what did he do? what did he touch? >> they have problems here, 'cause this crime scene was managed very poorly. >> people have made lots of accusations about the crime scene. >> police interviews, forensic tests. >> peter manso wrote about the investigation in his book "reasonable doubt" >> the police here have not had to deal with a murder in maybe a generation, two generations, three generations, who knows. these people are not trained to handle a murder scene. >> a blanket was thrown over the victim. that contaminated the body. >> i can tell you one of the rules of protocol is not to take a piece of evidence from a crime scene and cover the body with it, even for decency's purposes. >> people were moving things around and touching things. >> the floor wasn't taped off for safe ways to walk on the crime scene. >> there was so many fingerprints from everybody touching everything. >> there's a huge difference between csi and cape cod csi. >> the district attorney michael o'keefe told us first responders have to assess the threat and treat the injured. no crime scene is pristine. this one was better than many. >> while the crime scene was not pristine, they found critical evidence. >> dna. sperm and saliva. >> we believe that christa worthington was involved in an intimate relationship with a person prior to or relatively contemporaneous with her death. >> investigators and worthington's family say they hope the $25,000 reward they are now offering will help establish the identity of that person, presumably the last to see her. about that mystery man, the district attorney will only say he is not necessarily worthington's killer. >> all we'd like is a resolution and some closure for christa, and for her daughter ava. >> the police and the district attorney were desperate. they had not solved this case, so they decided to do a very unusual thing. >> investigators took the controversial step of launching what's called a dna dragnet. they asked all of truro's roughly 800 male residents to voluntarily give dna samples. >> who did the police question? everybody. and they did so indiscriminately. so literally hundreds of people, myself included. >> the post office, the filling station coffee shop, and the highland grill are all locations in truro where police asked men this morning to use this kit and voluntarily give saliva samples containing their dna. >> they approached you and asked to be able to swab you. men only. >> almost everyone in town was a suspect. i mean, have you ever heard anything so ridiculous in all of your life? i mean, it's like, are you kidding me? >> the reaction was swift. >> this dna sweep is what catapulted the case to a national profile. >> a national debate invigorated. police tried to find the killer by asking every man in a small town to submit dna. civil bibry were outraged. >> it wasn't so much to get the dna, it was to find out who's reluctant to give it. >> the district attorney says investigators will look more closely at those who do not cooperate. >> i would just say to any member of the public that they should have no trepidation about cooperating with the police. >> this is big brother. this is 1984-type stuff. >> after three years of investigation, the police finally get this dna break and they make an arrest, but they arrest someone that no one would have expected. >> we were stunned, especially since the person who was arrested was not anybody we had ever heard of. it's like he came out of nowhere. how do you chase what you love with moderate to severe rheumatoid arthritis?

"what do you think about your son being arrested for murder?" >> that's chris, see him? he's 7 years old here. he wanted to be friends with everybody. >> i'm roy mcgowan, i'm the father of chris mcgowan. >> i said to myself, "christopher is a player. he's not a murderer." >> when i read about the knife in the woman's chest, stuck it so hard where it stuck to the floor. i said, "there's no way in the world that's chris." christopher loved his job. he always wanted to move up, wanted to get his own truck and he wanted to partner with his boss, so i thought that was great. >> i met with chris mccowen. in my mind, he was not a person capable of this type of crime. there was no motive. >> chris's daughter was the same age as ava. >> this is not a cold, deliberate, calculating person. this is not a person who had a reason to do harm to another. >> there are a number of people who don't believe that christopher mccowen