Forensic Files - Season 5 - Eps 19: Deadly Knowledge
When 23-year-old college co-ed Tina Biggar goes missing, her boyfriend and family fear she has been murdered. A police investigation reveals details about her past that no one, not even her closest friends, suspected: She was a student by day and a $100-an-hour call-girl by night. Her many clients were all suspects in her disappearance, as was her boyfriend. But when her body is discovered, investigators gather evidence that implicates her killer.
