>> absolutely. >> that's correct, your honor. i am innocent. >> as the case against scott peterson slowly made its way from arrest to trial, what really happened to laci peterson became a kind of televised courtroom theater. >> the defense is asking that the jury be sequestered for up to five months. >> the cast included legal celebrities like defense attorney mark geragos, who signed on to defend scott peterson. >> scott looks forward to finding out who did this to his wife and to his child, connor. >> and women's advocate -- >> thank you for coming today. i'm attorney gloria allred. to my right is amber frey. >> gloria allred, who erected a protective wall around the story's wild card, amber frey. >> amber was not going to be doing any interviews during the course of the case, even though so many people wanted to interview her. >> sure, yeah. wasn't she offered immense amounts of money to do covers and things like that? >> there were many offers to amber, if she would only provide an interview. but she needed to protect her testimony for the actual case. >> but altogether missing in the legal cacophony were the prosecutors. this was their first in-depth interview about the peterson case. during the trial, they often had to bite their tongues. >> your radio would go off in the morning, the radio alarm, and the little news blurb that you would hear on the pop radio station, whatever, would reference the case. they could say whatever they wanted, right? and it wasn't always necessarily true. >> good morning, your honor. >> good morning. >> in court, geragos wanted a change of venue, though just 90 miles or so from modesto, did anyone not know about the peterson case? >> how is he feeling about the move? >> he just wants the trial to take place so that people will be able to see what really took place. >> scott's mom assured reporters her son was innocent, but she couldn't have been very happy when everyone came to the courthouse and saw a local billboard a local radio station bought right across the street. man or monster? what'd you think when you saw that? >> well, that's when we were about to start jury selection. >> first day of jury selection. >> so, i think we were worried we were going to have another change of venue. >> but here it stayed. june 1st, 2004, a year and a half after laci peterson vanished, her husband, scott, went on trial for her murder. and right off the bat, the prosecution told the jury about scott and amber. he winced as they showed these photos of the two of them from the night of the party, the same photos that helped him get caught. and then they showed the jury this picture of laci, same night, different party. she went alone. >> the reason for the murder was he didn't want to be married anymore. he didn't want to have a child. he wanted a different life. and amber was just a symptom of that. he didn't want what he had. >> and he wanted to be rid of what he had. >> he did. >> one way or another. >> mm-hmm. >> laci and conner were responsibilities, and he didn't want that. >> he doesn't care about anyone but himself. he can be very smooth, but there's something underneath the surface that is truly evil. >> so, said the prosecutors, scott strangled or suffocated laci on christmas eve early in the morning, or possibly the night before. and then after that, after he had done that -- >> dragged her from the bedroom out to the carport. pickup truck backed into the carpo carport. take her out the side door, wrapped up, most likely, load her into the bed of the truck, drive over to the warehouse, move her to the boat, cover the boat. >> then, after sending an email and putting together a woodworking tool, law enforcement believed, he headed to the bay. but evidence of murder? that was all circumstantial. they had no incriminating dna, minimal forensics, just all those little strands. and in fact, it didn't always go well for the prosecution. as geragos worked to keep them off balance. >> we would try and present witnesses in a chronological order, in a way that made sense to our theory of the case, and they were very good at disrupting that and saying, we're not ready for that witness or -- >> just trying to throw a monkey wrench into your smooth telling of the story. >> yeah. >> if it happened once, maybe it was just coincidence. if it happened every single week, at some point in time, it's a plan. >> it got worse for the prosecution. geragos, who believed the modesto pd had it out for his client, tried to make it look like he had omitted evidence. he asked him on the stand, did you omit evidence about scott visiting the warehouse october 23rd? >> the answer was, "i did. " then, okay, we're done for the day. and it's like, you know, can i answer or -- >> and that was a very good point for him to make because it would create the impression that, in fact, laci did know about the boat, as scott said she did, and it lent credibility to the rest of the story as a result. >> well, maybe, maybe not. but he could have got the whole story. >> of course, the whole story wasn't what the defense attorney wanted, that the information was in another cop's report, that nothing had been hidden. but what did the jury think? what was your sense of how well that prosecution was going? >> i was a bit concerned. i felt that their burden of proving guilt beyond a reasonable doubt had not yet been met. >> but the big change, the c change, was the day she walked in. >> walking in the courtroom, you could hear body shifting towards the door. a lot of pressure. >> as scott watched, amber frey told the jury everything from strawberries and champagne on their first date to his tearful confession of losing his wife weeks before she went missing. >> how did you lose her then, before she was lost? explain that. >> there are different kinds of loss, amber. >> and all those phone calls were played for the jury. >> the jury could hear his words -- of course, not his words under oath, but his words on the phone call -- to amber and how he lied and lied and lied, and even lied about lying. >> mark geragos did what he could. he went after amber repeatedly, questioned her about how much she had to drink on her dates with scott and about how often she and scott had sex and how soon. did the defense rattle you? >> no. he tried. >> amber didn't buckle, and the prosecution hit its stride. an expert told the jury, the baby died between december 23rd and december 25th. another expert told the jury that laci's decomposition was consistent with three to six months in the water. and a search dog handler testified her dog picked up laci's scent at the berkeley marina. and, said the prosecutors, it was obvious scott peterson knew laci and conner were gone for good. he had even turned conner's nursery into a storage room. >> put office furniture and pillows and a locking device from a car in there. scott wasn't expecting conner to ever come home. >> coming up -- he's a lying cheat. >> yes, he was. >> a cheater, a liar, but a killer? i mean, really, who else could have done it. >> i'm glad you asked that question. >> when ""dateline"" continues. i lowered my a1c, cv risk, and lost some weight. in studies, the majority of people reached an a1c under 7 and maintained it. ozempic® lowers the risk of major cardiovascular events such as stroke, heart attack, or death in adults also with known heart disease. and you may lose weight. adults lost up to 14 pounds. ozempic® isn't for people with type 1 diabetes. don't share needles or pens, or reuse needles. don't take ozempic® if you or your family ever had medullary thyroid cancer, or have multiple endocrine neoplasia syndrome type 2, or if allergic to it. stop ozempic® and get medical help right away if you get a lump or swelling in your neck, severe stomach pain, or an allergic reaction. serious side effects may include pancreatitis. gallbladder problems may occur. tell your provider about vision problems or changes. taking ozempic® with a sulfonylurea or insulin may increase low blood sugar risk. side effects like nausea, vomiting, and diarrhea may lead to dehydration, which may worsen kidney problems. join the millions already taking ozempic®. ask your health care provider about the ozempic® tri-zone.

