The Outfit in Chicago had a strong presence and influence throughout most of the 20th century. Many legends and books describe the well-known members and activities.
Between 1919 and 2005, it has been estimated there have been at least 1100 Outfit slayings and only 14 convictions. In some cases, the hit men were whacked before they could be arrested. In other cases, the bodies were never found. The Outfit was adept at taking care of business.
In 2005, the FBI launched Operation: Family Secrets with indictments for 18 gangland murders that occurred in the 1960’s, 70’s and 80’s. They indicted 14 Outfit members.
Family Secrets: The Case That Crippled the Chicago Mob (Chicago Review Press) covers the Spilotro murders and much more in a revealing look at organized crime. The book, written by Chicago Tribune reporter Jeff Coen, covers the trial of the Outfit bosses in 2007.
For factual information, that book is highly recommended.
