NEWARK, N.J. — 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.

The slain officer, 25-year-old Joseph Azcona, was part of a Newark police intelligence team that had gone to capture a suspect in an illegal weapons investigation when the officer was fired on in his vehicle, authorities said.

“He didn’t even get a chance to step out of the vehicle before he was struck,” Emanuel Miranda, Newark’s director of public safety, told a Saturday morning news conference with Newark’s mayor and top prosecutor.

The other officer who was struck was hospitalized with injuries that were not life-threatening, authorities said. Newark Mayor Ras Baraka called the shooting a “heinous, callous disregard for humanity.”

Teen Charged With Murder

Police took five people into custody, including the 14-year-old who was charged with murder, attempted murder and possession of illegal weapons, Essex County Prosecutor Theodore N. Stevens II told the news conference.

The 14-year-old was shot and hospitalized with injuries that were not life threatening, Stevens said.

Stevens did not identify the boy or the other four people in custody who he said were undergoing questioning by investigators Saturday. Stevens and Miranda gave few other details about what led police to the group that fired on Azcona, the ensuing police response or the shootout. One gun was recovered, Stevens said.

Azcona was a five-year veteran of the Newark police force and was promoted to detective two years ago.

Witnesses Describe Chaotic Scene

Azcona and the other officer were shot around 6:37 p.m. in the area of Broadway and Carteret, authorities said earlier. Witnesses said they heard a string of gunshots after they saw officers running down the street on a commercial strip between a McDonald’s and White Castle restaurants near the Passaic River.

Witness Randy Mejia told WCBS-TV right before he heard gunshots that he saw officers running down the street.

“It sounded like a car accident and it went boom, boom, boom,” Mejia said.

Officer Pronounced Dead at Hospital

The wounded officers were taken to University Hospital in Newark, where Azcona was pronounced dead around 2:30 a.m., Stevens said. Azcona’s mother, father and brother were at the hospital to see him and grieve after the shooting, Miranda said.

Police declined to identify the officer who was wounded.
