Joe Adonis
During the mid-1920s, Bernstein began expanding his gang's activities to other major cities in the country. He became an associate of New York mobsters Joe Adonis and Meyer Lansky, and later became a partner in several syndicate gambling casinos in Miami, Florida. He started Club Manitou of Harbor Springs in 1929. After his brother Ray was imprisoned for his part in the Collingwood Manor Massacre, Bernstein devoted the rest of his life in an effort to get his brother released from prison.
