Background and Relationship Timeline

Meeting and Marriage

Scott and Laci Peterson met in 1995 and began dating years before marriage, sharing a lifestyle that appeared stable and middle-class to neighbors. Their relationship progressed to marriage in 2000, and Laci became pregnant in 2002, intensifying discussions about family plans and futures.

Pregnancy Expectations

The couple was preparing for the arrival of their first child, with Laczi due in May 2003. Friends and family noted excitement about the pregnancy, and Scott frequently spoke about becoming a father, making his eventual conviction for Laci's murder and their son's death especially shocking.
