Rosenthal murder case
The Becker-Rosenthal trial was a 1912 trial for the murder of Herman Rosenthal by Charles Becker and members of the Lenox Avenue Gang. The trial ran from October 7, 1912 to October 30, 1912 and restarted on May 2, 1914 to May 22, 1914. Other procedural events took place in 1915.
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 who had complained to the press that his illegal casinos had been badly damaged by the greed of Becker and his associates. On July 16, two days after the story appeared, Rosenthal walked out of the Hotel Metropole at 147 West 43rd Street, just off Times Square. He was gunned down by a crew of Jewish gangsters from the Lower East Side, Manhattan. In the aftermath, Manhattan District Attorney Charles S. Whitman, who had made an appointment with Rosenthal before his death, made no secret of his belief that the gangsters had committed the murder at Charles Becker's behest.
At first, John J. Reisler, also known as "John the barber," told the police that he'd seen "Bridgey" Webber running away from the crime scene directly following the killing. He recanted under duress from gangsters the next week, and was charged with perjury.
The investigation was covered on the front page of the New York Times for months. It was so complex that the NYPD recalled thirty retired detectives to help investigate; they were said "to know most of the gangsters." One of these old-timers, Detective Frank Upton, formerly of the NYPD "Italian Squad," was instrumental in the July 25, 1912, arrest of "Dago" Frank Cirofici, one of the suspected killers. 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.