could have or would have done this and that includes his boss. >> they've got the wrong person. this person just would not do that. when he would get in an argument with another driver over some silly thing, and chris would just walk away from it. he would not fight. >> his appearance was outside the norm for outer cape residents. over six feet, dark skinned, muscular, the automatic thought i think that chris would be a scary or intimidating man. when you got to know him, he was so much the opposite. as far as i'm concerned, chris has no violence in him. >> 33-year-old christopher mccowen had no comment as he arrived at orleans district court this morning on his arraignment for charges of raping and murdering 46-year-old christa worthington. >> christopher mcgowan is charged with murder, but he's also charged with rape. and that turns out to be a very controversial charging decision. >> between the time of the murder and the arrest of chris mccowen three years later, there was not a word about rape. not one word about rape. >> they were never looking for a rapist here. they wanted to know who her boyfriends were, because they knew there was semen in her. >> the sperm sample that they found, it was degraded, that the sperms had no tails. it might have been a couple of days old. it might have been from not on the night of the murder but from prior to the murder. >> there was a rush to judgment. you had a black garbage man. the cape is not very heterogeneous. >> nationally, black people make up 13.5% of the population. cape cod, you know, the home of jack kennedy, the figure is 1.2%. >> there was no question that there was a dna match, but there was, in a lot of people's minds, a question of whether there could have been a consensual relationship. >> he says that he had a number of consensual relationships with women who were on his route when he was collecting garbage. >> chris was quite the ladies' man. he was very charismatic. >> he had many, many girlfriends. he was pretty much of a stud. >> the question is, would christa worthington have a consensual sexual relationship with the african-american trash collector? some say, well, why not? >> christa's need for love and affirmation was so great that it wouldn't surprise me in the least if she had slept with him. >> despite mccowen being well liked, when police did a background check what they found was disturbing. mccowen had a criminal history for grand theft and burglary and had served time. most importantly for this case, he had five restraining orders out against him from women who he knew. the allegations ranging from grabbing someone's neck, strangling, pushing, scaring. >> restraining orders, i think when the general public look at them and go, "he did what?" you have to look at the nature of this homicide. i mean, stabbing somebody, you've got to literally be right on top of them. does he have the capacity to do that? there's nothing in his history that would suggest that. i mean, typically people who commit these types of homicides they've used knives before. he doesn't really sort of fit a person that would commit this type of homicide. >> 33-year-old christopher mcgowan was arraigned today in barnstable superior court. charged in the felony of murder in the first degree. >> how do you plead, guilty or not guilty? >> not guilty. >> not only does christopher mccowen say he didn't kill christa worthington but he points the finger directly at someone else. >> good afternoon, sir. in a nice loud voice tell us your name. >> jeremy frazier. probiotics, and fiber, it could be wearing on you. tell your doctor what you've tried and how long you've been at it. linzess works differently from laxatives. linzess treats adults with ibs with constipation or chronic constipation. it can help relieve your belly pain and lets you have more frequent and complete bowel movements that are easier to pass. do not give linzess to children less than six, and it should not be given to children six to less than eighteen. it may harm them. don't take linzess if you have a bowel blockage. get immediate help if you develop unusual or severe stomach pain, especially with bloody or black stools. the most common side effect is diarrhea, sometimes severe. if it's severe stop taking linzess and call your doctor right away. other side effects include gas, stomach-area pain, and swelling. ask your doctor if 90 days of linzess may be right for you. thanks, i used masterpass. master...pass?

