Saint Valentine's Day Massacre - Murder Weapons

Murder Weapons

The two Thompson submachine guns (serial numbers 2347 and 7580) found in Fred Dane’s (an alias for Fred Burke) Michigan bungalow were personally driven to the Chicago coroner’s office by the Berrien County District Attorney. Ballistic expert Calvin Goddard tested the weapons and determined that both had been used in the massacre. One of them had also been used in the murder of Brooklyn mob boss Frankie Yale, which confirmed the New York Police Department’s long-held theory that Burke, and by extension Al Capone, had been responsible for Yale's death.

Gun No. 2347 had been originally purchased on November 12, 1924 by Les Farmer, a deputy sheriff in Marion, Illinois, which happened to be the seat of Williamson County. Marion and the surrounding area were then overrun by the warring bootleg factions of the Shelton Brothers and Charlie Birger. Deputy Farmer was documented as having ties with Egan’s Rats, based 100 miles (160 km) away in St. Louis. By the beginning of 1927 at the very latest, the weapon had wound up in Fred Burke's possession. It is possible he had used this same gun in Detroit’s Milaflores Massacre on March 28, 1927.

Gun No. 7580 had been sold by Chicago sporting goods owner Peter von Frantzius to a Victor Thompson (also known as Frank V. Thompson) in the care of the Fox Hotel of Elgin, Illinois. Some time after the purchase the machine gun wound up with James "Bozo" Shupe, a small-time hood from Chicago’s West Side who had ties to various members of Capone’s outfit.

Both submachine guns are still in the possession of the Berrien County Sheriff's Department in St. Joseph, Michigan.
