Dino Bravo
Cotroni had become involved in organized crime in the late 1920s, and in the 1930s was involved in "baseball bat elections" where he served as "muscle" for the Quebec Liberal Party and the Union Nationale, beating up supporters of rival parties and stuffing ballot boxes. As a result of Cotroni's work in "baseball bat elections", the Cotroni family enjoyed the protection of Quebec politicians for decades afterwards. Cotroni was uncle by marriage to professional wrestler Dino Bravo, believed by authorities to be involved in his organization for some time.
