John Chocha, Jr. was 52 and a patient at Harrisburg State Mental Hospital in Harrisburg, Pennsylvania, when he vanished in the summer of 1969. Diagnosed with paranoid schizophrenia, he had privileges that allowed him to leave hospital grounds and visit town. He was about six feet tall with graying hair and blue eyes. A sister visited him in May or June 1969; the exact date of his disappearance is unclear but is often cited as July 19, 1969.

The family did not learn he was missing until weeks after that visit, when his wife called to arrange a visit and was told he was gone. The hospital had not notified relatives, delaying the initial search. Pennsylvania State Police investigations produced no leads, there has been no activity on his Social Security number, and after seven years with no contact he was declared legally dead. His whereabouts remain unknown.

If anyone has memories of John, the hospital in 1969, or information that could shed light on his disappearance, please share it.
