:38,896 the case took an unexpected turn. 319 00:18:39,000 --> 00:18:43,620 Remember, police had no record of Mary Louise Day as an adult. 320 00:18:43,724 --> 00:18:46,620 There were no credit cards, no driver's license 321 00:18:46,724 --> 00:18:50,758 or ID recorded anywhere. 322 00:18:50,862 --> 00:18:56,689 There hadn't been a trace of Mary in more than two decades. 323 00:18:56,793 --> 00:19:01,379 Until police in Phoenix, Arizona, made a traffic stop. 324 00:19:01,482 --> 00:19:02,275 I got a phone call. 325 00:19:02,379 --> 00:19:03,000 I was at home. 326 00:19:03,103 --> 00:19:04,344 I left work. 327 00:19:04,448 --> 00:19:07,724 And he told me, hey, Captain, he says, are you sitting down? 328 00:19:07,827 --> 00:19:09,379 And I said, what happened? 329 00:19:09,482 --> 00:19:11,655 He said, no, he says, just going to let 330 00:19:11,758 --> 00:19:14,068 you know that Phoenix Police Department in Arizona 331 00:19:14,172 --> 00:19:15,172 pulled over a car. 332 00:19:15,275 --> 00:19:18,344 And they say that they found Mary Day. 333 00:19:22,586 --> 00:19:25,793 What do you make of William and Charlotte's stories? 334 00:19:25,896 --> 00:19:28,103 Hear Charlotte's unusual response 335 00:19:28,206 --> 00:19:31,103 to police searching for her missing daughter on Facebook 336 00:19:31,206 --> 00:19:32,137 at 48 Hours. 337 00:19:40,689 --> 00:19:42,310 November 2003. 338 00:19:42,413 --> 00:19:45,000 Phoenix, Arizona. 339 00:19:45,103 --> 00:19:47,758 It was a routine traffic stop. 340 00:19:47,862 --> 00:19:50,068 A pickup truck with stolen plates. 341 00:19:50,172 --> 00:19:55,655 When police ran the IDs of the passengers, one of them hit. 342 00:19:55,758 --> 00:19:57,724 A woman named Mary Day. 343 00:19:57,827 --> 00:19:59,586 He said, Joe, guess what? 344 00:19:59,689 --> 00:20:00,931 Mary Day has been found. 345 00:20:01,034 --> 00:20:03,896 And I was stunned. 346 00:20:04,000 --> 00:20:07,862 Investigators had put Mary Day into a missing persons database 347 00:20:07,965 --> 00:20:10,172 long ago. 348 00:20:10,275 --> 00:20:14,241 She identified herself with a Phoenix identification card. 349 00:20:14,344 --> 00:20:18,931 Or Arizona state identification card. 350 00:20:19,034 --> 00:20:21,896 Back in California, Detective Joe Bertaina 351 00:20:22,000 --> 00:20:24,965 felt like a ghost had just appeared. 352 00:20:25,068 --> 00:20:27,827 In his mind, Mary Day had been murdered 353 00:20:27,931 --> 00:20:31,724 more than 20 years earlier at the home of her parents. 354 00:20:31,827 --> 00:20:35,931 You talked to William and Charlotte in April of 2003. 355 00:20:36,034 --> 00:20:36,965 Yeah. 356 00:20:37,068 --> 00:20:39,965 And then seven months later or so, a woman 357 00:20:40,068 --> 00:20:43,965 named Mary Louise Day just falls out of the sky. 358 00:20:44,068 --> 00:20:44,620 I was stunned. 359 00:20:47,551 --> 00:20:51,137 His boss, Steve Cercone, could not believe it. 360 00:20:51,241 --> 00:20:54,448 Joe went down there, and he met her. 361 00:20:54,551 --> 00:20:56,206 And he sent a picture of her. 362 00:20:56,310 --> 00:20:58,000 And we went, what? 363 00:20:58,103 --> 00:20:59,344 Wait a minute. 364 00:20:59,448 --> 00:21:00,137 No. 365 00:21:00,241 --> 00:21:01,068 All right, all right. 