A Baltimore police officer shot and killed a man in Northwest Baltimore early Sunday after witnessing a domestic assault, police said.

Police officers identified the man Sunday night as Michael Wudtee, 38, of the 8600 block of Greens Lane.

Between midnight and 1 a.m., officers were patrolling the area of the 4600 block of Liberty Heights Ave. in the Howard Park neighborhood. There, officers witnessed a domestic assault taking place in the parking lot of a gas station, police said.

While inside their cruiser, officers saw a man repeatedly punching and assaulting a woman — whom police described as his girlfriend — through the open window of a parked vehicle.

The officers pulled up next to the vehicle and attempted to confront the man, who immediately began to run, police said. The officers chased him to the 3600 block of Gwynn Oak Ave., where a fight broke out, according to police, who said the man "engaged and assaulted" one of the officers "in an effort to evade arrest."

An officer broke free from the fight and shot the man once in the upper torso, police said.

Wudtee was taken to Sinai Hospital, where he died about 1 a.m., police said, adding that the officer suffered injuries to his face and lower body from the fight and was treated at an area hospital.

Homicide detectives are investigating, as they do in all police-involved shootings, police said.

The girlfriend is cooperating with the investigation, according to police.
