Dennis Dewitt Davidson was 27 when he was last seen in Flint, Michigan, on July 9, 1981. He was described as a white male with brown hair and brown eyes, about 6 feet 1 inch tall and roughly 130 pounds. No photograph, clothing description, last known address, or final sighting details are publicly recorded.

Investigators eventually came to believe Dennis was the victim of a homicide, but his remains have never been recovered and no crime scene or cause of death has been disclosed. The case is listed with the Genesee County Sheriff’s Office as case number 81-2732 and appears in the National Missing and Unidentified Persons System; a family DNA reference sample is noted as pending.

Many basic facts about his last day remain unknown, including who last saw him, where he lived, and what he was doing before he vanished. Does anyone have memories or information about Dennis, his movements in July 1981, or family members who could help investigators?