>> somewhat spread apart. >> reporter: it's not just that she was stabbed to death. she was also horribly beaten, and there's bruises all over her body. >> the photos were very graphic. i think those photos helped us to get the reality of the crime scene, to get the reality of a murder was committed. >> the defendant was completely indifferent to her suffering, and that's based on the statement that you'll hear that he made. >> a major component of this case was christopher mcgowan's statement given to the police during a very long interrogation. the prosecution relied upon it. >> christopher mason, the lead detective from the massachusetts state police, was a professional police officer who presented very well, and he was credible. >> and did you have occasion to interview a christopher mccowen? >> yes, i did. >> the first two times that mccowen was questioned by the authorities, he basically denied knowing her, but then they hand him the dna report. and everything changes. >> and i informed him that the report from the state police crime lab concluded that it was his dna on the body of christa worthington. >> all right. and after you showed him that report, slid it across the table to him, what did he do next, sir? >> mr. mccowen then stated, it could have been me. >> it could have been me. >> it could have been me. >> so mccowan is saying it could have been me who had sex with christa, because it was his dna. >> some of the strongest evidence against christopher mccowen is his statement. i mean, he denies knowing her, and then his semen is inside her. i mean, hello? and then his statement gets more and more incriminating. >> in his statement to police, chris mccowan first says that christa asked him to help dispose of a christmas tree. >> mr. mccowen explained to me that he had had a discussion with christa worthington that evening in that house about getting rid of the christmas tree. >> that friday night, is that correct? >> that's correct. >> mccowen's statement to the police progressed to the point where he admitted that he had consensual sex with christa worthington on the living room floor. >> his response was, i [ bleeped ] the [ bleeped ] out of her. i don't know. >> is that a direct quote, sir? >> yes, it is. >> reporter: he changes the story, and introduces another person, a friend of his that he would socialize with. >> he goes on to say, i wasn't the only one there. jeremy frazier and i went up there. >> jeremy frazier becomes a player in this case. he's young, under 21, knows chris mccowan because they the same circles. >> jeremy frazier admits that he was with chris mccowen earlier in the night, the night that christa worthington was killed, and there's video in this bar where you can see them. >> reporter: in his statement to police, mccowen says that he and frazier leave the juice bar and go to christa's house. >> mr. mccowen stated that he gave jeremy frazier directions, and that jeremy frazier drove him -- drove them to christa worthington's residence. >> mccowen claims that he asked jeremy to drive him to christa's so he could have sex. he didn't want to drive himself. he was afraid of getting busted for drunk driving. he was wasted. >> he then indicated to me that -- that christa worthington was startled to see us. he stated that he probably said something like, i'm tipsy. i just wanted to get some -- real quick. mr. mccowen informed me, she was cool with it. >> mccowen's account was the he went up there, and he and christa got it on and jeremy meanwhile was taking her possessions. >> he indicated that following the sex, christa worthington confronted jeremy frazier about -- about what he was doing. he and jeremy frazier then left the residence, and that christa worthington followed them out. >> at which point, again this is the mccowen account, christa comes barreling out of the house and starts screaming at frazier, you [ bleep ], you thief. i want me stuff back. >> what did he say, sir? >> he stated, jeremy lost it, and i just followed suit. it was pandemonium. >> they get into a fight, which starts outside. they get into it in the driveway. >> he stated that jeremy beat her. he beat her. he said, we put the boots to her. he said, i still can hear her hit the ground. she hit the ground hard. he states that jeremy frazier then dragged her under the arms and dragged her into the house. >> frazier was beating on her, and he punched her in the face, and in the chest, and he said it was frazier who took a knife, and stabbed christa through the chest. >> i asked mr. mccowen, well, what would he say if the troopers in truro, and i determined that jeremy frazier was somewhere other than truro on that evening? >> and what was his response to that, please, sir? >> his response was, then it's all -- then it's all on me if jeremy can account for his time. >> that was the final version that emerged from the six-hour interview. >> you have all of those versions, which was from, i did have sex with her, to being around, but wasn't involved in the homicide, to