Two boys who disappeared from a state facility in New Jersey in 1975 have been added to the FBI's missing persons website.
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. They were last seen walking towards their residence from a nearby ball field where they had been playing with staff members.
An extensive search of the New Jersey Pinelands turned up nothing.
Williams would be 55 years old and Anderson would be 60 these days.
FBI Newark Special Agent in Charge Timothy Gallagher says no matter how long a child is missing, it will always be a top priority for the FBI.
According to the FBI, Anderson had a chipped front tooth, was known to have trouble communicating, and was last seen wearing a blue hooded jacket and blue pants. He was 5-feet-8 and 140 pounds when he disappeared.
Williams was an epileptic who needed to take daily medication, and generally wore a helmet to protect his head, the FBI said. Without the medication, he could have suffered a grand mal seizure. He was last seen wearing a blue jacket and striped pants.
