Key Facts: Laci Peterson Search, Discovery, and Official Conclusions
Laci Peterson was reported missing on December 24, 2002, in Modesto, California. On April 13, 2003, her body was recovered in the shallow waters of the San Francisco Bay shoreline near Antioch. Her fetus, Connor, was also recovered. The search involved local, state, and federal teams using sonar, dive teams, and cadaver dogs. No body had been found before April 2003; the discovery occurred more than three months after she vanished. Investigators linked the remains and fetal tissue to Laci and the pregnancy timeline.
Details of the Search and Recovery
Initial Searches and Resources Deployed
In the weeks after Laci’s disappearance, volunteer groups, law enforcement, and air support conducted extensive ground and aerial searches across waterways, rural areas, and open terrain around Modesto and the San Francisco Bay Delta. Resources included helicopters, sonar-equipped boats, and dive teams. These efforts yielded no recoverable remains. The search expanded as investigators refined information about her likely movements and last confirmed sightings.
Discovery of Remains and Evidence Recovered
On April 13, 2003, a recreational boater discovered a skull and partial skeletal remains on the shoreline in an Antioch area known as Rocky Point. Subsequent dive operations recovered additional bones and fetal tissue. Medical examiners determined the remains were consistent with a late-stage pregnancy and matched Laci’s dental records. Fetal remains were identified as consistent with a full-term pregnancy.

Official Investigations and Findings
Search and Dive Operations
From late December 2002 through April 2003, multiple agencies coordinated dive operations in the San Francisco Bay and nearby rivers. Dive teams searched channels, levees, and low-lying shoreline areas where remains could have moved or settled. Sonar and side-scan technology were used to identify anomalies that warranted closer examination. Despite extensive coverage, no recoverable remains were found before April 2003.
Medical Examiner and Forensic Analysis
The remains were transported to a county medical examiner for identification and autopsy. Examiners estimated the remains were from a woman in the third trimester of pregnancy. Fetal tissue found at the scene matched both the expected gestational age and Laci’s prenatal records. The condition of the remains was consistent with a body exposed to water for several months before recovery. The fetus’s remains indicated the full-term baby had been delivered around the time of Laci’s death.
What Was the Outcome of the Investigation?
The recovery of Laci’s body provided physical evidence that supported the timeline presented by investigators. The presence of fetal remains enabled forensic confirmation of the child’s identity and developmental stage. The findings aligned with law enforcement’s theory of a homicide occurring close to the time Laci was last seen. In 2005, a jury convicted Scott Peterson of murdering Laci and their unborn son. No remains believed to be Laci or Connor have been found outside the forensic conclusions reached in 2003.
