About Louis Alterie

Lived 1886 – 1935 (aged 48). Louis Alterie was an American contract killer, rancher, hitman and ranch.

Louis "Two Gun" Alterie (August 2, 1886 – July 18, 1935), born Leland A. Varain and also known as "Diamond Jack Alterie", was a Californian who became a notorious hitman for the Chicago North Side Gang during the early years of Prohibition.

Early years Alterie was born Leland A. Varain in Northern California on August 2, 1886. He moved to Chicago as a young man, and eventually joined the predominantly Irish North Side Gang, which was headed by Dean O'Banion. Befitting his California background, Alterie was a Western enthusiast who wore a ten-gallon hat and two holstered Colt .45 revolvers and owned a ranch near Sedalia, Colorado. As well as being a top gunman for the North Side Gang, he also formed the Theatrical Janitors' Union and used his position as union president to extort money from theater owners.

Gang war with Chicago Outfit In the early 1920s, the North Side Gang's greatest rival was the Chicago Outfit, run first by John "The Fox" Torrio and then Al Capone. During this period a series of disputes over bootlegging territories and other matters led the North Siders into conflict with the Outfit and its allies, the Genna brothers of Little Italy. Alterie by some reports killed more than 20 Outfit and Genna gang members during this conflict which had erupted into a full-scale gang war in 1924 when O'Banion was murdered by Outfit gunmen in his floral shop on State Street in Chicago.
