Scott Peterson's longtime lawyer claims 'new' evidence could force courts to revisit his murder conviction

Geragos said a burned-out van found near the Petersons' house after a burglary could be connected to the case, and alleged that prosecutors initially hid that piece of evidence.

"There was a van, it was ditched and set on fire very close to the house, within miles," Gergaos said. "That van contained a treasure trove of evidence that should have been tested in real time, some of which was, some of which still exists, and that they're actively not trying to or prevent the defense from doing it."

Geragos says the Los Angeles Innocence Project gave the court a "laundry list" of items that could be retested for DNA, which was rejected.

"Why wouldn't you want to? Why wouldn't you want vindicate yourself if you're the prosecution? The only explanation is because you're not sure that you've got the right guy," Geragos said.

"So I think there are two real critical areas where exculpatory information was not provided to the defense team," Toosbuy said. "One was the multiple witnesses who had contacted Modesto PD to say that they had seen Laci Peterson on the morning of the 24th. Those witnesses were not all vetted out."

"If just one or two witnesses had been vetted and could have confirmed that, in fact, they did see Laci Peterson in the park or in the neighborhood, and that their statement was reliable, that would have immediately, within the first 48 hours, eliminated Scott Peterson as a suspect. And yet that was an area that Modesto PD decided not to pursue. And from my standpoint as an investigator, it's a real failure of the investigation," she added.
