A police officer shot and killed a man during an early morning encounter outside the man’s New Jersey home, state authorities said.

The New Jersey attorney general’s office says two officers arrived a Mantua Township home just after 1:30 a.m. Tuesday in response to a 911 call.

The preliminary investigation indicates that one police officer fired his service weapon during an encounter outside the home, wounding the man, authorities said. Officers provided first aid and the man was taken to Jefferson Washington Township Hospital, where he was pronounced dead shortly before 3 a.m. Tuesday, officials said.

Officials said a .45 caliber handgun was recovered near the man, who was later determined to be the resident of the house. His identity hasn’t been released. No other injuries were reported. Details of the 911 call that sent officers to the scene weren’t immediately released.

The attorney general’s office is investigating pursuant to a statutory requirement that the office probe any death stemming from an encounter with a law enforcement officer.
