St. Valentine's Day Massacre Tommy Gun Display at The Mob Museum 

The St. Valentine’s Day Massacre was the darkest day in Mob history. On February 14th, 1929, assassins lined up seven men against the wall of a garage in Chicago and opened fire with Thompson submachine guns. News of the Massacre sparked a national outcry to take down the Mob and put an end to Prohibition, which was fueling gang violence across the country.
The bricks from that garage wall, as well as the ballistic evidence collected from the crime scene, are on permanent display in The Mob Museum. The Tommy guns used in the shooting are held by the Berrien County Sheriff’s Department in southwest Michigan. On several occasions over the years, the sheriff’s department has brought the Tommy guns to the Museum for temporary display, creating a grim reunion of artifacts from that fateful day.
