Missing Since: 1982-03-02 Location: None, New Jersey
Schweighart was a resident of the New Lisbon State School for Retarded Males in New Lisbon, New Jersey in 1982; he had lived there for approximately four years. His family lived in Garfield, New Jersey. He left the campus at 11:45 a.m. on March 2, 1982 and has never been heard from again. Curiously, Schweighart is not the only New Lisbon State School resident who went missing and was never heard from again; Steven Anderson and David Williams disappeared from there together in 1975. It hasn’t been proven that the disappearances are related. The New Lisbon State School is now coed and known as the New Lisbon Developmental Center. All three cases remains unsolved.
