Daniel H. Deaner was 49 when he disappeared from Central Islip, New York, on May 18, 1981. He had been released from Central Islip Hospital that day and was never seen or heard from again. At the time he was described as a Caucasian male, 5 feet 4 inches tall, about 170 pounds, with brown hair, blue eyes and a scar on his upper lip.

Why Daniel was at the hospital or the circumstances of his release are not publicly detailed, and there is little available about his life, relationships or state of mind before he vanished. The Suffolk County Police Department handled the investigation; the case grew cold due to a lack of witnesses, forensic evidence and significant leads. The case remains open.

If anyone knew Daniel, his routines in Central Islip, or remembers seeing him after May 18, 1981, please share what you know with the Suffolk County Police Department.
