What Scott Peterson Believes Happened to Laci Peterson 20 Years After Murder Conviction

In maintaining his innocence, Scott Peterson has a theory about what really happened to his wife Laci Peterson.

In his first on-camera interview since he was convicted for her murder 20 years ago—and the murder of their unborn son Conner, with whom Laci was over eight months pregnant with at the time­—Scott provides a possible answer as to who could have been responsible for her death, if not him.

"There was a burglary across the street from our home," Scott said in Peacock’s new three-part series Face to Face With Scott Peterson. "And I believe that Laci went over there to see what was going on, and that's when she was taken."

While a burglary was in fact committed near the Peterson’s home around the time Laci went missing, authorities have countered these claims by citing one of the convicted burglar's statements that the break-in occurred on Dec. 26 rather than Dec. 24, 2002, as the defense has alleged.

However, as part of the series, journalists and legal experts note that there are witnesses who told police they saw a suspicious van in the vicinity of the burgled home on Dec. 24, while one witness goes so far as to claim they saw a pregnant woman being forced into a van.

Yet the burglary was not brought up during Scott’s trial, which he cites in the documentary as supporting his claim that the cops didn't turn over evidence to the defense that could have potentially exonerated him during the discovery process as they were supposed to.

As Scott alleged, “There are so many instances where there was evidence that didn't fit the detectives' theory that they ignored.”

It’s an allegation Modesto Police are quick to discredit. In the series, two former detectives for the department Jon Buehler and Al Brocchini affirm they never hid evidence or failed to investigate leads during the investigation, and that nothing they’ve heard in the 20 years since Scott’s conviction have swayed their opinion on his culpability.

Yet while Scott was ultimately convicted of Laci and Conner’s murders, there are many—including his sister-in-law Janey Peterson—who maintain his innocence. In fact, the Los Angeles Innocence Project took on his case earlier this year, filing a motion to have pieces of evidence from the original investigation tested for DNA.

It is only one of the many noteworthy details examined in the three-part series. For more on the many unsettling moments in Face to Face with Scott Peterson, keep reading.
