A Colt Detective Special .38 revolver linked to Frank Gusenberg, one of the seven victims of the St. Valentine's Day Massacre. Gusenberg, a North Side Gang member, was shot 14 times during the St. Valentine's Day Massacre and lived for three hours after the shooting, but when he was questioned on the scene about the perpetrators, the mobster refused to cooperate. The massacre was later determined to have been orchestrated by Al Capone's criminal organization and was a result of a power struggle between the two gangs. It is believed that this firearm fell from Gusenberg's pocket as he attempted to crawl to safety following the massacre. Courtesy of the Mob Museum
