February 14, 1929. St. Valentine’s Day Massacre remains the most notorious gangster killing of the Prohibition era. The massacre made Al Capone a national celebrity as well as brought him the unwanted attention of the federal government.Seven deaths: Frank Gusenberg, Pete Gusenberg, John May, Albert Weinshank, James Clark, Adam Heyer, and Dr. Reinhart Schwimmer.

As any mystery lover knows, a murder mystery would not be complete without a clear and well defined conclusion, but in the case of the St. Valentine’s Day Massacre, it has every element of the mystery, but the ending. Al Capone was never arrested for the crimes; the mysterious gun men were never identified and Capone never graced a reader or interested member of the public with an over dramatic confession. Instead, he was blandly indicted for tax evasion some years later and spent seven years in prison only to be released to retire in Florida, where he died from Syphilis in 1947.