366 00:21:01,172 --> 00:21:02,344 It looked like it could be her. 367 00:21:02,448 --> 00:21:05,034 And I said, wait a minute, all these other bits 368 00:21:05,137 --> 00:21:06,413 of circumstantial evidence-- 369 00:21:06,517 --> 00:21:08,724 The father almost confessing to something. 370 00:21:08,827 --> 00:21:12,551 Almost confessing to the murder of a little girl. 371 00:21:12,655 --> 00:21:17,689 And now here was this woman 700 miles away with a valid Arizona 372 00:21:17,793 --> 00:21:18,862 State ID. 373 00:21:18,965 --> 00:21:21,896 Strangely, that ID had been issued only three 374 00:21:22,000 --> 00:21:24,689 weeks earlier, while the homicide investigation was 375 00:21:24,793 --> 00:21:25,931 underway. 376 00:21:26,034 --> 00:21:28,689 Well you must have found the timing awfully suspicious. 377 00:21:28,793 --> 00:21:30,655 Yes, it was very suspicious. 378 00:21:30,758 --> 00:21:32,965 [SIREN BLARING] 379 00:21:33,068 --> 00:21:35,482 When Detective Bertaina went to Phoenix, 380 00:21:35,586 --> 00:21:37,724 the woman he was sure had been murdered 381 00:21:37,827 --> 00:21:40,344 told him she had run away from her mother 382 00:21:40,448 --> 00:21:43,896 Charlotte and stepfather William when she was a teenager. 383 00:21:44,000 --> 00:21:46,379 She'd basically lived under the radar. 384 00:21:46,482 --> 00:21:49,172 And by her wits ever since. 385 00:21:49,275 --> 00:21:55,551 But she seemed hesitant, and her story seemed sketchy. 386 00:21:55,655 --> 00:21:58,758 Later in a phone call, Mary told Bertaina 387 00:21:58,862 --> 00:22:01,413 she had some awful memories. 388 00:22:01,517 --> 00:22:04,310 Did you want to talk about what happened that last night? 389 00:22:04,413 --> 00:22:05,482 It hurts. 390 00:22:05,586 --> 00:22:06,413 I'm sure it does. 391 00:22:06,517 --> 00:22:09,241 But what happened that last night? 392 00:22:09,344 --> 00:22:10,586 I'm so confused anymore. 393 00:22:10,689 --> 00:22:12,310 I don't know what's real or not. 394 00:22:15,448 --> 00:22:20,586 I remember he kept slamming my head into the tub and it hurt. 395 00:22:20,689 --> 00:22:22,413 Is that when you started bleeding? 396 00:22:22,517 --> 00:22:26,068 I started bleeding, and hit my head onto the coffee table. 397 00:22:26,172 --> 00:22:27,241 I think I blacked out. 398 00:22:27,344 --> 00:22:29,310 Maybe that's why I can't put all the pieces together 399 00:22:29,413 --> 00:22:30,793 to tell you. 400 00:22:30,896 --> 00:22:35,068 But she didn't remember anything about the sick dog. 401 00:22:35,172 --> 00:22:36,482 Was that troublesome to you? 402 00:22:36,586 --> 00:22:39,413 That was, yeah. 403 00:22:39,517 --> 00:22:42,965 Investigators say it was hard to pin down much of anything 404 00:22:43,068 --> 00:22:45,103 about her past two decades. 405 00:22:45,206 --> 00:22:48,758 They began to wonder if the woman with the freshly minted 406 00:22:48,862 --> 00:22:51,827 ID was really who she claimed to be. 407 00:22:51,931 --> 00:22:54,068 You refused to call her Mary Louise Day. 408 00:22:54,172 --> 00:22:55,758 We called her Phoenix Mary. 409 00:22:55,862 --> 00:22:58,172 In phone conversations, Phoenix Mary 410 00:22:58,275 --> 00:23:02,344 was sounding increasingly frustrated. 