The judge’s ruling is a seismic shift in a case that has haunted the American psyche for over two decades. Scott Peterson, the man convicted of murdering his pregnant wife Laci and their unborn son Conner, has just been granted a significant legal victory. A San Mateo County Superior Court judge has authorized his legal team to conduct extensive new DNA testing on key pieces of evidence, including a piece of duct tape found on Laci’s remains and items from a burned-out van near the Peterson home the day after she vanished.
Peterson, now 51 and serving a life sentence without parole, is doubling down on a theory that has long been dismissed by prosecutors. He claims that a burglary across the street from his home on the day Laci disappeared is the real key to her murder. In a stunning new interview from prison, part of the Peacock documentary “Face to Face with Scott Peterson,” he offered an explanation for one of the most damning pieces of his own behavior: why he kept in contact with his mistress, Amber Frey, after Laci went missing.
“I was searching for my family. I wanted the search to continue. Stay in contact with Amber, I thought, and she would get into the picture and help ruin the search,” Peterson told the documentary crew.
That statement, coupled with his legal team’s success in persuading Judge Anne-Christine Massullo to allow the new testing, has reignited a firestorm of controversy. The judge’s order, issued late Thursday, permits the Los Angeles Innocence Project, which took on Peterson’s case in early 2024, to access the full criminal lab file and perform advanced DNA analysis on evidence that defense attorneys argue was never properly examined during the original trial. “This is a huge win for Peterson,” said Susan Hendricks, an investigative journalist and author.
“The judge is allowing them to go back into all the state’s files, to see every person the state investigated. They will take even cleared suspects and turn them into the chief suspects.”
The ruling centers on a specific piece of duct tape found on Laci Peterson’s clothing after her body washed ashore in San Francisco Bay in April 2003, some four months after she vanished. Peterson’s legal team also won the right to test a blood-stained mattress from the burned-out van, which they believe could contain DNA from an unknown assailant. “The judge said that based on the cross-referencing of the investigation of the two cases, the orange van was part of the investigation of the offenses charged,” Hendricks explained.
“So the judge is allowing all of that evidence. The more she allows, the more holes can be poked in the prosecution’s case.”
Former Modesto Police Detective John Buer, who was deeply involved in the original investigation, reacted to the news with a calm that belied the gravity of the moment. “I can believe it because there’s only so much to do when you’re locked up in state prison. You’re doing everything you can to get out,” Buer said.
“I don’t see it as a real big deal for us. They can test all the evidence they want. I’m confident we got the right guy.”
Buer, who drove Peterson from San Diego to Modesto after his arrest, recalled a chilling moment that he says cemented his belief in Peterson’s guilt. “When we told him the DNA results had confirmed that the remains found were Laci and Conner, he didn’t react like a grieving husband. He ordered a double-double with cheese, a small fry, and a vanilla shake from In-N-Out 10 minutes later.
Who orders dinner right after finding out their loved ones are dead?”
Peterson’s new theory, that Laci was killed by burglars after she went to investigate a break-in across the street, has been met with fierce skepticism. “This woman could hardly walk at her Christmas party the week before,” Nancy Grace noted during the broadcast. “She had to sit down and put her feet up.
And I am supposed to believe that this woman, who couldn’t stand up at a party, went across the street to confront a group of male burglars while putting her first child in jeopardy?” Troy Slayton, a defense attorney, argued that Peterson’s past lies do not automatically make him a murderer. “Just because someone is a liar doesn’t mean they’re also a murderer,” Slayton said.
“There is no playbook for how to act when a family member is missing. Maybe he had already resigned himself to the fact that they weren’t coming back.”
Forensic experts, however, caution that the retesting may prove inconclusive. Toby Wilson, a forensic biologist, warned that the duct tape’s long submersion in San Francisco Bay could make DNA recovery nearly impossible. “The water will act as a dilution and washaway factor,” Wilson said.
“I would be very surprised if they get a usable DNA profile. The true value of the duct tape may be in fracture matches to a roll from Peterson’s warehouse or in fingerprints.” Dr.
Kendall Crowns, a medical examiner, explained the strict protocols used to preserve such evidence. “The body is wrapped in a sterile trace blanket at the scene, then placed in a sealed body bag. At the morgue, we carefully unwrap it and collect trace evidence under sterile conditions.”
The judge’s decision also allows Peterson’s team to review all bench notes, diagrams, and DNA reports from the crime lab. “They are going to see all the different people the state investigated,” Hendricks said. “They’ll look for someone who is already dead, because they won’t be here to defend themselves.”
Detective Buer remains steadfast. “If Peterson’s fingerprint is on the adhesive side of that duct tape, it will cinch the case. If the tape matches debris from some shrimp boat fisherman, it will show it was just litter that washed up with Laci.
Either way, the truth will come out.”
For now, Peterson remains behind bars, but his legal team is already preparing to use the new evidence to argue for a new trial. The sealed results of the duct tape testing were filed with the court in August, and the defense is expected to move quickly to have them unsealed and used as a springboard for further litigation. “This allows his team to poke holes and poke holes,” Hendricks said.
“They are going after the detectives, going after the police department. It is a big win for his side.”
The crime scene that once captured the nation’s attention is now being reexamined under a microscope of modern forensic science. Peterson’s claim that he kept his mistress to help find Laci has been met with widespread ridicule. “He is doubling down, hunkering down with the burglary theory,” Grace said.
“He knew they weren’t coming back. He ordered the 𝒑𝒐𝒓𝒏 channel, tried to sell her car, and used the baby’s room as storage before the bodies were even found.” Detective Buer recalled the moment he saw that room.
“When we went back on the second search warrant, we found a high-backed office chair and other items tossed into the nursery. It told the story that he knew they weren’t coming back.”
As the legal clock ticks, the nation watches to see whether Scott Peterson will succeed in his quest for freedom. The judge’s ruling does not grant him a new trial, but it opens a door that many thought was permanently sealed. For the family of Laci and Conner Peterson, the fight for justice continues.
For Scott Peterson, the double-double with cheese, small fry, and vanilla shake order remains a haunting symbol of a man who, according to those who investigated him, never showed a moment of genuine grief.
In the end, as Detective Buer said, the testing may prove nothing new. “I am confident we got the right guy. There is so much circumstantial evidence you cannot ignore,” he said.
But the process will be watched closely, as the Los Angeles Innocence Project, which has a track record of overturning wrongful convictions, brings its resources and reputation to bear on one of the most notorious cases in American history. For now, Scott Peterson has his biggest win since his 2004 conviction. What he does with it remains to be seen.
