2. Sergeant Drew Peterson
Outfit: Bolingbrook, IL Police Department
Crime: Drew Peterson was a sergeant with the Bolingbrook, IL police when his fourth wife Stacy vanished into thin air. Peterson initially seemed to love the attention his wife's disappearance brought and interviews with him began to raise all kinds of suspicions with investigators and the public.
He retired from the force in December 2007, and has since enjoyed a good deal of leisure time answering questions about Stacy's whereabouts and just what the hell happened when his third wife, Kathleen Savio, died in March 2004. (Lifetime even made a ridiculous movie about him starring Rob Lowe as the mustachioed creep.) In September 2012, a jury convicted Peterson of killing Savio.
Stacy Peterson has never been found.
