When 63-year-old Wisconsin wife and mom Victoria Prokopovitz went missing in 2013, her three grown children were beside themselves with worry. Her husband of 24 years, Jim, seemed oddly unconcerned, telling police she often wandered off and had tried to commit suicide twice. Despite a massive search, Victoria was never found. A private detective was brought in by her daughters; conducting his own investigation, he learned of a secret affair.
