A New Jersey police officer was shot and killed Monday morning while sitting in his personal vehicle, county prosecutors announced.

The male Sayreville officer, who was not named, was off-duty at the time and was a nine-year veteran who worked in an undercover capacity, ABC6 reported.

The officer was found about 7:15 a.m. near the Amboy Cinemas and may have been investigating a suspicious person report, according to NBC New York, citing sources.

It’s unknown if the officer returned fire or if police are pursuing a suspect. Spokesman James O'Neill said that department was investigating after being alerted to a report of a body near the former movie theater off Route 9.

The Amboy Cinemas closed nearly a decade ago.
