AI Summary

5 min read

On December 8, 2001, Kathleen Peterson and her husband Michael spent a rare, relaxed evening together—Christmas shopping, dinner, wine by the pool. Michael said he dozed off outside. When he woke, he went inside and found Kathleen sprawled at the foot of the stairs, bleeding, her eyes open and vacant. He called 911 and told the operator she had fallen. But by the time paramedics arrived, the Durham police already suspected something else. The scene was saturated with blood. The medical examiner would later count seven distinct lacerations on Kathleen’s head. The official cause of death was blunt force trauma, not a fall. Within two weeks, Michael Peterson was arrested and charged with first-degree murder.

Show Notes

When Kathleen Peterson died in December 2001, it was assumed her death had been the result of an accidental fall down the stairs after combining alcohol and Valium. However, within a few weeks, suspicion fell on Kathleen’s husband, Michael, after the medical examiner concluded that Kathleen’s injuries were consistent with assault, not an accidental fall.

By the time Michael Peterson went to trial, the case had attracted national attention, particularly after details about his personal life came to light. The case gained even more attention when it was learned that, in 1985, Michael Peterson’s friend Elizabeth Ratliff died under very similar circumstances to those of his wife.
