On the 10-year anniversary of the discovery of the first victims of the Long Island serial killer, “48 Hours” goes inside New York’s biggest unsolved murder case.
Lily Waterman, 14, was just 3 years old when her mother Megan Waterman disappeared. Megan was one of four women whose remains were found discarded near Gilgo Beach on Long Island in December 2010.
Lily tells her story on television for the first time.
