Early news footage
On the morning of Sep.18, 1998, a 17-year-old named Aimee walked into the Bismarck Police Department and stated she thought her boyfriend had hurt his parents. Within an hour investigators discovered a bloody crime scene and yet no victims. Barbara and Gordon Erickstad's bodies were located 40 miles south of Bismarck later that evening.
Before the victims were located, investigators named Robert Lawrence and Brian Erickstad as prime suspects.
