Summary based on 2 sources
On May 30, 1990, 56-year-old Warren M. Dean, a male resident of North Tonawanda, New York, was reported missing after he was last seen in Niagara Falls. That morning, at approximately 10:30 a.m., he departed from his home. His last known location was in the vicinity of Prospect Point, a well-known overlook offering dramatic views of the American Falls. At the time of his disappearance, it was believed that Mr. Dean was in a despondent state, a detail that has been a concerning factor in his case from the beginning.

Warren M. Dean is described as a Caucasian male, standing at 5 feet 10 inches tall and weighing around 185 pounds. He had a medium build, a light complexion, grey or white hair, and blue eyes. When he was last seen, he was reportedly wearing a beige coat. A vasectomy scar is also noted as a distinguishing physical characteristic. The Niagara Regional Police Service is the primary agency investigating his disappearance and they have maintained a case file on him since 1990.

Decades have passed since Warren M. Dean was last seen, and his case remains an unresolved missing person investigation. The initial report of his disappearance, coupled with the mention of his emotional state, has left his family and investigators with lingering questions and concerns. The area where he was last seen, Prospect Point, is a heavily trafficked tourist location, yet no definitive information has publicly surfaced to explain what happened to him after he arrived there. The overview of this case is one of a sudden and troubling disappearance, with the trail seemingly going cold at one of the world's most famous natural landmarks, leaving a void of answers for those who knew him.
