SCOT PETERSON CASE: MURDER OF LACI PETERSON
Laci Peterson
On Christmas Eve, December 24, 2002, 27-year-old Laci Peterson, who was eight months pregnant, was reported missing by her husband, Scott Peterson, and her stepfather. Scott told authorities he had gone fishing that morning at the Berkeley Marina, nearly 90 miles from their home in Modesto, California, and that he last saw Laci before leaving. Laci’s mother later stated she had spoken with her daughter the night before. The report launched an extensive search for the missing expectant mother.

Scott Peterson Case Files: Timeline
Scott Peterson, born on October 24, 1972, was convicted in one of the most closely followed criminal cases of the early 2000s for the murders of his pregnant wife, Laci Peterson, and their unborn son, Conner. Laci vanished on December 24, 2002, from the couple’s home in Modesto, California, just weeks before her due date. Initially treated as a missing persons case, the investigation quickly turned toward Peterson, whose actions drew national attention.
In April 2003, the remains of Laci and Conner were discovered along the shoreline of San Francisco Bay, near the area where Peterson had claimed to be fishing the day she disappeared. Despite maintaining his innocence, Peterson was arrested, tried, and convicted in 2004. He was sentenced to death in 2005, though the sentence was later overturned. More than 20 years later, the case continues to generate legal challenges and widespread media interest.

March 18, 2025
- Scott Peterson Was involved in a fight in prison, sustained minor injuries
April 21, 2025 The Los Angeles Innocence Project Issued a Press Release claiming:
- Burglary Timeline Disputed: New evidence suggests the Medina home burglary happened on December 24, the same day Laci disappeared—not December 26 as police and prosecutors told the jury.
- Additional Burglary Involvement: Others besides the two convicted burglars may have been involved. A witness allegedly heard them discuss Laci confronting them.
- Three Nearby Crimes: The petition connects Laci’s disappearance, the Medina burglary, and an arson vehicle fire, all occurring within 24 hours and close to the Peterson home. Police failed to investigate them as related.
- Suppressed and Ignored Evidence: A van fire contained a mattress with suspected blood—police failed to test DNA properly and suppressed records. DNA was found but not subjected to advanced testing. Interviews with the burglars and physical evidence (including a safe) were destroyed soon after Peterson’s arraignment.
- Flawed Forensics: The prosecution’s fetal growth timeline was based on outdated science. New research shows Conner likely died after December 28—when Scott could not have been responsible. Their own expert admitted a newer fetal growth formula placed Conner’s death around January 2, 2003.
- Inaccurate Tidal Testimony: Expert hydrodynamic modeling shows the bodies could not have drifted from Scott’s fishing location to where they were found. The model points instead to dumping from the Albany Bulb, accessible by car.
- Ignored Eyewitness Accounts: 11 witnesses reported seeing Laci walking her dog after Scott left home, but police dismissed and never followed up.
- Boat Purchase Mischaracterized: Handwritten notes from Laci show she and Scott may have purchased the boat together, contradicting claims Scott bought it secretly to commit murder.
- Investigative Misconduct Alleged: A former LAPD lieutenant concluded the investigation was disorganized and biased, with critical evidence ignored or destroyed. Police allegedly gave false testimony about eyewitnesses and a watch tied to Laci that was later linked to one of the burglars.
Conclusion from LAIP: The petition argues that the prosecution’s entire theory has collapsed under new evidence and cumulative constitutional violations. The evidence supports a prima facie claim of innocence and demands a new trial.
