Isadore Blumenfeld (September 8, 1900 – June 21, 1981), commonly known as Kid Cann, was a Romanian Jewish-American organized crime enforcer based in Minneapolis, Minnesota, for over four decades. He remains the most notorious mobster in the history of Minnesota. He was associated with several high-profile crimes in the city's history, including the 1924 murder of cab driver Charles Goldberg, the attempted murder of police officer James H. Trepanier, and the December 1935 assassination of investigative journalist Walter Liggett. He is also thought to have participated in the fraudulent dismantling of the Twin City Rapid Transit street railway during the early 1950s. Blumenfeld was convicted of violating the federal Mann Act in 1959 and, after a short prison term, retired to Miami Beach, Florida, where he and Meyer Lansky operated a real estate empire. He was involved in organized crime in Miami Beach and Havana, Cuba, until his death. Life Early life Blumenfeld was born in 1900 in the Romanian shtetl of Râmnicu Sărat, Buzău County, to an Orthodox Jewish family. According to U.S. Immigration and Naturalization Service documents, his parents emigrated to America in 1902 via the port of Duluth, Minnesota. His father, a Romanian Jewish furrier named Phillip Blumenfeld, settled his wife Eva Blumenfeld (née Abromowitz) at 824 S. Seventh Street Minneapolis. During childhood, Isadore had to leave school and support his family by selling newspapers on Minneapolis' "Newspaper Row." At the time, the best selling locations had to be held by force against gangs of other boys. Blumenfeld would also tell stories of how he had made extra money picking up bus tokens and reselling them. Enraged by the poverty of his family, he turned to running errands for the pimps and madams of Minneapolis's red light district. Two tales are told of the origins of his famous nickname. According to one legend, he picked up the name during a brief attempt at boxing. Another story told by his fellow North Side Jews alleges that young Isadore Blumenfeld would always lock himself in the outhouse (that is, the "can") to avoid gang fights in the neighborhood. Kid Cann indignantly denied both versions. Journalist Neal Karlen confirms that both stories were false, "Kid enjoyed not only fighting, but killing." Prohibition With the onset of Prohibition, Kid Cann and his brothers Harry Bloom and Jacob Blumenfeld (alias "Dandy" and "Yiddy Bloom"), were transformed from small-time hoods into major organized
