Nearly two decades after the death of Laci Peterson, husband Scott Peterson‘s death sentence for the first-degree murder in her death and second-degree murder in the death of their unborn son was reversed by a California judge. Though his conviction for the murder was upheld, the California Supreme Court determined on Monday, August 24, there were “a series of clear and significant errors” during the trial’s juror selection.

Laci, 27 years old and 8 months pregnant at the time of her disappearance, was the subject of national news for the months she was missing (and for a while afterward). Here are the events of that excruciating period of uncertainty.

December 23, 2002: Laci’s half-sister, Amy Rocha, and Laci’s mother, Sharon, are the last two people — aside from Scott — to speak to her.

December 24, 2002: Scott Peterson calls the police to report Laci missing from their home in Modesto, California. He claims that he last saw her mopping the floor and planning to walk their dog when he left for a fishing trip to Berkeley Marina — and that she was nowhere to be found when he returned.
