Scott Peterson & Laci Peterson: The Husband Who Murdered His Pregnant Wife for a Fresh Start
He didn't want a divorce — he wanted his pregnant wife to disappear
Key Facts
What Happened
Scott and Laci Peterson appeared to be the perfect couple in Modesto, California. They married in 1997, bought a home, and were expecting their first child — a boy they planned to name Conner. But in November 2002, Scott began a secret affair with Amber Frey, a Fresno massage therapist, telling her he was single. On Christmas Eve 2002, Laci Peterson — 27 years old and eight months pregnant — disappeared. Scott told police he had been fishing alone in the San Francisco Bay that morning.
Scott's behavior immediately raised suspicion. He sold Laci's car, researched tidal currents in the Bay, purchased a boat weeks before the disappearance without telling anyone, and was caught lying to police repeatedly. In a pivotal moment, Amber Frey — who had learned Scott was married from a news report — went to police and agreed to record their phone conversations. On tape, Scott told Amber he had 'lost his wife' and would be spending his 'first Christmas alone' — while the entire nation was searching for Laci.
On April 13, 2003, the remains of an infant boy washed ashore in the San Francisco Bay. The next day, Laci's torso was found nearby. DNA confirmed their identities. Scott was arrested on April 18, 2003, near the Mexico border with $15,000 in cash, his brother's ID, and newly dyed blond hair. On November 12, 2004, after a five-month trial, the jury convicted him of first-degree murder for Laci's death and second-degree murder for Conner's.
Scott was originally sentenced to death on March 16, 2005. In 2020, his death sentence was overturned on appeal due to juror misconduct, and he was resentenced to life in prison without the possibility of parole. He has continued to pursue appeals, claiming new evidence. The case remains one of the most horrifying examples of what can happen when someone decides they want 'out' of a marriage but chooses murder over divorce. Laci's mother, Sharon Rocha, became an advocate for victims' rights, and the federal 'Unborn Victims of Violence Act' (Laci and Conner's Law) was signed in 2004.
Legal Breakdown: When Divorce Turns Deadly
When Someone Chooses Murder Over Divorce
Scott Peterson could have filed for divorce. California is a no-fault state — he did not even need grounds. Instead, he chose to kill his pregnant wife and unborn son. Research shows that family annihilation cases often involve men who perceive divorce as too costly, too embarrassing, or too inconvenient. The warning signs include secretive behavior, new relationships while married, financial preparations for a 'new life,' and emotional detachment from family obligations. If your spouse is exhibiting these patterns, take them seriously.
The Danger of the 'Perfect Husband' Facade
Scott Peterson presented himself as a devoted husband while secretly maintaining a double life. Neighbors, friends, and family were shocked. This case illustrates that danger can hide behind a charming exterior. Trust your instincts — if something feels 'off' about your spouse's behavior (unexplained absences, secretive phone use, sudden financial changes), investigate or consult a professional before confronting them.
Amber Frey's Courage Changed the Case
When Amber Frey learned the truth about Scott, she immediately went to police and agreed to wear a wire. Her recorded conversations became the prosecution's most powerful evidence. This case shows the importance of cooperating with law enforcement when you discover you are entangled in someone else's crime. If you discover your partner is hiding something dangerous, contact authorities — you could save a life, including your own.
What This Means for Your Divorce
- →If your spouse begins behaving secretively — new phone habits, unexplained purchases, emotional withdrawal — these can be warning signs of a double life. Trust your instincts.
- →Pregnancy is a statistically dangerous time in abusive relationships. Homicide is a leading cause of death for pregnant women in the United States. Safety planning is critical.
- →Divorce is always an option. No-fault divorce exists in every US state. No situation is so trapped that violence is the only way out.
- →If you feel unsafe at any point during a marriage or divorce, tell someone you trust and contact the National Domestic Violence Hotline: 1-800-799-7233.