literally sounds like being in the same room when the homicide occurred. he changes the version, but he never puts a knife in his hand. >> he never vacillated from the fact that he never killed christa worthington. >> the defense said he cannot be trusted. >> the statement is not worth the paper it's written on. >> led him to self confession. >> he was putty in their hand. i need an insulin that fits my schedule. ♪ tresiba® ready ♪ (announcer) tresiba® is used to control high blood sudon'tt diabetic ketoacidosis, during episodes of low blood sugar, or if you are allergic to any of its ingredients. don't share needles or insulin pens. don't reuse needles. the most common side effect is low blood sugar, which may cause dizziness, sweating, confusion, and headache. check your blood sugar. low blood sugar can be serious and may be life-threatening. injection site reactions may occur. tell your prescriber about all medicines you take and all your medical conditions. taking tzds with insulins like tresiba® may cause serious side effects like heart failure. your insulin dose shouldn't be changed without asking your prescriber. get medical help right away if you have trouble breathing, fast heartbeat, extreme drowsiness, swelling of your face, tongue, or throat, dizziness, or confusion. ask your health care provider if you're tresiba® ready. covered by most insurance and medicare plans. ♪ tresiba® ready ♪ shsaturday is the last day toore anget $15 kohl's cashday for every $50 spent! plus - take an extra 20% off! save on cashmere sweaters sleepwear for the family and bedding. saturday at kohl's. you may be at increased risk for pneumococcal pneumonia, that can take you out of the game for weeks, even if you're healthy. pneumococcal pneumonia is a potentially serious bacterial lung disease that in severe cases can lead to hospitalization. it may hit quickly, without warning, causing you to miss out on the things you enjoy most. prevnar 13® is not a treatment for pneumococcal pneumonia... it's a vaccine you can get to help protect against it. prevnar 13® is approved for adults to help prevent infections from 13 strains of the bacteria that cause pneumococcal pneumonia. you should not receive prevnar 13® if you have had a severe allergic reaction to the vaccine or its ingredients. if you have a weakened immune system, you may have a lower response to the vaccine. the most common side effects were pain, redness and swelling at the injection site, limited arm movement, fatigue, headache, muscle pain, joint pain, less appetite, vomiting, fever, chills, and rash. help protect yourself against pneumococcal pneumonia. ask your doctor or pharmacist about prevnar 13®. ♪ ♪ ♪ ♪ the all new 2018 camry. toyota. let's go places. >> at the courthouse is actually a sculpture of lemuel shaw. >> it was lemuel shaw who formulated, more than anyone else, the doctrine of reasonable doubt. >> if these jurors think it is reasonable to believe that someone else might have done it, that's reasonable doubt and that's an acquittal for chris mccowen. >> the defense said that christopher mccowen's statements to the police could not be trusted. >> the statement is not worth the paper it's written on. >> mccowen was spoken to for about six and a half hours. that interrogation was reduced to a 27-page report by state trooper chris mason. >> the interview was about six hours. is that right??

>> yes. from the pubic area, there was various colored fibers. most of them were blue and white. >> chris mccowen was not alleged to have been wearing anything that was blue and white on the evening of the homicide. but he was with somebody who was wearing a blue and white sweater. and that was jeremy frazier. >> reporter: jeremy frazier took the stand as a witness for the prosecution. >> are you a member of any gang or group?

♪ >> gerard smith was a very well respected member of the community in truro. >> he was taking his morning constitutional on depot road. >> it was saturday -- the day before christa worthington's body was found. and smith saw a car tearing out of her driveway. >> the car was coming down here, didn't even put on brakes, it went right out through here, and kept on going. just went 'woosh.' like that, and that was why it drew my attention. i turned around to see who was driving the car. >> according to gerard smith, the driver of that car was a white man, not a black man. >> gerard smith was a compelling witness. >> can you describe the person? >> he was caucasian. he was a little dark, but he was not black. >> it wasn't really given great weight by the commonwealth, because it didn't fit the scenario that they went to trial on. it's like, well then who could that have been? >> one thing is clear. that person who killed christa worthington or had something to do with killing christa worthington was white, and he wasn't chris mccowen. >> at trial, bob george presented a different scenario for what happened the night christa was murdered. he says mccowan never went to the house after the juice but he was there the day