Anthony Ambrose, chief of detectives for the Essex County Prosecutor's Office, says 39-year-old Jose Alfaro was shot around 6 p.m. Saturday in the 700 block of Mount Prospect Avenue.
No other injuries were reported.
The shooting caps a violent week in the Newark area, with six people fatally shot since Christmas Day.
On Wednesday morning, three people were shot and killed outside a bar in nearby Irvington. The victims included the son of the bar's owner and a bouncer.
That night, two teenagers were killed when they were caught in the crossfire of a shooting in the South Ward.
One of them, a 13-year old girl, was taking out the trash when she was shot.
The gunmen in both shootings remain on the loose.
Newark has seen an overall jump in homicides in 2013, with over 100 this year. The last time the city reached double digits in murders was 2006, according to police department statistics.
The homicide total fell to 67 in 2008, a decrease that coincided with a heightened focus on violent crime after the grisly killings of three college-bound friends behind an elementary school in the summer of 2007 made national headlines.
Besides more aggressive policing of so-called quality-of-life crimes, millions of dollars in donations helped Newark police install surveillance cameras and a gunshot detection system in high-crime areas. In recent years, however, the murder rate has climbed back up to its pre-2008 levels.
Some of the city's community leaders are intensifying efforts to bring more federal money into Newark for public safety.
