Teenage Lifeguard

Magdalen Bish dropped her daughter Molly off at work on June 27, 2000, and never saw her again. The 16-year-old had trained as a lifeguard all winter and had been on duty at Comins Pond in Warren, Mass., for just eight days.

Her mother later recalled seeing a suspicious man sitting at the pond in a white car, but no one has ever been charged with the crime.