411 00:23:02,448 --> 00:23:04,448 Can I throw one question at you, if you don't mind? 412 00:23:04,551 --> 00:23:05,448 Go ahead, Mary. 413 00:23:05,551 --> 00:23:06,965 If you would have found my body, how 414 00:23:07,068 --> 00:23:11,344 were you going to be able to prove who the hell I was? 415 00:23:11,448 --> 00:23:12,689 DNA. 416 00:23:12,793 --> 00:23:16,206 Oh, so since I'm still alive, y'all can't prove who I am? 417 00:23:16,310 --> 00:23:19,758 There's no record of you ever being anywhere. 418 00:23:19,862 --> 00:23:24,206 It's like you have an existing up until now. 419 00:23:24,310 --> 00:23:27,241 So I'd be better off if I'm just dead and then y'all can do that 420 00:23:27,344 --> 00:23:28,551 detecting from there. 421 00:23:31,482 --> 00:23:34,413 I said, all right, let's get a DNA test on this woman. 422 00:23:34,517 --> 00:23:37,241 Let's let her prove that she's the daughter of Charlotte. 423 00:23:37,344 --> 00:23:40,241 We're going to disprove that she's married, of course. 424 00:23:40,344 --> 00:23:44,413 Because there's no way that her DNA is going to match. 425 00:23:44,517 --> 00:23:47,724 Except it did match. 426 00:23:47,827 --> 00:23:48,862 I nearly fell on the floor. 427 00:23:48,965 --> 00:23:50,206 I couldn't believe it. 428 00:23:50,310 --> 00:23:57,448 The DNA came back positive to being a daughter of Charlotte. 429 00:23:57,551 --> 00:24:00,862 The case was closed. 430 00:24:00,965 --> 00:24:05,517 Sherrie invited her long lost sister to move in with her. 431 00:24:05,620 --> 00:24:08,724 In most cases, that would be the end of the story. 432 00:24:08,827 --> 00:24:12,517 But not in this case. 433 00:24:12,620 --> 00:24:14,310 So now DNA matches. 434 00:24:14,413 --> 00:24:15,344 Case closed. 435 00:24:15,448 --> 00:24:18,655 Yeah, well, if it were that simple, right? 436 00:24:18,758 --> 00:24:21,172 Once Phoenix Mary moved in, Sherrie 437 00:24:21,275 --> 00:24:23,482 started to have her own doubts. 438 00:24:23,586 --> 00:24:27,034 The first thing I noticed was it sounded 439 00:24:27,137 --> 00:24:31,275 like she had some weird Midwestern Southern accent. 440 00:24:31,379 --> 00:24:32,655 It's weird to me. 441 00:24:32,758 --> 00:24:35,275 The detectives had noticed that, too. 442 00:24:35,379 --> 00:24:38,586 That's an interesting dialect you have, Mary. 443 00:24:38,689 --> 00:24:39,965 What do you mean? 444 00:24:40,068 --> 00:24:42,137 I don't know if I've ever quite heard that particular manner 445 00:24:42,241 --> 00:24:43,275 of speaking. 446 00:24:43,379 --> 00:24:46,103 Then y'all still trying to prove who I am, huh? 447 00:24:46,206 --> 00:24:48,310 Yes, ma'am, we are. 448 00:24:48,413 --> 00:24:52,862 Phoenix Mary also said she never used her real name. 449 00:24:52,965 --> 00:24:55,931 Nobody knows me as Mary. 450 00:24:56,034 --> 00:24:58,034 I gave that name up years ago. 451 00:24:58,137 --> 00:24:59,724 What name would they know you by? 452 00:24:59,827 --> 00:25:01,758 Monica Devereaux. 453 00:25:01,862 --> 00:25:04,206 It's a name she said she made up. 454 00:25:04,310 --> 00:25:08,448 I did notice that she had magazines in the name of Monica 455 00:25:08,551 --> 00:25:10,896 Devereaux. 