wrong. >> he finds deep problems with the process in general. >> the entire thing is designed to make you look back, from the moment they get you in custody. what they want is that you accept responsibility for having committed a crime. that's what interrogation is about. >> but the austin police contend their ambition is uncovering the truth. a goal they say they begin pursuing the moment they receive this 911 call from jennifer's mother. >> please hurry, please hurry! >> the address of the emergency? ma'am, hello? >> police are directed to the home of an erratic national merit scholar finalist and drug dealer, romantically involved with both laura hall and

jennifer cave. after failing to hear from her daughter, jennifer's mother and her fiancee have forced their way into colton's apartment, encountering a grisly sight in the bath tub. >> her head was severed and her hands in the attempt to remove any possibility of obtaining any dental work or fingerprint. so there's a saying that's common amongst homicide detectives, which i actually have inscribed on the bracelet on my wrist which means let the dead teach the living. our job as homicide detectives are to speak for the dead because they've got a family that's going to have to continue on without them. >> to pursue that mission, the detective begins exploring 6th

street, the epicenter of austin as night life and the party scene that brought lauren hall and colton together. >> colton was dating jennifer cave at the time. once colton revealed to her the body was in the bath tub, laura hall may have taken part in the mutilation of the body, as far as stabbing jennifer cave in the upper torso, stabbing her on the upper side of her face and firing the round in the cranial vault of her head. >> six days later, authorities tracked laura and colton to a hotel room in a mexican town. but laura isn't arrested. instead police advise her family to pick her up and take her home. >> she was still subject of the investigation but we weren't clear as to her level of involvement. so at that point she was not a

suspect. >> colton is charged with jennifer's murder and brought to a local detention center to be interviewed. >> that's absolutely your right to do, okay? >> investigators then drive to laura's parents homes but when they turn on their tape recorder, laura appears unwilling to help them build a case against colton. >> he wasn't a sicko. i don't believe he did it. i really don't. >> in fact, laura describes the trip to mexico not as a flight from justice but a romantic vacation. >> i was very excited that he wanted me to go on a trip with him. i was like, i love this guy.

he's so cute. i didn't think twice. >> but three days later detectives capitalize on another opportunity to question laura, instructing her to come to austin police headquarters to pick up her impounded car, then escorting her inside the box, or the interrogation room. >> i hope you didn't find any inconsistencies. >> there were a lot of inconsistenci inconsistencies. >> we knew her involvement was a lot greater than she led to us believe. so you have nothing else to tell us? you're not going to change your statements or anything? >> mark gilcrest, the lead detective, already knows he's going to put her in jail. there's already a warrant. >> you don't want to talk to me

without your attorney. >> but he plays a game with her until she says i want a lawyer. >> if you're saying i might be in some kind of trouble. >> read that. laura ashley hall, you're under arrest for hindering apprehension. >> since the last conversation, police have been carefully scrutinizing this image of the pretty government major driving her boyfriend over the border. that's enough to charge her in assisting colton's escape, but investigators suspect her involvement goes much deeper and continue to pursue more serious charges. >> oh, my god. oh, my god, what's going to happen? >> you're going to go to jail. >> what did i -- oh, my god. what do you want to know? >> i want to know the truth. >> if a person is not under arrest, you don't have the right to have an attorney present during any questioning. she was free to leave. once they informed her she was

under arrest, the whole ball game changed and she's entitled to an attorney. and if she invoked her right at this point, the interview would have been terminated. >> what we can deal with right now is do you want to make things right and talk to us and give as you statement, or do you want to get up and go to jail? >> hoping to distance herself from any wrong doing, laura is about to tell detectives her account. >> when he had the knife up, he licked it, he put his tongue in the blood. >> but can anyone believe her version of events?

i asked him about it. he wouldn't tell me who had been there. he told me to shut up, quit being a ho about things. >> is that normal for him to talk to you like that? >> sometimes. >> she denied having any knowledge of the murder at all. bit by bit, she would give a little bit of detail, enough to let us know there was more information still to be gleaned from the interview. >> i knew about it. >> okay. >> i knew there was a body in the bathtub. >> as we're interviewing somebody, we'll have them go and lay out their story in chronological order. we'll go back and ask them in reverse order.

