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.

Joseph Azcona, 26, was still in his police car when he was shot on Friday night, the Essex County Prosecutor's Office said.