456 00:25:11,000 --> 00:25:15,379 Sherrie's sister Kathy was also unnerved. 457 00:25:15,482 --> 00:25:15,896 No. 458 00:25:16,000 --> 00:25:16,724 That's not Mary. 459 00:25:16,827 --> 00:25:17,379 Why? 460 00:25:17,482 --> 00:25:19,586 What makes you so sure? 461 00:25:19,689 --> 00:25:22,241 Something's off. 462 00:25:22,344 --> 00:25:25,586 You're telling me that your gut is saying it's not her. 463 00:25:25,689 --> 00:25:26,758 My gut. 464 00:25:26,862 --> 00:25:29,482 She says the woman claiming to be Mary didn't even 465 00:25:29,586 --> 00:25:32,689 remember that their birth father left them an inheritance they 466 00:25:32,793 --> 00:25:34,724 could collect at age 18. 467 00:25:34,827 --> 00:25:37,482 It was their shared escape plan, and they 468 00:25:37,586 --> 00:25:39,137 had a code word for it. 469 00:25:39,241 --> 00:25:41,965 Was there a code word or some sort 470 00:25:42,068 --> 00:25:45,586 of secret between you and Mary? 471 00:25:45,689 --> 00:25:46,758 Yeah, it was. 472 00:25:46,862 --> 00:25:48,517 It was called Mohawk. 473 00:25:48,620 --> 00:25:49,827 Mohawk was your secret word? 474 00:25:49,931 --> 00:25:50,413 Yep. 475 00:25:53,344 --> 00:25:55,344 And Mary did something else strange. 476 00:25:55,448 --> 00:25:58,931 She wrote a note to Detective Bertaina. 477 00:25:59,034 --> 00:26:00,413 She emailed Joe. 478 00:26:00,517 --> 00:26:03,724 And her email said something to the effect of, 479 00:26:03,827 --> 00:26:06,413 I've been lying to you about who I am. 480 00:26:06,517 --> 00:26:09,689 And that was new information. 481 00:26:09,793 --> 00:26:10,758 Oh my god. 482 00:26:10,862 --> 00:26:14,000 I said, oh, this is a whole new ball game. 483 00:26:14,103 --> 00:26:16,310 Still, the case remained closed. 484 00:26:24,586 --> 00:26:29,517 But then in 2008, Steve Cercone, now Seaside's police chief, 485 00:26:29,620 --> 00:26:32,482 got a phone call from investigators at the army base 486 00:26:32,586 --> 00:26:34,344 in Fort Ord. 487 00:26:34,448 --> 00:26:36,482 Another set of cadaver dogs had been 488 00:26:36,586 --> 00:26:40,862 working on an unrelated matter and had found something. 489 00:26:40,965 --> 00:26:42,724 Fort Ord was a huge place. 490 00:26:42,827 --> 00:26:46,413 And he said, look, we brought the cadaver dogs out here, 491 00:26:46,517 --> 00:26:48,586 and they went over hundreds of homes. 492 00:26:48,689 --> 00:26:51,827 And he said, we got a hit on one of the homes. 493 00:26:51,931 --> 00:26:55,758 You'll never believe who was living in this house. 494 00:26:55,862 --> 00:27:01,068 He said, William Houle and his family lived in this house. 495 00:27:11,827 --> 00:27:15,206 [MUSIC PLAYING] 496 00:27:20,137 --> 00:27:24,068 In 2008, cadaver dogs alerted near a second home 497 00:27:24,172 --> 00:27:25,517 where the Houles had lived. 498 00:27:25,620 --> 00:27:29,724 The house they had moved to shortly after Mary disappeared. 499 00:27:29,827 --> 00:27:31,965 So you're thinking that a body has 500 00:27:32,068 --> 00:27:35,000 been moved by this family from one location to another? 501 00:27:35,103 --> 00:27:36,965 Yeah. 502 00:27:37,068 --> 00:27:38,965 Once again, police dug. 503 00:27:39,068 --> 00:27:42,068 And once again, they came up short. 