Joseph Caponetti, 57, was last seen the morning of April 10, 1979, when he left his San Bernardino home about 8:00 a.m. to go to his business, Joe’s Tru Cool Air Conditioning. Around 9:00 a.m. a part-time employee arrived and found the shop doors open, Caponetti’s truck with the keys in the ignition, and a pool of blood behind a rear workbench that had been partially covered with tar. Caponetti himself was never located despite thorough investigations, and his disappearance remains unsolved.

At the time he vanished he was described as 5 feet 7 inches, about 145 pounds, wearing a light blue sweatshirt with worn lettering that read Joe’s Tru Cool, light blue corduroy trousers and brown high-top shoes. The case remains open and authorities continue to seek information.

If anyone knew Joseph, worked at or visited that shop, or has memories from April 1979 that could help, please share what is known.