before on thursday that was garbage pickup day. >> he says he was on his route on a thursday, christa called him into her home because she wanted him to remove her christmas tree. he says that one thing leads to another and they do have this encounter, but that it's consensual. >> and he didn't rape her because there's no evidence of rape. >> chris says he didn't tell the police because she wanted it to be kept private. he said she wanted it to be a secret. >> it's absolutely possible that he had sex with her on thursday, was not there on friday, somebody else killed her, and then that's your bad guy, not him. >> there is nothing to suggest on her body that she was violently sexually assaulted. >> the autopsy did not use the word rape. >> there is no bruising. there is no tearing. >> there is no evidence of any violent sexual contact with the victim in this case in the form of injury, is there? >> there's no report of injury, right. that's correct. >> he says she came on to him, and that was just too much for some people to believe that christa worthington, this vassar-educated woman, would have sex with a garbage collector. >> as soon as they see the black garbage man, it's rape. >> the truth is that he went up there looking for sex, christa worthington confronted him and it got very ugly. >> i went into closing argument believing i had, at the very least, a case of reasonable doubt. >> the 12 members of the jury sat in this box. there was only one african-american woman on the jury. so it wasn't really considered to be much of a jury of his peers. >> the government's case is based on assumptions that aren't true. and it's based on incorrect and ignored evidence. >> mr. george has tried to play the race card during this trial and said that the police couldn't accept the idea of consensual sex between a black garbage man and christa worthington. and i would suggest to you this defendant would be facing the same evidence and the same trial with the same jury if he were white. >> the jury in this case reported themselves deadlocked. deliberated for eight days before coming to a verdict. >> after many days the verdict comes in. it's a stampede up here to the courtroom. >> we the jury to return the following verdict. guilty of first-degree. guilty of murder in the first-degree in extreme atrocity, and cruelty, and also, felony murder. >> after the verdict was delivered, mccowen, of course, was devastated. and he started to cry. >> i watched the verdict come in. having been a prosecutor, i always look at the defendant for a reaction. this reaction was completely unusual. he shook his head, vehemently, and cried. >> i'm peopling sorry for the worthington family, her daughter and her. i never meant for this. all this time, i have been innocent. >> the court, hereby extends you to be in prison for and during the term of your natural life without the possibility of parole. >> three life terms. holy moly. >> three jurors submitted affidavits charging they were coerced into their guilty verdicts by other racist jurors. >> soon after the trial, bob george hears from a few of the jurors who had information that was potentially a game changer. >> i immediately filed a motion to set aside a verdict as a result of racial bias in the jury room. >> it is incredibly unusual to have a hearing to look back at how a jury reached a verdict that it did. it almost never happens. >> according to these jurors, two other jurors repeatedly described mccowen as big and black. >> the "black" man this and the "black" man that and he's so big and he scares me when he looks at me. >> peter manza aligned himself with the trial but he was researching the book. >> this is part of the files from my book. >> in researching his book called "reasonable doubt", he recorded an interview with the sole black juror who felt racism was at play during the deliberations for some of the majors. >> they all are attacking me every day anyway, all of them, like i'm the only one in that room who gave this man the benefit of the doubt that -- you know, suggests that maybe he's innocent. i don't know if he did it, but i know it hadn't been proven to me. that's all i know. show me the evidence. >> race did not play a part at all in deciding christopher mcgowan's guilt or innocence. it had no effect on the verdict. there's just no way around the dna. >> the judge found that the words big and black were just e descripti descriptions. >> chris has never spoken before, but chris wants to get his story out there. >> this is a global tel link prepaid call from christopher mccowan, an inmate at a massachusetts correctional institution. >> hi, chris. >> hello? >> so, you had sex with her on the thursday, and then she ends up dead on a friday. can you understand why people think that that's odd? take a deep breath in and exhale. aflac. and a gentle wave-like motion. liberate your spine. aflac. and reach, toes blossoming. not that great at yoga. ya but when i slipped a disc, he paid my claim before i knew it. so he had your back. yup. in