A 27-year-old man killed by Montgomery County police officers was armed with an AR-15 rifle and wouldn’t comply with officers’ commands — prompting seven officers to fire their weapons on Monday night, officials said on Tuesday. The man, Antoine Duane Goodrum, of Germantown, was wearing a tactical vest and “carrying numerous extra magazines loaded with ammunition,” police said in a statement. He was pronounced dead at the scene.

About 9:15 p.m., police received a call from a man saying he had just shot and killed his grandmother and his roommate inside a residence along Red Robin Terrace in Germantown. Police arrived, determined the man had left, heard gunshots and set up a perimeter. The officers met up with Goodrum near the intersection of Great Seneca Highway and Grotto Lane. Officers negotiated with him for about 12 minutes before he was shot, authorities said.

Officers checked the residence and found the grandmother and roommate unharmed. Police found vehicle parked outside with numerous bullet holes, and determined the gunshots came from inside the residence. All seven officers have been placed on paid administrative leave pending the outcome of the investigation, officials said.
