NEWARK, N.J. (PIX11) — Two children – ages 4 and 7 – and a man were shot while in a car in Newark Wednesday evening, officials said.

The shooting happened at Irvine Turner Boulevard and West Kinney Street around 5:50 p.m., according to Newark Public Safety Director Brian O’Hara. The two kids and a 30-year-old man were hospitalized, officials said. The mother of the boys was also in the car and was uninjured.

Witnesses described the incident as an apparent drive-by shooting. They said the shooter pulled up in a car right next to the victims’ car and opened fire.

Lamont Lanham, a security guard who works in the area, said he helped get them to a hospital quickly.

“As I approached the car, the [man] opened the door and he asked if I can get them to the hospital because he didn’t think he could make it,” said Lanham. “I noticed the kids in the back. One of the kids had a lot of blood on his arm. There was another kid in the car seat that seemed to be unresponsive. I ask the mother if she could drive. She said ‘yeah’ and she jumped in the car. I got them to the hospital as fast I could, making a path for them to get there.”

The shooter was using a car stolen from Kearny, New Jersey, that was taken when it was left unlocked with the key inside, according to O’Hara.

“We need people everywhere to stop leaving their cars unlocked with the key in them,” O’Hara said in a statement. “This kind of carelessness is repeatedly contributing to violence and enabling more serious harm to occur in our communities.”

No arrests had been made. Authorities described the conditions of the victims as stable, as of Thursday morning.
