Mobster Al Capone was believed responsible for the 1929 mob rubout that became known as the St. Valentine’s Day Massacre. Seven mobsters were gunned down by firing squad on a winter morning in Chicago. While widely suspected of ordering the hit, Capone cleverly made sure to be in Florida when the hail of bullets was fired.
Among the gangster's homes was also a mansion in Miami Beach, which was on the market for $15 million in 2018.
Here's the full story, including a look at his Florida mansion with the late Bob Massi, "The Property Man".
