Summary based on the NamUs case record (MP747) and 4 other sources
John Joseph Simons, aged 35, disappeared from his residence in Stony Brook, New York, on March 15, 1991. He was last seen at his home on Horton Boulevard, and no one has heard from him since. Simons suffered from depression and required medication, leading authorities to classify his case as one of endangered missing.

At the time of his disappearance, Simons was described as a 6-foot-tall Caucasian male weighing 150 pounds, with brown hair and brown eyes. He also wore wire-framed glasses. Few details have emerged about the circumstances of his disappearance, and there have been no significant leads in the case.

Despite ongoing investigations, including by the Suffolk County Police Department, Simons's fate remains unknown. His case is still listed in various missing persons databases, and his family continues to hope for answers.
