John Benson, a 58-year-old retiree who lived alone in Manchester, Vermont, was found dead inside his home on November 14, 1983. The cause of death was multiple gunshot wounds, and the killing was ruled a homicide.

Investigators established that Benson had received visitors at his residence on the night he was killed; those visitors were reportedly people he knew, which suggested the attacker was not a forced intruder but someone familiar to the victim. Despite that lead, the investigation went cold. The case remains an open, unsolved homicide in the Vermont State Police files, with no arrests or publicly identified suspects.

Does anyone who knew John Benson, his visitors that night, or who lived in Manchester in 1983 have information that could help finally close this case?
