Stacy Peterson was—at the oldest—17 and working the overnight shift at a Bolingbrook motel when she met and became romantically involved with Drew Peterson. This affair prompted Drew Peterson's divorce from third wife Kathleen Savio. Drew Peterson bought a house down the street from the home he lived with Savio and he and Stacy moved in together. The close proximity and tension between Drew Peterson and Savio allegedly erupted into violent epidsodes involving the divorcing couple and the new young lover. Stacy vanished in October 2007. Drew Peterson claims she ran off with another man. The Illinois State Police believe Drew Peterson may have something to do with possibly killing her. Stacy's disappearance prompted the state police to exhume Savio's body and eventually charge Drew Peterson with murdering her.
