I think this article is from between 1931 and 1935, while Pop was still a Sergeant. Unfortunately, I was unable to narrow it further using the information on the individuals in the article.
Man Seriously Hurt in Brawl
Three Freight Jumpers Held After Fight in Ridgefield
One man is in Hackensack Hospital in a critical condition with a fractured skull, his alleged assailant was arrested and two men held as material witnesses as the result of a brawl in the Ridgefield yards of the New York Ontario & Western Railroad, at 2:30 o’clock yesterday afternoon.
Angelo Franino, 36, of 17 Murphy street, Newton, Mass., was struck on the head with an iron bar and brutally beaten. James Crattey, alias Patrick Kelley, 50, of Roseland, Mass., is in the Ridgefield jail charged with atrocious assault and battery. The witnesses, Richard Conors, 41, of Brighton, Mass, and William Donovan of Boston, are being detained in the Fort Lee jail.
The Ridgefield Park police received a tip of a disturbance at the place and upon learning its location notified the Ridgefield police. Sergeant Walter Gallagher arrived at the scene and made the arrests single-handed. Gallagher also summoned the hospital ambulance.
Gallagher said the men were riding freight cars and were temporarily stranded in Ridgefield waiting for another train. While there Franino told his companions his money was stolen, accusing Crattey. A general fight resulted during which Connors was struck in the face and lacerated.
Crattey was taken to Hackensack for questioning by the prosecutor’s detectives. After a charge was made against him there he was returned to the Ridgefield jail.
Prosecutor’s Detective John Gallione was stationed at Franino’s bedside to obtain a statement from him.
