Thomas John Lytle was 30 when he went missing from Kentfield, California, on June 1, 1986. He was living at the Buckelew House, a residential treatment facility that was not secured, and left the facility that day and never returned.

Lytle is described as a Caucasian man, 6 feet 2 inches tall, about 170 pounds, with brown hair, green eyes and moles on his face. He reportedly had a friend in Mendocino County but no means of transportation, a detail that complicates the disappearance. Family and counselors reported him missing after he failed to return, and the Marin County Sheriff’s Office classifies him as an endangered missing person.

No evidence has surfaced about his whereabouts and the investigation remains open. If anyone knew Thomas, saw him around June 1, 1986, or has information that could help, please contact the Marin County Sheriff’s Office.
