The search was exhaustive. Helicopters flew back and forth in the sky, searching the neighborhood for clues, while Green Berets and National Guard troops worked their way through the area.

On Saturday, August 21, 1976, a 10-year-old boy, Andy Puglisi, vanished from a public swimming pool near his home in the city of Lawrence, Massachusetts. His disappearance prompted an extraordinary search operation. In fact, more than 2,000 volunteers joined in. Despite their best efforts, though, Puglisi was never found.
