Joseph Azcona, 26, of Newark, was one of two city police officers shot at 6:37 p.m. in the area of Broadway and Carteret Street in Newark, according to the Essex County Prosecutor’s Office.

A 14-year-old shot and killed a police officer and wounded another Friday evening in New Jersey, authorities said, in a chaotic scene that witnesses described as seeing officers running down a busy street before they heard a volley of a dozen or more gunshots.
