The girlfriend of a serial killer, who admitted to killing a 20-year-old woman, will be released Thursday after serving 8 of 20 years behind bars.
Rachel Cumberland is set for release from the Central Mississippi Correctional Facility on earned release supervision. She was convicted in July 2005 on manslaughter charges after she pleaded guilty to killing a 20-year-old woman she and her boyfriend, John Robert Williams, met at a casino.
Williams was sentenced in 2007 to life in prison for the murder of the woman, however, he's also admitted to killing more than 30 others.
Williams and Cumberland are both suspects in the murders of Jennifer Hyman of Oklahoma City, Samantha Patrick, of Yukon, and Casey Jo Pipestem who was last seen at an Oklahoma City truck stop in January 2004. They were charged with killing Hyman, but those charges have been dismissed because of lack of evidence.
Police believe the women that were killed were all prostitutes at truck stops in Oklahoma, Texas, Mississippi, Indiana, and other states.