austin, texas, august 26th, 2005. away from the swirl of activity on 6th street, university of texas undergraduate laura ashley hall finds herself alone in an interrogation room contemplating the possibility of prison. police have already charged laura with hindering apprehension for driving boyfriend colton pitonyak into mexico after he kills his own girlfriend, 21-year-old jennifer cave. investigators also suspect laura of dismembering the corpse in the bathtub, cutting off the head and the hands to prevent identification. >> didn't say anything about

handling the body. >> i didn't touch the body. >> didn't say anything about handling things -- >> i didn't touch the hacksaw. >> when did we talk about a hacksaw? >> we didn't. i read it in the paper. >> do you believe everything you read in the paper? >> no. >> how did you know there was a hacksaw involved? >> he told me he went and bought the hacksaw. he confessed that. >> laura is in the box for more than eight hours tweaking, revising, and sometimes inventing. >> he said that three people came into the apartment, one of them was -- they had guns. they came in shooting at them. he said he killed three people. >> did he say where the rest of them was supposed to be? >> yeah. >> what did he say? >> he said he dumped them. >> yet in between the inaccuracies, detectives say

they find a few nuggets of truth they need to further the case against colton. >> there was a bit of relief after the interrogation, because we were able to gather details that we would not have otherwise. >> despite her description of colton pitonyak as an intimidating drug user, who at one stage in laura's story runs his tongue down a bloody knife, she refuses to testify at his 2007 trial for jennifer's murder. >> mr. pitonyak said he doesn't remember how it happened. when he essentially came out of the influence of alcohol and drugs, his friend jennifer cave was dead in his apartment. as far as all of the mutilation and all of the aftermath, he blamed all of that on laura. >> colton is convicted of murder and sentenced to 55 years. and sometime prior to her own

trial, laura tattoos his name on her ankle, a bewildering choice her lawyer attributes to her instability. >> i think that laura is bipolar. there's a picture of her coming into the trial, and she looks like she's miss america. coming into the trial she's smiling, all bad affect. tell me, is that relevant to the determination of whether she committed a crime. >> because she opts not to take the stand at either trial, the best barometer of her character can be found on the interrogation tapes. >> colton owed about $2,000 to the asian mafia. he thought they were going to kill him over the money. >> yet prosecutors never allowed

jurors to hear these statements. >> i've never seen the state miss an opportunity to air an interrogation. >> i know it's embarrassing but i have to ask, was there intercourse or oral sex? >> uh-huh. >> what could be more important to show a jury than the callous disregard for the fact you're having sex feet away from the dismembered body of the young girl, but they don't do it. the question is, why not? the flip side of that question is it's callousness of the detectives who acted in reckless disregard to the common bounds of human decency. >> we did not introduce it at trial because we felt like it was manipulative and self-serving and we would like to question her about her story. they are confident that both the machete used in the dismemberment and the gun fired

will convince jurors she mutilated her rival for colton's affections. on september 1st, 2007, laura is convicted of tampering with evidence, for cutting up jennifer's body and hindering apprehension for driving colton to mexico. nonetheless, because of a procedural dispute regarding the penalty phase, laura decides to appeal her five-year sentence. this time bill bishop is prepared to let jurors hear the defendant's words, not from the interrogation but a series of recorded jailhouse phone conversations. >> i'm pretty mad. there's a lot of people that are going to pay for this. i hate them with a passion. >> among the targets of laura's anger, jennifer cave's mother. >> she's going down one way or another, that bitch. >> i remember the words. they are burned into my memory. i think the next question that was played in that conversation was what about that [ bleep ]

damn judge? she responds, when i get out of jail this time, i'm going to march down to his office and i'm going to bitch slap that mother [ bleep ] is what she said. of course the judge is sitting there listening, too. >> in july 2010, laura's appeal results in her sentence being doubled to 10 years. for detective david fugate, the information culled from the interrogation of laura ashley hall ultimately fulfills his mission of giving voice to the dead. >> the bottom line is to find out the facts of the case. it's not necessary all about the conviction, it's about finding the truth. >> coming up -- >> please don't ask me these questions. >> a florida teen is told he helped kill his elderly relatives. >> if he didn't really remember

he was just a redneck boy that went hunting and fishing and loved being in the woods with all his friends. >> he considers the homicide victims, 84-year-old patrick depalma and his 79-year-old wife, evelyn, likable but distant relatives. >> the depalmas were my great uncle and aunt. edwin depalma was my uncle's sister. the children and i went over there and scrubbed her house and did all kinds of stuff for her. >> on october 28th, 2006, an intruder drives up to the depalmas remote home in the small community. >> they were stabbed and cut multiple times. mrs. depalma is located in the

we've got two, we use them so often. i'll get this one cranked up. >> you're going to have to reload the questions. >> computers, i think as we all know, although they are of great assistance, sometimes they are a problem. i've seen that happen in other investigations by other law enforcement agents. if the question is was that a ploy by the examiner, i don't believe it was. i don't have any evidence to indicate that it was. >> still, alex seems bothered by the mishap. >> i'll have you out of here before you know it. alex, do me a favor. take the microphone and hold it in front of your mouth. don't clip it there and hold it just like that. >> i've never heard of a voice analysis. i was doing everything i could to try to clear up whatever their thoughts were. i had no doubts on the answers i give him. i was extremely confident.

