Stacy Peterson, 23, disappeared on October 28, 2007 after failing to show up at her sister’s home to help her paint. Drew Peterson said he’d spoken with her that night, claiming she’d told him she was leaving him for another man. 

Stacy told friends and family she was afraid Drew would kill her. 

Peterson was ultimately convicted of the murder of his third wife, Kathleen. His 4th wife Stacy is still missing and presumed dead.
