On this date, Feb. 14, 1929, seven associates of North Side gangster George “Bugs” Moran were shot to death in a Chicago warehouse by gunmen allegedly working for his main rival Al Capone.
The bloodbath became known as the St. Valentine's Day Massacre.
The killers posed as police officers to infiltrate Moran’s garage, lined up the seven men against a brick wall and mowed them down with machine gun fire and shotgun blasts.
The gangland slayings made national headlines and brought unwanted attention to the Capone gang.
Two years later, Capone was convicted of income tax evasion and sentenced to 11 years in federal prison.
Despite numerous suspects and theories, the crime remains unsolved.
The storage building at 2122 North Clark Street, now demolished, remains a popular tourist attraction.