" >> scott had had that line used on him by a woman who was married. and he asked her if she was married and she said, i lost my husband. and scott decided that he liked that and that was a really good line. >> in other words, scott was a cad, not a killer, so said cole, anyway. but then how to explain the strange similarities between scott's fishing story and the circumstances of the murder? but you know, he went fishing in the bay. >> yep. >> they found the bodies in the bay. >> yes. >> i mean, really. who else could have done it? >> i'm glad you asked that question. let's remember the scene. she disappears. within a few days, scott's, "i went fishing in berkeley" story is all over the media. >> so, the real bad guys, maybe local sex offenders, or the two men arrested for the burglary across the street, took their victim to the bay and framed scott that way. that's cole's theory, anyway. it made more sense, he said, than the case against scott. so, what really happened on that cold december morning? 12 people would decide. >> members of the jury, you have heard all the evidence and the arguments of the attorneys. and now it is my duty to instruct you on the law that applies to this case. >> after five months of trial, the jury went off to deliberate. one day, two, a week they stayed out. and nobody knew, what were they thinking? coming up -- when dateline continues. when dateline continues. nearly two years after laci nearly two years after laci disappeared, disappeared, after nine days of deliberation, the jury in the scott peterson trial finally announced they had a verdict. >> it's pretty exciting and terrifying. >> as the crowds gathered out front, the reporters got into position, and everyone flooded back into the courtroom. what is it like for your level of anxiety? >> i felt like i was going to explode. >> the verdict is being read right now in a california courtroom in the double murder case against scott peterson. there is no camera in the courtroom, but an audio, live audio feed, is being provided. >> we, the jury, in the above-entitled cause, find the defendant, scott lee peterson, guilty of the crime of murder of laci denise peterson. >> finally, the words sharon and all those who loved laci had been waiting for -- guilty of laci's murder, and -- >> guilty of the crime of murder of baby conner peterson. [cheers and applause] >> outside the courthouse, crowds cheered. inside? >> i remember i just burst into tears. everything just comes gushing out. it's just two years of anxiety, of waiting. >> a month later, the jury decided scott's fate. >> we, the jury, in the above-entitled cause, affix the penalty at death. >> for 15 years, scott peterson sat on san quentin's death row, a condemned man. until 2021 something completely unexpected happened. the california supreme court affirmed one of his appeals and changed his sentence to life. and then, the justices took another step, they ordered the original court to evaluate another peterson's claims that one of the trial jurors, a woman named rachel nice known as strawberry shortcake, for her hair, lied to get on the case because she had it out first got peterson. the constitution guarantees the right to an impartial jury. so if peterson could prove nice was biased before she sat on the jury, scott peterson's conviction for killing his wife and unborn child would be overturned. and so, there were hearings through 2022, nice was questioned about her response on a questionnaire given now to potential jurors. and in particular, why she neglected to mention the incident of domestic abuse. she also failed to mention she had filed for a restraining order against a woman she said threatened her while she was pregnant. nice testified she hadn't remembered the restraining order and that's for the abuse, she was the one who started the fight, in fact. her boyfriend back then never hit her. even though he pleaded no contest to one charge of battery. peterson's appeals attorney told the judge, the original defense would have booted nice in the jury pool if he had known her true story. >> had he known about it he would've never permitted the jury. >> the prosecution counted that nice wasn't biased, she was just sloppy. >> being wrong does not necessarily make her false or a liar, might just be that she is really baddeck filling out a form. >> then, just before christmas 2022, the judge issued her decision. peterson's request for a new trial was denied. she wrote, nice's responses were not motivated by pre-existing or improper biased against petitioner, but instead were the result of a combination of good faith misunderstanding of the questions and sloppiness in answering. in april 2023 scott peterson filed a new appeal, so it is not over. and really, it won't ever be over for those who were drawn into this case. lacey's mother, her friends, their lives never really returned to normal. how could they? but they've adapted, like humans do. stacie, laurie and rene now have their own children, and those children who never met laci know her, in a way. >> she's part of our life. i mean, she is a part of our life still, so that means our children need to know about that part of our lives. >> she's special and she had a baby. >> so, the cemetery isn't a place of sadness for them, usually. >> i love it, because my boys get to hear about her and they always bring cars out for conner, or i think they brought a baseball out this time. >> it's a place where they can celebrate a life, someone they loved. >> she's in heaven and she's in our hearts. >> their laci. >> beautiful. >> oh, how pretty. >> i see her laying there on the floor. and i see a person i've never seen before in my house. and i'm looking at him and he tells me i'm next while he's reaching for a butcher knife. terrified. >> i just walked in and i saw blood everywhere. >> her daughter's laying there. a young girl coming home from lunch getting brutally attacked. >> blood on the floor. a shovel. duct tape. a knife. >> i rushed home. i truly thought brittani would die. >> somehow she battled back. a fight to live. >> it was a struggle. it was a
