Event Details

Commemorating its 13th Anniversary, The Mob Museum will host a special single-day showcase of artifacts from the February 14, 1929, St. Valentine’s Day Massacre

Believed to have been orchestrated by Chicago Outfit boss Al Capone, on Valentine’s Day in 1929, seven members and associates of the North Side bootlegging gang were lined up against a wall and shot to death.

Members of the Berrien County, Michigan, Sheriff’s Department — which possesses the two Thompson submachine ("Tommy") guns used in the gangland slaying — will be on hand to discuss the historic firearms and answer questions. 

Other Massacre-related artifacts will include the blueprint of the Tommy Gun, provided by the Auto-Ordnance Corporation to Dr. Calvin Goddard, and the only firearm found at the scene of the crime, Frank Gusenberg’s .38 revolver.

A reconstructed version of the brick wall from the St. Valentine's Day Massacre will also be on view as part of the museum's permanent collection in the upstairs gallery.

Additional Activities Include:

  • The Las Vegas Metropolitan Police Department’s K-9 unit will conduct a drug demonstration in the Event Plaza from 11 a.m. to 12 p.m. followed by a meet and greet from 12 p.m. to 1 p.m.
  • Reformed mobster Frank Calabrese Jr. will share his Family Secrets presentation from 11 a.m. to 7 p.m.