504 00:27:42,172 --> 00:27:44,172 Was Mary moved twice? 505 00:27:44,275 --> 00:27:47,034 Was this little girl who may have been killed back in 1981, 506 00:27:47,137 --> 00:27:49,758 was her body moved twice? 507 00:27:49,862 --> 00:27:51,551 Although the case had been closed, 508 00:27:51,655 --> 00:27:55,034 Cercone felt something was seriously wrong. 509 00:27:55,137 --> 00:27:56,034 I don't know. 510 00:27:56,137 --> 00:27:57,172 I don't know. 511 00:27:57,275 --> 00:28:00,379 But we have to investigate this. 512 00:28:00,482 --> 00:28:03,724 He hired Mark Clark, a retired homicide 513 00:28:03,827 --> 00:28:06,758 detective from nearby Salinas, California. 514 00:28:06,862 --> 00:28:10,862 Absolutely the most bizarre case I've ever come up against. 515 00:28:10,965 --> 00:28:13,655 Reviewing the evidence collected over the years, 516 00:28:13,758 --> 00:28:18,137 Clark was convinced there was a murder and missed 517 00:28:18,241 --> 00:28:19,413 opportunities. 518 00:28:19,517 --> 00:28:21,379 There are so many parts about this thing that 519 00:28:21,482 --> 00:28:23,689 could have solved this case back then that 520 00:28:23,793 --> 00:28:25,379 is really frustrating. 521 00:28:25,482 --> 00:28:29,000 He believes they let the parents off the hook too soon. 522 00:28:29,103 --> 00:28:31,034 Mom and Dad say she ran away, don't ever 523 00:28:31,137 --> 00:28:32,172 talk about her again. 524 00:28:32,275 --> 00:28:35,275 They tore up her pictures, threw away her clothes. 525 00:28:35,379 --> 00:28:36,379 And that was it. 526 00:28:36,482 --> 00:28:40,034 Most damning, he says, are Williams's own words. 527 00:28:40,137 --> 00:28:44,206 His comment was, I couldn't have killed Mary. 528 00:28:44,310 --> 00:28:46,586 My body would have done it, but it wouldn't have been me. 529 00:28:46,689 --> 00:28:48,689 It would have been that demonic personality, 530 00:28:48,793 --> 00:28:50,000 because I blacked out. 531 00:28:50,103 --> 00:28:52,689 Clark says he would have arrested William Houle. 532 00:28:52,793 --> 00:28:55,827 You just admitted tantamount to a homicide, 533 00:28:55,931 --> 00:28:58,758 and we're letting him go? 534 00:28:58,862 --> 00:29:02,482 Clark also focused on that shoe detectives found. 535 00:29:02,586 --> 00:29:06,137 Another detective asked Kathy about it. 536 00:29:06,241 --> 00:29:09,310 They first asked, did you guys ever wear canvas tennis shoes? 537 00:29:09,413 --> 00:29:11,344 And Catherine said Keds? 538 00:29:11,448 --> 00:29:14,172 And she said, yes, and pulled out the shoe. 539 00:29:14,275 --> 00:29:15,655 And it's pretty chewed up, but you 540 00:29:15,758 --> 00:29:19,068 can tell that it's a tennis shoe with a canvas body to it. 541 00:29:19,172 --> 00:29:22,103 And she said exactly that. 542 00:29:22,206 --> 00:29:26,275 And he consulted with the Body Farm, a renowned research 543 00:29:26,379 --> 00:29:30,206 facility that studies what happens when bodies decompose. 544 00:29:30,310 --> 00:29:34,344 He says they found soil samples consistent with a body being 545 00:29:34,448 --> 00:29:34,965 buried. 546 00:29:38,965 --> 00:29:41,068 What do you think happened to Mary Louise Day? 547 00:29:41,172 --> 00:29:46,551 She was killed in 1981 in probably around July. 548 00:29:46,655 --> 00:29:48,620 Clark believes the woman now claiming 549 00:29:48,724 --> 00:29:51,965 to be Mary Day is an imposter. 