33 - 12: The Hunt for the Long Island Serial Killer

Megan Waterman was one of the first victims of the Long Island serial killer found by police. In December of 2010, four women - aged 22 to 27, similar in height, weight, hair and eye color - were found dead along a stretch of Ocean Parkway near Gilgo Beach on Long Island, N.Y. They became known as the "Gilgo Four." Now, a decade after Megan Waterman's body was found, her teenage daughter talks for the first time on television with 48 HOURS correspondent Erin Moriarty.
