Both he and the second victim, 32-year-old Nelson Hilario, were taken to St. Joseph's Regional Medical Center, Passaic County Prosecutor Camelia M. Valdes and Paterson Police Chief Ibrahim Baycora said in a joint release.
Vasquez was pronounced dead a little over a half-hour later.
Valdes and Baycora didn't say whether any suspects had been arrested or identified.
It was the Silk City's 19th homicide this year.
