Context: The Real Kathleen Peterson Case
The real case began when Kathleen Peterson was found dead at the bottom of a staircase in her Durham, North Carolina, home in December 2001. Michael Peterson, a novelist and former congressional aide, called 911 and claimed he found her there after a night out. Prosecutors argued that distinctive wounds on her head indicated a violent struggle and suggested Michael inflicted them during a domestic dispute. Defense experts proposed alternative explanations, including a possible fall. After a mistrial and a subsequent plea deal, Michael Peterson was sentenced to time served and released. The ongoing disputes over forensic science and timeline accuracy remain central to discussions about the case.
