The new scientific evidence in the Scott Peterson case is so compelling that it is “ripe for a retrial,” according to an exclusive analysis by a former defense attorney and legal analyst who has spent six months re-examining the 2004 murder conviction. The Los Angeles Innocence Project has uncovered data that did not exist 24 years ago, including a Harvard radiologist’s conclusion that Conner Peterson, Laci’s unborn son, died sometime between December 28 and early January 2003, not on Christmas Eve when Laci vanished.
This timeline would fully exonerate Scott Peterson if Conner died four days after Laci went missing, shifting the window of her death and undermining the prosecution’s theory. The expert, who previously stood toe-to-toe with Nancy Grace on national television, said he was “floored” by the evidence. “The public is going to see a completely different story here,” he said.
“This investigation is leaving us with more questions than answers.”
The Los Angeles Innocence Project has spent years conducting a deep dive into the specifics of the evidence that led to Peterson’s conviction. Independent experts, including top professionals in their fields, have examined the findings. They argue that Peterson was wrongly convicted because the jury relied on false evidence, including false scientific testimony, violating his constitutional rights.
“If the information the jury receives is not reliable,” the analyst stressed, “then the verdict is not reliable.”
Two critical pieces of new evidence stand out. The first involves expert testimony at trial about where Laci Peterson’s body would have been placed in the San Francisco Bay. A prosecution expert claimed the body was dumped south of Brooks Island, exactly where Scott Peterson said he was fishing.
That testimony, the analyst now says, was based not on expertise but on a guess. “When an expert gets on the stand and says, ‘I’m a tide expert, and Laci’s body was placed here,’ that carries enormous weight,” he said. “But it was fundamentally unreliable.”
The second piece involves new science regarding the fetal age of Conner Peterson. The Innocence Project brought in a tenured Harvard radiologist whose conclusions contradict the trial timeline. If Conner died after December 28, Scott Peterson could not have killed Laci on Christmas Eve.
This technology simply did not exist in 2004 when Peterson went to trial. The analyst noted, “That would fully exonerate Scott Peterson.”
Eyewitness accounts also paint a troubling picture. More than a dozen witnesses reported sightings of Laci walking her dog within days of her disappearance. They described a pregnant woman with short dark hair struggling to control a golden retriever.
The Modesto police never followed up on these reports. “It is an enormous oversight to decide eyewitness statements are not worthy of our time because Scott Peterson is our guy,” the analyst said. “That seems to be what happened.”
The absence of forensic evidence is equally striking. There was no evidence in the Peterson home, no evidence in Scott’s truck, and no evidence in his boat. These were the three locations where prosecutors claimed the murder and body transport occurred.
“You should have some physical evidence here,” the analyst said. “The absence of it should be of great concern to the public and ultimately to the jury.”
Critics point to Scott Peterson’s behavior, including his demeanor after Laci’s disappearance, his 𝒶𝒻𝒻𝒶𝒾𝓇 with Amber Frey, and his arrest at a golf course with his brother’s ID, $15,000, camping gear, and a changed appearance. Some describe him as a sociopath, pathological liar, and manipulative. The analyst acknowledged this but said such evidence only shows a possible consciousness of guilt, not proof of murder.
“This type of evidence only shows a possible consciousness of guilt,” he said. “At the time and now, I never really had a problem understanding the change in appearance. If a reasonable 20-something person puts themselves in his shoes and looks at what the media was doing, it was reasonable to conclude you have absolutely no chance of a fair trial.”
He added, “He absolutely brought about his conviction. Every day he spends in prison, he has to acknowledge he’s there because he was 𝒸𝒽𝑒𝒶𝓉𝒾𝓃𝑔 on his wife. Had he not been 𝒸𝒽𝑒𝒶𝓉𝒾𝓃𝑔, I think the state’s case would have been looked at with a much more critical eye by the media, the public, and ultimately the jury.
I don’t think it would have been the same result.”
The investigation also uncovered a burglary directly across the street from the Peterson home on the day Laci vanished. The Modesto police initially changed the date of that burglary, according to the analyst. “They made a decision a few months after Laci’s disappearance to destroy all of the evidence with respect to that burglary,” he said.
“There are really major questions about what role the Medina burglary may have played in Laci’s disappearance.”
The Los Angeles Innocence Project has now taken up the case, and the analyst has spoken with Peterson’s family and legal team. “Do you know how he’s feeling?” the analyst was asked.
“My understanding is that he’s been hopeful,” he replied. “He’s not everybody’s favorite person, but it’s telling that the Los Angeles Innocence Project would put their reputation behind this.”
The analyst concluded with a call for justice. “Whether you believe Scott Peterson is guilty or innocent, all of us should care enough about our criminal justice system that when we see a case with so much false testimony and so much error, we should want that to be re-examined.” The Innocence Project now has 120 days to take the case to the California Supreme Court.
“The evidence here is so compelling that this case will receive review,” the analyst said. “It’s ripe for retrial. This is far from over.”
