A man was killed by police in Crofton, MD, in a struggle that injured an officer Sunday during a response to a domestic dispute where the man assaulted his mother. The injured Anne Arundel County officer remains hospitalized with serious head and other injuries suffered while responding to a family violence call in which he fatally shot a man, WBALTV11 reports.

After police arrived, the mother told the 911 operator that she couldn’t get to the front door, according to the department’s spokesperson, Jacklyn Davis. The front door was locked and there was no answer at the door, so officers entered the house and went up to the third floor.

The bedroom door was locked but after entering police said they found both the mother and her son. The son listened to officers’ orders to get on the ground, but Davis said when they tried to handcuff the son, he began fighting. A taser was deployed but Davis said it was “ineffective.”

Somehow, the officer was injured in the scuffle; he was brought to a trauma center, WTOP reported. The same officer who was injured shot and killed the son, Davis said. The suspect was pronounced dead at the scene.

As is the case with officer involved shootings in Maryland, the office of attorney general’s independent investigation division with review the shooting in partnership with state police. Under state law, the bodycam footage will also be released within 14 days as long as there aren’t technical difficulties, and the family has time to watch.
