An enraged Becker ordered Rosenthal's death, and a quartet of killersâ€”Jacob Seidenshner (aka Whitet Lewis), Frank "Dago Frank" Cirofici, Louis "Lefty Louie" Rosenberg and Harry "Gyp the Blood" Horowitzâ€”rubbed out Rosenthal as he exited Big Tim Sullivan's Metropole Hotel at 142 West 43rd Street, just off Times Square, on the evening of July 16, 1912.
The four gunmen were found guilty of Rosenthal's murder on November 19, 1912.
Big Tim Sullivan was adjudged mentally incompetent in January 1913 and died that August.
On October 5, 1913 Lower East Side Gangster Big Jack Zelig was murdered on a Second Avenue streetcar just days before he was scheduled to testify at Charles Becker's trial. Becker was convicted, but on February 24, 1914, the New York State Court of Appeals (the state's highest court) overturned his conviction on the grounds that trial judge John Goff (1848-1924) had been biased against the defendent and further found that "haste seemed to become the essence of the trial." It ordered a new trial.
On April 14, 1914 Dago Frank, Whitey Lewis, Gyp the Blood, and Lefty Louie were executed at Sing Sing.
On May 22, 1914 Becker was again found guilty of ordering Rosenthal's murder.
Becker's prosecution propelled Manhattan District Attorney Charles S. Whitman into the New York State governorship.
On May 25, 1915 the New York State Court of Appeals confirmed Becker's conviction. On July 30, 1915 Charles Becker was electrocuted at Sing Sing. He was interred at Woodlawn Cemetery, Brooklyn, on August 2, 1915.
Becker's son by his first wife, Howard Paul Becker (1899-1960), was later elected President of the American Sociological Association.
