Summary based on the NamUs case record (MP73876) and 7 other sources
Anthony Andrzejewski, a 20-year-old man from New Castle, Delaware, disappeared on August 13, 1973, from the Delaware State Hospital. Anthony, who was intellectually disabled and suffered from severe epilepsy and brain damage, had been a patient at the hospital for two weeks before his disappearance. He had been given ground privileges and was allowed to move around freely on the hospital grounds. However, despite never wandering off before, he vanished that afternoon between lunch and his scheduled medication at 4 p.m. He did not have any money or identification with him.

At the time of his disappearance, Anthony was wearing a white t-shirt with blue trim, brown pants, and white sneakers. He was described as being shy and timid, with a slight limp. Despite extensive searches of the hospital and surrounding areas, no trace of him was ever found. His disappearance has remained unsolved for decades, and authorities believe he may have met with foul play, though no conclusive evidence has emerged to explain what happened to him.

The mystery surrounding Anthony’s case has left his family and investigators without answers for over 50 years. Efforts to uncover new information about his whereabouts continue, with hopes that renewed attention might lead to a breakthrough.
