Joseph Patrick Breen, known as Joey, was 23 when he vanished after going out on the evening of November 12, 1979. Although some records link the case to Chicago, details place him in the South Boston neighborhood of Boston, Massachusetts, that night. He never returned home and has not been seen or heard from since.

At the time he disappeared he was described as a white male, 5 feet 6 inches, about 140 to 150 pounds, with black hair, hazel eyes and a scar on his right arm. Last-worn clothing was a blue jacket, a white shirt with red trim, a green sweater and blue jeans. The Boston Police Department has periodically sought public help, and the case is entered in national missing-persons databases.

The investigation has produced few concrete leads and the circumstances of his disappearance remain unresolved. If anyone knew Joseph, saw him in South Boston on November 12, 1979, or has information that could help, please come forward.
