Authorities say 12-year-old David Williams of Newark and 17-year-old Steven Anderson of Westville were roommates at what today is the New Lisbon Developmental Center. They had developmental disabilities and were unable to care for themselves without supervision.
They were last seen on April 7, 1975. An extensive search of the New Jersey Pinelands turned up nothing.
Williams would be 55 years old and Anderson would be 60 these days.
The FBI released age progressed photos of the two:
