Prosecutors entered the letter Monday as they wound down their four-week presentation. Peterson has pleaded not guilty to murdering Kathleen Savio in 2004.
Savio wrote the letter to a prosecutor in 2002 amid the couple’s acrimonious divorce. It’s often rambling and angry as she describes an incident in which she says Peterson put a knife to her throat. Savio says in the letter that she thought she was about to die.
Savio’s body was found in her bathtub, and her death was initially ruled an accident. Her death was only ruled a homicide after Peterson’s fourth wife, Stacy Peterson, went missing in 2007.
