Answer 2

The St. Valentine's Day Massacre was an infamous gangland killing that occurred in Chicago. The killing resulted from the rivalry between two notorious criminal gangs of Chicago : the South Side Italian gang led by Al 'Scarface' Capone and the North Side Irish gang led by George 'Bugs' Moran.

On February 14, 1929, men reportedly sent by Capone machine-gunned 7 men associated with the Moran gang, inside a warehouse garage on North Clark Street. All but one died on the scene and the other shortly thereafter. At least two of the killers were reportedly disguised as Chicago police, which may have led the victims to acquiesce rather than engage in a shootout.

The St. Valentine's Massacre occurred on February 14, 1929. There were seven men murdered that day.
The St. Valentine's Day Massacre was the murder of 7 men who were related to the North Side Irish gang (led by Bugs Moran) in Chicago in 1929. Not all of those killed were actual gang members, but they were all involved with the gang. The murders happened as a consequence of the rivalry between the South Side Italian gang and the North Side Irish gang. Each gang was involved in the illegal trade of alcohol (this was in the Prohibition Era), and that's why they were fighting (they were in competition against each other). The murderers were involved in the South Side Italian gang (led by Al Capone).

The St. Valentine's Day Massacre remains the most notorious gangster killing of the probitionera.