just one day, we process, approve and pay. one day pay. only from aflac. bthe less stuff i have, myto carry the better.k. with surface pro, i have one device that does everything. technology has really changed how i do this job. on pacific rim: uprising our characters are 250 ft. tall. where in the heck are you gonna land this big robot? pulled up a satellite image and there is like a giant bullseye, robots here! i feel very proud of what i bring to the screen. i have the greatest job in the world. >> christopher mccowen has been in prison for 11 years now. he's maintained his innocence the entire time. >> chris didn't testify. so you've never really heard from chris as to what he said actually happened. >> at this point, chris wants to get his story out there. chris wants to explain. chris regrets not testifying. >> we're sitting in a hot room instead of in a prison interviewing your client in person. why is that? >> the department of corrections wouldn't allow an interview on camera with chris. >> this is a global tel link prepaid call from -- >> christopher mccowan. >> hi, chris. >> hello? hey. >> let's go back to how this all started, okay? >> being a garbage man, you know, i get to go by everybody's houses and you know get to talk to them briefly. she asked me to come in the house and to look at her christmas tree. >> were you attracted to her? >> she had something with her. standing there, that close in her vicinity with her you know one thing just led to another and -- >> what do you mean, one thing led to another? >> it just like it was just a mutual thing between two people, i guess, and we started kissing. then we winded up, ended up having -- having sex. >> so how many times were you intimate with christa? >> just one time. >> you had sex with her on the thursday. >> right. >> and then she ends up dead on a friday. can you understand why people think that that's odd? that you must have killed her? >> there's a lot of speculation on the exact timeline of when she was killed, but i didn't have nothing to do with it. >> you've told your defense that the police manipulated you. what do you mean by that? >> because they kept on switching everything up. i was so intoxicated off of all of them drugs that i really didn't know what the hell was going on. >> were you at christa's house on the night of friday, january 4th, 2002? >> no, no. >> after the juice bar, where did you go? >> we went to an after hours party. >> and what did you do after that? >> i went straight home. >> do you ever remember going to christa's house with jeremy? >> no. >> but you also named jeremy as christa's killer. >> that's what they said that i did. i didn't do that. >> so you don't remember telling the police that jeremy stabbed christa? >> no. >> the district attorney michael o'keefe made a statement to abc news, which said, "the evidence against christopher mcccowen and only christopher mccowen for the rape and murder of christa worthington was overwhelming. the jury unanimously convicted the defendant. the supreme judicial court then exhaustively reviewed the case and upheld the conviction. >> the defense is always believing there is more evidence that suggest a new trial. >> at the trial the defense tried to suggest that jeremy frazier was very close, cozy almost, with the state police. >> the defense says that jeremy frazier got special treatment from the police. >> you see the phone numbers there on the paper? >> on the night of the murder, jeremy frazier got a call from the state police barracks. >> now, it says that you received a phone call from someone at the state police barracks here in south yarmouth at 12:03. you see that, don't you? >> yes. >> why would somebody from the massachusetts state police be calling jeremy frazier on a friday night, when he's out partying? and, if you believe the defense, probably on his way to truro at that moment. > do you have any memory whatsoever of talking to a state police trooper -- >> no, i did not talk to no state police. >> he said, "i don't talk to the police. i didn't talk to the police." but phone records don't lie. >> much was made about this mysterious phone call to jeremy. the defense wants you to believe that jeremy frazier was some informant and that he's somehow getting a pass on a murder charge because he gives information on marijuana or drug cases? i would suggest to you reject that. >> what's interesting in looking at the telephone records of jeremy frazier, he keeps calling a 978 exchange repeatedly on january 4th. including around the time of the murder. >> see these highlighted phone calls to a beeper pager? >> yes. >> jeremy frazier says it was actually him calling his own pager because he'd lost it and he was trying to find it. >> do you see the pager here that says 978? >> that's my pager, yes. >> you told the police that when they talked with you? >> that's my pager. >> we suspect that that is not the case. and if that's not his pager number, that certainly raises a lot of questions. >> did you ever run these numbers to find out