550 00:29:52,068 --> 00:29:55,586 There's just too many things that point to Phoenix Mary Day 551 00:29:55,689 --> 00:29:57,517 being somebody else. 552 00:29:57,620 --> 00:30:00,551 But what about that DNA test showing she's 553 00:30:00,655 --> 00:30:02,000 Charlotte Houle's daughter. 554 00:30:02,103 --> 00:30:05,827 Well, Mark Clark has a theory that he says explains it all. 555 00:30:05,931 --> 00:30:08,137 Even if it is a little farfetched. 556 00:30:08,241 --> 00:30:11,344 He says Charlotte Houle had another daughter, 557 00:30:11,448 --> 00:30:12,689 a secret daughter. 558 00:30:12,793 --> 00:30:15,965 Born before Mary and given up at birth. 559 00:30:16,068 --> 00:30:20,482 Clark believes Phoenix Mary is that secret daughter. 560 00:30:20,586 --> 00:30:25,655 So you think Phoenix Mary is the actual sister of Mary Louise 561 00:30:25,758 --> 00:30:29,000 Day, who goes missing back in 1981? 562 00:30:29,103 --> 00:30:30,862 Yes. 563 00:30:30,965 --> 00:30:33,758 He looked into Charlotte's background. 564 00:30:33,862 --> 00:30:36,137 There's some circumstantial evidence 565 00:30:36,241 --> 00:30:39,103 that Charlotte had a couple of marriages 566 00:30:39,206 --> 00:30:43,310 where she would be involved in extramarital affairs 567 00:30:43,413 --> 00:30:47,551 and become pregnant from those affairs. 568 00:30:47,655 --> 00:30:49,551 Clark says the Houles could have reached out 569 00:30:49,655 --> 00:30:51,137 to Charlotte's secret daughter when 570 00:30:51,241 --> 00:30:52,965 they felt they were in trouble. 571 00:30:53,068 --> 00:30:58,862 I believe she was somehow sought out by Charlotte and William 572 00:30:58,965 --> 00:31:04,724 to pose as Mary Day to avoid prosecution. 573 00:31:04,827 --> 00:31:07,241 It was an elaborate plot, he says. 574 00:31:07,344 --> 00:31:09,620 The Houles knew that police were investigating 575 00:31:09,724 --> 00:31:11,068 Mary's disappearance. 576 00:31:11,172 --> 00:31:14,827 And they asked her secret sister to assume her identity. 577 00:31:14,931 --> 00:31:19,344 Cercone says the Houles had the wherewithal to do it. 578 00:31:19,448 --> 00:31:22,103 What if they took the birth certificate of Mary, 579 00:31:22,206 --> 00:31:26,689 which they probably had, and the Social Security card from Mary. 580 00:31:26,793 --> 00:31:32,275 What if they gave those cards to the other sister and said, 581 00:31:32,379 --> 00:31:33,137 you're now married. 582 00:31:35,896 --> 00:31:38,965 Clark says the scheme put an end to the investigation 583 00:31:39,068 --> 00:31:42,758 and also put money in Phoenix Mary's pocket. 584 00:31:42,862 --> 00:31:44,000 There was an inheritance. 585 00:31:44,103 --> 00:31:48,344 We thought the motivation would be the inheritance. 586 00:31:48,448 --> 00:31:50,586 Because she could collect that inheritance. 587 00:31:50,689 --> 00:31:52,931 With accrued interest, that inheritance 588 00:31:53,034 --> 00:31:56,275 was now worth roughly $60,000. 589 00:31:56,379 --> 00:31:59,965 Sherrie helped Mary get her cut. 590 00:32:00,068 --> 00:32:02,620 We reached out to William and Charlotte Houle. 591
