In July 1912, Lieutenant Charles Becker was named in the New York World as one of three senior police officials involved in the case of Herman Rosenthal, a small-time bookmaker and gambler who had complained to the press that his illegal casinos had been affected by the greed of Becker and his associates.
Rosenthal accused the police of demanding a large percentage of his illegal profits as protection in exchange for allowing him to continue to operate.
In the aftermath, Manhattan District Attorney Charles S. Whitman, who had made an appointment with Rosenthal before his death, said that he believed the gangsters had committed the murder at Becker's behest.
The events were so complex that the New York Police Department recalled 30 detectives from retirement to help investigate and were said "to know most of the gangsters.
He and his companion, Regina Gorden (formerly known as "Rose Harris"), were "so stupefied by opium that they offered no objection to their arrests," according to The New York Times.
