Overview of Steven Anderson

Steven Anderson was 17 years old when he and his roommate, David Williams, vanished from the New Libson State School campus in New Jersey. At the time, the New Libson State School was a state-run facility for students and adults with disabilities who required full-time care and services.

The day they went missing

The boys were last spotted on campus around 4:15 pm on April 7, 1975. Both Steven and David were heading to the baseball field located near campus. It is believed that both boys wandered off into the woods. However, by 8 pm that evening, David and Steven were reported missing. The school was right off Route 72. David was last seen wearing a blue jacket, striped pants, and a dark polo shirt. While Steven was last seen wearing a blue hooded jacket, blue shirt and trousers.

Another similar story broke 7 years after David and Steven went missing, Kenneth Schweighart, who was older at age 46, also vanished. He attended the same school as David and Steven and has not been found. The most recent action was the FBI searching a Wildlife Rescue where skull remains were found, but no further comments have come out of it.

If you have any information regarding Steven's case, please contact the FBI.
