Plot Synopsis

With the aid of re-enactments, archival photos, and interviews with detectives, MY EVIL SISTER chronicles stories of sisters who have done the unthinkable: killing their sibling or joining together to kill someone else. Each 60-minute episode features two cases, including the murders of: Linda Marie Brown, who married David when she was barely legal and was the victim of a bizarre plot -- and love triangle -- involving her husband and her live-in sister Patti; Teresa Fowler Straight, who was out for a night on the town with her sister Betty Jo and their significant others when a sibling argument turned into disaster, with Betty Jo running over Teresa with her Dodge Caravan; Stevie Allman, who was killed by her sister Sarah in an identity-theft crime, with Stevie's remains being stored inside a charred freezer in a burned-out house the two women shared; 14-year old Christina Sneary, who was shot in the neck by her sister Elena after an argument over a cell phone; and many other victims of sisterly sibling rivalries.
