Abraham "Bo" Weinberg (January 7, 1900 – September 9, 1935) was a Jewish New York City mobster who became a hitman and chief lieutenant for the Prohibition-era gang boss Dutch Schultz.
 As Schultz expanded his bootlegging operations into Manhattan during Prohibition, he recruited Abe Weinberg and his brother George into his gang.
 Abe Weinberg would become one of Schultz's top gunmen during the Manhattan Bootleg Wars and was a later suspect in the high-profile gangland slayings of Jack "Legs" Diamond, Vincent "Mad Dog" Coll, and mob boss Salvatore Maranzano.
Vincent "Mad Dog" Coll (born Uinseann Ó Colla, July 20, 1908 – February 7, 1932) was an Irish American mob hitman in the 1920s and early 1930s in New York City.
 Coll gained notoriety for the alleged accidental killing of a young child during a mob kidnap attempt.

 He was never formally charged with the crime, and came to wider attention as a suspect after his death when his son Steve Hodel, a Los Angeles homicide detective, accused George Hodel of killing Short and committing several additional murders.
