NEWARK - Authorities say three shootings in Newark last night have left at least one person dead and 12 wounded.

Acting prosecutor Carolyn Murray said in a news release today that a 15-year-old boy was fatally shot and seven others were wounded at about 10 p.m. last night in the South Ward.

Authorities identified the boy as Aziz Stewart, of Newark. He was pronounced dead at University Hospital.

Murray said the other victims, both males and females, ranged from 12-32 years old. Acting police director Samuel DeMaio said the shootings appeared to be targeted.

Acting Director DeMaio urged residents to help identify the shooter involved in last night's violence, "I have the utmost faith in the residents of our great city and am confident that if anyone witnessed anything or knows the actors involved in this heinous shooting, they will help the police department."

Earlier that evening in the city, authorities say four people were injured by gunfire near the corner of Halsey Street and Branford Place in the city's East Ward.

Police say that officers responding to that shooting found a person with a gunshot wound at the scene. Investigators later learned three others had gone to University Hospital with gunshot wounds they say they suffered at the same location. All four were hospitalized in stable condition.

Authorities reported a third shooting in the city's West Ward. One woman was injured by gunfire.

Anyone with information about any of the shootings are asked to call Newark's 24-hour "Crime Stoppers" anonymous tip line at 877 695-8477 and 877 695-4867 or the Essex County Prosecutor's Office Homicide/Major Crimes Task Force tips line at 1-877-847-7432.
