Capone was widely assumed to have been responsible for ordering the 1929 Saint Valentine 's Day Massacre in an attempt to eliminate Bugs Moran , head of the North Side Gang . Moran was the last survivor of the North Side gunmen ; his succession had come about because his similarly aggressive predecessors Vincent Drucci and Hymie Weiss had been killed in the violence that followed the murder of original leader Dean O'Banion
