Laci Peterson

2002 murder victim, subject of major criminal case

Biography

Laci Denise Rocha Peterson (May 4, 1975 – December 24, 2002) was a 27-year-old woman from Modesto, California, whose murder became one of the most sensational criminal cases in modern American history. While eight months pregnant, Laci disappeared on December 24, 2002, on Christmas Eve. Her body, along with that of her unborn son, was discovered in San Francisco Bay in April 2003. Her husband, Scott Peterson, was convicted of her murder in 2004 and sentenced to death, though his conviction has remained controversial due to legal procedural questions and debates about evidence. The case drew unprecedented media attention, becoming a cultural phenomenon and leading to extensive coverage of domestic violence issues. Laci's case was pivotal in raising awareness about crimes against pregnant women and spouses, influencing legislative changes including California's Laci and Conner's Law. Her disappearance and the subsequent trial dominated news cycles for over a year and remains a frequently studied case in criminology and media studies.
