Charles Becker (July 26, 1870 – July 30, 1915) was a lieutenant in the New York City Police Department between the 1890s and the 1910s. He was convicted of first degree murder and executed for the killing of Herman Rosenthal, a bookmaker and gambler, in 1912 near Times Square.
Becker appealed and was retried but was convicted again. The day that Rosenthal was due to testify to a grand jury, he was murdered at 2 a.m. as he left the Hotel Metropole at 147 West 43rd Street, just off Times Square. Louis "Lefty Louie" Rosenberg, Jacob "Whitey Lewis" Seidenschner, Frank "Dago Frank" Cirofici, and Harry "Gyp the Blood" Horowitz were witnessed shooting him from their car, making no effort at disguise. The verdict was overturned on appeal on the grounds that Goff had been biased and that there was no independent corroborating witness to testify to the events since all of them had been involved in the crimes. and John Brennan (executed on December 2, 1926).
Becker continued to profess his innocence. The day before his execution, Becker told the warden,
<blockquote>"Sure, I told them to put Rosenthal out of the way, but I didn't mean they should kill him. I wanted them to get him out of town so he wouldn't blab. Killing him was Rose's idea and the others. They wanted to save their own skins."
</blockquote>
Jack Rose had served as a prosecution witness, as did Harry Vallon, Sam Schepps, and Bridgey Webber. They were underworld criminal figures who were believed to be involved in the crime but were promised immunity by the district attorney's office in exchange for testifying against Becker.
Charles Whitman, who was then Governor of New York, signed Becker's death warrant in 1915 and attended the execution. On July 30, 1915, Becker was executed in Sing Sing's electric chair by John Hulbert, New York's state electrician. The process took nine minutes, appearing to cause the man intense agony. For years afterward, it was described as "the clumsiest execution in the history of Sing Sing."
Becker was interred at Woodlawn Cemetery in the Bronx on August 2, 1915. He is buried next to his daughter.
Controversy
Beginning with Henry Klein in 1927, a number of authors have suggested that Becker was wrongly convicted. Andy Logan wrote a thorough account of this position in her Against the Evidence (1970), as she became convinced of his innocence in the murder through her research. Allegedly, District Attorney Whitman manipulated the evidence to implicate the corrupt Lieutenant. Becker was known to have assets that far exceeded his salary.