now he says he visited the depalma home with two acquaintances to commit a burglary. the story is consistent with the theory detective phil laken has been advancing in the interview room. >> i wouldn't have done anything like that, which i think is why they came up with the two other suspects. and they gave me something, but i didn't want to take it. >> do you know how many there were? >> there was a couple. he was trying to get drugs, find something. >> what else were you trying to find? >> i think keith was trying to get drugs and find something. all keith looked forward to was money. >> i think he heard what he wanted to hear.

i was outside. >> where were you outside? >> in keith's car. >> for what? when you went back inside the house, tell me what you knew, what you saw, what you heard. >> he was hollering a little bit. >> and what were they saying while they were hollering? >> something wasn't supposed to happen. >> what wasn't supposed to happen? >> he was killing them. >> i guess mainly, from watching tv, like to piece together how i would think a murder scene would go down. >> sometime during the night, prosecutor pete mcgreeno receives a call from the sheriff's office. >> i said, well, don't arrest him for the murder. perhaps at best he may be an accessory. >> i wasn't there. please stop asking me these

questions. >> bostick said, i don't know. by my count was 285 times. i can't or i don't remember 163 times. >> you've got to tell me something went bad. >> i don't know. >> what the detective felt were admission to certain factual aspects were only made after the detective directly or indirectly provided that information to mr. bostick. >> that's all right. you've remembered quite a bit so far. and you're doing a good job. >> are my parents here? >> i'll check right now. >> by about 11:00 that night, my ex-husband showed up, banging on the doors for someone to let us in, and get to my son.

the detectives looked at me and said, he was there. he was at the crime scene. when it happened. are and i said, he's a good boy. you know, he doesn't deserve this. and he said, ted bundy's mother said he was a good boy, too. >> the county attorney's office declined to discuss the case with msnbc. when alex's father finally gains access to the interrogation room, the teen has been there for more than eight hours. >> one thing he's always been able to do is keep me calm. >> i didn't believe i had anything to do with it until he told me that they had all this evidence on me, that i was there. >> that's all kind of a ploy. >> but alex's parents are about to deliver the worst news possible. >> you're being charged with -- >> with?

>> murder. >> i'm sorry. we're just in the middle of it. we'll have the attorney here. and do as much as we can as soon as we can. >> i'm calling again right now. >> he said, what are they going to do to me? and i wiped his tears, and i was just like, i don't know. >> because he was 16 at the time of the murders, alex is transported to a juvenile detention facility. where he's placed in solitary confinement. >> i knew there was only two things that could happen. either they were going to figure out that they were wrong and i was going to be okay, or i was going to sit in jail for a while. >> there was a meeting later on in the morning with the sheriff's office. they were of the belief that the interview of him was sufficient,

and that further dna testing would prove that. and i can remember saying, well, it's his dna, if it isn't there, there's no case there. >> in fact, despite the long interrogation, dna would eventually link the depalmas not to alex, but to an ex-marine. a stereo, vacuum cleaner and set of keys stolen from the couple would also be found in his possession. >> he did say when asked, that bostick was not involved in the murder. >> this is reinforced by phone records, that show alex in tampa about 35 miles from the depalma home at the time of the crime. >> i know of no evidence that ties him to the homicides.

>> in 2010, hernando county jury confers, convicting robert jarden of the double homicide, when robbing the depalmas' property. alex is released from juvenile defense when prosecutors refused to present his case to a grand jury. authorities expunge the arrest from his record, clearing the way for alex to pursue his dream of joining the u.s. military. >> i've tried to put it behind me. it wasn't -- i guess you could say an important lesson in my life. that's kind of how i try to keep it. i don't like to complain negatively about any person or any event. and if i watched it, i have a feeling i'd have a different opinion.

it's the place where lies unravel and alibis crumble. >> why wouldn't you abduct them? tell me that. >> the interrogation room, or as cops call it, the box. >> remember, he doesn't like you, he doesn't trust you, and he doesn't respect you. you've got to overcome those three things before you're going to get a confession. >> in california, a seasoned detective takes us along for a psychological showdown with a suspected serial rapist. >> what was it that pushed you into the idea of forcing sex on women? >> and in arkansas, a boy tells us about being 12 and on the other side of the table. >> you killed yo s
