The L.A.-based Innocence Project has taken on the case of Scott Peterson, who was convicted in 2004 of murdering his pregnant wife Lacey Peterson and their unborn child.

Peterson, now 51, is serving a life sentence for the murders. Lacey was 27 at the time of her death.

The Innocence Project said it will explore new evidence that has come to light in the case that may exonerate Peterson.

“The Los Angeles Innocence Project (LAIP) represents Scott Peterson and is investigating his claim of actual innocence,” a spokesperson told ABC News.

New evidence

Filings in the case also said, “New evidence now supports Mr. Peterson’s longstanding claim of innocence and raises many questions into who abducted and killed Laci and Conner Peterson.”

According to the filings, Lacey Peterson may have been a witness to break-ins across from their home. They are also testing DNA from a bloody mattress found in a van near their home after she went missing.

Her body was found in the San Francisco Bay four months later, and their son's body shortly thereafter a mile away from hers.

Peterson became a suspect in the murders when police discovered he was having an extramarital affair.

Death sentence reversed

He spent 15 years on Death Row after his conviction, but in 2020 the death sentence was overturned due to jury selection errors by the trial judge.

Scott's family has always been convinced of his innocence. They have argued that there was no physical evidence or timeline for the crime.

Scott’s defense attorney Pat Harris said of the news, “We are very excited to have the incredible attorneys at the L.A. Innocence Project lend their considerable expertise to helping prove Scott Peter’s Innocence.”

Just because LAIP takes the case doesn't mean Peterson will have his conviction reversed, but it does mean that questions still remain about what happened all those years ago and who was responsible.

The case got a lot of media attention and spawned several streaming TV shows, including The Murder of Lacey Peterson and Scott Peterson: An American Murder Mystery, both in 2017.

The case was also featured repeatedly on NBC's Dateline, Inside Edition, and other similar shows.
