Disappeared (2010)

S4E1 Missing Valentine

Patricia Viola, 42, is enjoying her ideal life, complete with two lovely children and a solid, happy marriage. On February 13, 2001, she goes through her usual routine, preparing the kids for school and then volunteering at the local library. After a quick call to her mother, she mysteriously vanishes without a trace. Authorities quickly initiate an investigation to discover whether she was a victim of a crime or chose to disappear on her own. A decade later, a private investigator uncovers an unexpected link between Pat and a triple homicide that could change everything in the case.
