NEW YORK CITY (WTVO) — A security guard working on the set of “Law & Order: Organized Crime” was shot to death on-location early Tuesday morning.

According to Variety, the unnamed crew member was sitting in his car at 5:15 a.m. in Brooklyn, where filming was to take place later that day. Variety said the man was part of set security to reserve parking and guard trucks.

An unknown assailant approached the car, opened the door, and shot him, according to reports of the incident.

Our hearts go out to his family and friends and we ask that you respect their privacy during this time.”
