Dennis Patrick Harrington was 33 when he vanished from Monte Rio, California, on July 28, 1995. He was last seen in the small Sonoma County town wearing a black hooded sweatshirt and black Ben Davis pants. He is described as 5 feet 11 inches tall, about 160 pounds, with brown hair and hazel eyes.

Dental records are on file, but records do not note other personal items or distinctive marks. The investigation produced few leads, and the case remains open and unsolved with no confirmed sightings or information about his whereabouts since that July day in 1995.

Does anyone who lived in Monte Rio in 1995 remember Dennis or have information that could help locate him?
