Nitti's grave can be found left of the main Roosevelt Road entrance, about fifty feet from the gate. Nitti ran Capone's liquor smuggling and distribution operation, importing Frank and Rose Levitt divorced in 1928, and shortly thereafter he married Anna Ronga, daughter of a mob doctor and former neighbor of the Nittis in the 1920s.With Nitti calling the shots, the Chicago Outfit branched out from Court testimony later insisted that the murder attempt was personally ordered by newly elected Anna Nitto died on November 19, 1940, in Mercy Hospital, Chicago, from an unspecified internal ailment.In 1943, many top members of the Chicago Outfit were indicted for Frank Nitti died on March 19, 1943, at the age of 57.While the name Frank Nitti has become infamous in American criminal history, the man himself never at any point in his life referred to himself as anything other than his legal surname "Nitto"; only the police, media, and fringe mobsters called him Nitti. Despite his nickname ("The Enforcer"), Nitti used Mafia soldiers and others to commit violence rather than do it himself. Two months later, Cermak was shot and killed by Giuseppe Zangara, a Calabrian immigrant. Speculation has persisted regarding the interment of a suicide in a Catholic cemetery. Although Frank Nitti has gotten the reputation over the years as the right-hand man of gangster Al Capone and a feared killer in his own right, this has actually proven not to be the case. The day before his scheduled grand jury appearance, Nitti had breakfast with his wife in their home at 712 Selborne Road in Riverside, Illinois. At the time, Cermak was talking to President-elect Franklin D. Roosevelt. Nitti was not a troublesome prisoner, but found the year-and-a-half confinement in a cell difficult because of the closed-in space. Most historians believe, corroborated by Zangara's own comments and a note left behind at his room, that he intended to kill Roosevelt but missed and hit Cermak instead. This picture would cause some to incorrectly infer that Paul Ricca was the new boss of the Chicago mob. He was the second child of Luigi and Rosina (Fezza) Nitto and a first cousin of Al Capone.
On December 19, 1932, a team of Chicago police, headed by Detective Sergeants Harry Lang and Harry Miller, raided Nitti's office in Room 554, at 221 N. LaSalle Street in Chicago. Police Chief Allen Rose of North Riverside rushed to the scene with a sergeant and several beat patrolmen, and recognized Nitti immediately. He then loaded a .32 caliber revolver, put it in his coat pocket, and walked five blocks to a local railroad yard. In 1943, many top members of the Chicago Outfit were indicted for extorting the Hollywood film industry. Nitti was head of operations, with Jake "Greasy Thumb" Guzik as head of administration and Tony "Joe Batters" Accardo as head of enforcement. The studios had cooperated with The Outfit to avoid union trouble (unrest itself stirred up by the mob). Anna Nitto died on Nov. 19, 1940 in Mercy Hospital, Chicago, from an unspecified internal ailment. Among those prosecuted were Nitti, Phil D'Andrea, Louis "Little New York" Campagna, Nick Circella, Charles "Cherry Nose" Gioe, Ralph Pierce, Ricca, and John "Handsome Johnny" Roselli. To the right of the gate is the family plot containing the grave of Al Capone, marked by a six-foot white monument stone. Frank Nitti was another one of Al Capone's top associates and ran Big Al's smuggling and liquor distributing operation. Accardo was an enforcer for Al Capone and Frank Nitti, Gladden said. The next several years of his life are poorly documented, and little can be ascertained. Nitti ran Capone's liquor smuggling and distribution operation, importing whisky from Canada and selling it through a network of speakeasies around Chicago. He may have worked in the Williamsburg neighborhood of Brooklyn around 1911.

According to Nitti biographer Mars Eghigian, Nitti's age, brilliance, and reputation in the underworld made him Capone's personal choice for successor, rather than younger, less experienced mobsters such as Ricca or Murray Humphreys.
