Details of Disappearance

David was last seen in New Lisbon, New Jersey on April 7th 1975. He was in the company of his roommate, Steven Anderson. Both boys were students at the New Lisbon State School for mentally challenged males. The school was located just off Highway 72.

The two boys were last seen walking towards their home on campus at approximately 4:30 pm after they played on a nearby ball field with some of the staff members. The boys never arrived to their home and were never seen or heard from again.

Apparently the boys weren’t the only students at the school to disappear without a trace. 5 years after they disappeared in 1982, a man named Kenneth Schweighart vanished after he left campus. Investigators have found no proof that the cases are connected and all three are missing under unknown circumstances.

The New Lisbon State School is now coed and known as the New Lisbon Developmental Center. The two boys have never been found and the case remains unsolved.
