Harry Edward Gibson Jr., 31, was last seen leaving his Phoenix home on the evening of April 23, 1984. He lived near North 79th Avenue and West Clayton Road and walked out of his residence at about 8:30 p.m., wearing a tan zip-up jogging jacket, blue jeans, and tennis shoes. Gibson is described as a white male with blond hair and blue eyes, about 5 feet 6 inches and 160 pounds.

Investigators have classified his case as endangered missing and say foul play is suspected, but few details or leads have emerged and the investigation has stalled. The Phoenix Police Department is the investigating agency. The disappearance remains unresolved and the circumstances of his vanishing are unknown.

Did anyone in the Phoenix area remember seeing Harry or his clothing that night, or have information that could help investigators?
