Anthony Andrzejewski, 20, vanished from the Delaware State Hospital on August 13, 1973. A patient there for about two weeks, he had intellectual disability, severe epilepsy and brain damage and had been granted ground privileges to move freely around the hospital grounds. He disappeared that afternoon between lunch and his scheduled medication at 4 p.m., carrying no money or identification.

At the time he went missing he was wearing a white t-shirt with blue trim, brown pants and white sneakers. Staff described him as shy and timid and noted a slight limp. Extensive searches of the hospital and nearby areas turned up nothing, and authorities have long considered the possibility of foul play though no conclusive evidence has been released.

His disappearance remains unsolved; does anyone have memories of the hospital grounds in 1973 or information that could help explain what happened to Anthony?