who was carrying that pager? >> i don't believe a subpoena was done for that pager number, no. >> they didn't consider him a possible suspect. and so, his phone records, to them, weren't that relevant. >> i've asked for subpoenas to show a couple of things. to show cell phone towers to see where he was that particular evening, but also to see the identity of the person who's number that traces back to. >> this is really a last-ditch and long-shot effort by mccowen's attorney to try to find some sort of new evidence that might get him a new trial. >> are you optimistic about your attorney's new motion for a new trial? >> i don't deserve to be in here, so yes. >> now when you were questioned by the police you told -- >> or anything because she asked me not to say anything because she didn't want people to know about her personal business. >> didn't you realize that, perhaps, they would find out that you had had sex with her? >> i didn't have nothing to hide. if they were to ask me if i had any of kind of intercourse with her, i would have told them, "yeah," but they never asked me that question. >> what do you think happened to christa? >> that's a good question, i wish i knew. >> whether or not you believe that christopher mcgowan is an innocent man or a convicted killer, the tragedy here is that ava worthington was deprived of a relationship with a mother who clearly loved her and adored her. >> one of the images about this trial that sticks with people is of the little 2 1/2-year-old ♪ ♪ ♪ ♪ the all new 2018 camry. toyota. let's go places. when you ache and haven't you're not you. tylenol® pm relieves pain and helps you fall fast asleep and stay asleep. we give you a better night. you're a better you all day. tylenol®. virtual reality- all virtually useless without a new computer. all i see is darkness. give intel 8th gen core to power all the latest tech. togwe pick upgo bigger the best values of the year, and get the best brands for our next big project. right now, get this husky mechanic's tool set for just $99. only at the home depot. when you add a line to the cricket unlimited 2 plan. plus, get great deals on lg smartphones when you switch. all on a network that covers over 99% of americans cricket wireless. something to smile about. whentrust the brand doctors trust for themselves. nexium 24hr is the number one choice of doctors and pharmacists for their own frequent heartburn. and all day all night protection. when it comes to frequent heartburn, trust nexium 24hr. whget more bang for your buck with $15 kohl's cash for every $50 spent! earn it on everything even our biggest brands - all week long! the more you shop the more kohl's cash you'll get - no limit! so when you give joy, you get joy! all this week - only at kohl's. >> i think there is so much mystery that still surrounds this case. this case still has fog around it that needs to be cleared. >> we often say, cases as they get older, do not get better. memories fade and more importantly evidence disappears. >> mccowen's attorney has been told that now, this many years after the fact, jeremy fraser's phone records had been destroyed. they don't exist any more. >> that is a significant blow to this defense and this motion for a new trial. >> can you at least confirm if you knew christopher mccowen? >> i don't know anybody. >> since the trial, jeremy frazier's gotten himself in a lot of trouble. >> jeremy frazier's been charged with rape of a child with force, of course, that's gonna be of interest to mccowen's defense team -- >> i'd asked for an entry of a plea of "not guilty." >> this tells us that jeremy frazier may be a horrible person. but it doesn't tell us that he killed christa worthington. >> in the 15 years since her death, i think about her regularly. if i were to tell christa's daughter who she was, i would say she is a person of great loyalty and intelligence and generousty and humor. >> ava's little with a bunch of curls here. >> christa was still alive. when that picture was taken. >> that little girl who was two and a half at the time is now 18. >> she's a college freshman. she was raised by one of christa's friends. she did get to see tony jackett and susan and her brothers and sisters growing up. >> she's very popular and she seems to be well adjusted. and we're very happy for that. >> she's fun. she's very affectionate. very smart. and she's just very well-rounded, wonderful girl. amyra did a wonderful job raising her. >> it's unfortunate that christa didn't have the opportunity to watch her grow into a young, lovely woman. it will the forever be marked by the fact of her death. >> ultimately, i don't know that we will ever really know what really happened at 50 depot road that night. ♪ a shark attacks a diver in monterey county. hear from a witness and new hear from a witness and new details about what helped ♪ it's time for the ultimate sleep number week hear from a witness and new detailon the only bed that adjusts on both sides to your ideal comfort your sleep number setting. and snoring?
