PITTSGROVE, N.J. (CBS) — A New Jersey State Police Trooper remains hospitalized after authorities say he was shot in Pittsgrove on Saturday night. The incident happened shortly after 10:30 p.m. at the Harding Woods Mobile Home Park on Harding Highway.

Authorities say the trooper was investigating a home invasion that allegedly took place Saturday afternoon at the mobile home park when several people approached the trooper in a car and confronted him.

After the trooper identified himself, authorities say the individuals opened fire and wounded the trooper. Authorities say the trooper was struck in his leg.

Officials say the trooper underwent surgery on Sunday morning at Cooper University Hospital in Camden and is currently recuperating.

Investigators say the trooper also discharged his gun during the incident.

Neighbors described the chaotic scene on Sunday.

“You can tell the difference between gunshot and fireworks. It sounded like 20 rounds went off at one time,” neighbor Michael Baez said.

“It didn’t sound like it stopped. It sounded like they had time to reload and more shots were fired,” neighbor Richard Burke said.

Authorities are being tight-lipped about what led up to the incident, but neighbors say a woman was badly beaten inside, adding she was not the intended target.

“From what I understand, they beat her up pretty good,” Baez said.

No charges have been filed at this time in the incident as the investigation is ongoing.
