Warren M. Dean, 56, was reported missing after being last seen on May 30, 1990. He left his North Tonawanda home that morning at about 10:30 a.m.; his last known location was the Prospect Point overlook at Niagara Falls. At the time he was believed to be despondent, a detail that has been central to the concern around his disappearance.

Dean is described as a Caucasian male, 5 feet 10 inches, about 185 pounds, medium build, light complexion, grey or white hair and blue eyes. He was reportedly wearing a beige coat and has a vasectomy scar. The Niagara Regional Police Service has maintained a case file since 1990, but no definitive public explanation has emerged for what happened after he arrived at the heavily trafficked overlook.

If anyone remembers seeing Warren near Prospect Point on May 30, 1990, or has information about his movements that day, please share what is known.
