Snyder's eventual arrest for Paul's murder would result in his turning state's evidence and revealing to police the existence of "labor sluggers" used by businesses and unions alike during the early 1900s.
Similar cases would include Abe "Kid Twist" Reles, a former hitman for Murder, Inc., whose testimony resulted in the conviction (and later execution) of Louis Buchalter in 1941, and Genovese crime family mobster Joe Valachi, who appeared before the McClelland Committee in 1963 to expose the modern-day Cosa Nostra.
According to one account, Rosenzweig and half a dozen henchmen found Jewbach before the trial and had his men hold him down while the gang leader cut out a large piece of his lower lip.
[3][4] At a meeting with Assistant District Attorney Royal H. Weller, which was arranged by reform lawyer William Travers Jerome, Snyder made a full and remarkably detailed confession of both his criminal career and outlined labor racketeering activities in a series of conferences taking place during late 1914.
Snyder described these activities in a crude but straightforward manner of "beating up scabs" which included, but not limited to, knifing or "bumping him over the head with a pipe".
[5] Not long after, Rosenzweig was arrested with his lieutenants "Little Hymie" Bernstein and "Tough Jake" Heiseman for the murder of Philip Paul.
[6] On the morning of June 24, 1915, Snyder was attacked by three convicts from Italian Harlem while prison guards were serving breakfast.
Snyder's attackers, according to prison guards, called him a "rat", "squealer" and "District Attorney's friend" during the assault.
[7] On the day of the assault, Snyder had been scheduled to appear before the Criminal Term of the Supreme Court for sentencing of the plea of manslaughter for the murder of Paul Philip.
