Machine Gun Jack McGurn, born Vincenzo Antonio Gibaldi, was a 33-year-old Italian-American mobster and hitman associated with Al Capone's Chicago Outfit. On February 15, 1936, McGurn was shot and killed while bowling at the Avenue Recreation Room in Chicago. The gunmen left a mocking valentine at the scene, indicating that McGurn had lost his job, money, jewels, cars, and houses, but at least he hadn't lost his trousers.
McGurn's death was the culmination of a series of events that saw
him fall out of favor with both the North Side and South Side gangs. His involvement in the infamous St. Valentine's Day Massacre of 1929, where seven members of the North Side Gang were murdered, made him a target for retribution. Despite being a prime suspect in the massacre, McGurn was never prosecuted due to his alibi provided by his girlfriend, Louise Rolfe.
The exact identity of McGurn's killers remains unknown, as no arrests were made in connection with his murder. The lack of concrete evidence and the chaotic nature of gangland politics at the time meant that the case was never fully resolved. McGurn was buried in Mount Carmel Cemetery in Hillside, Illinois.
McGurn's life and death are emblematic of the violent and tumultuous era of Prohibition-era Chicago, where gang rivalries and mob hits were commonplace. His story highlights the brutal reality of life as a mob enforcer and the ever-present danger of retribution within the criminal underworld.
