A man was killed and two Maryland state troopers were wounded in a domestic incident Friday in the western part of the state.

The two troopers were treated and released by midday from the University of Maryland Shock Trauma Center, officials said.

The suspect, identified as 66-year-old William Charles Mackenzie, was pronounced dead at a hospital.

Just after 11 p.m. Thursday, Maryland State Police in Cumberland responded to a call for a domestic situation at a home in the 11000 block of High Germany Road in Little Orleans, in Allegany County about 110 miles northwest of the District.

Police said they believe Mackenzie was inside the home when troopers arrived. His wife said they argued and he pulled out a handgun. She told police he threatened her with the gun and said, "This ends today."

The couple fought and fell to the ground. As they fell, she told police, the gun fired. She escaped the home and called police from a neighbor's house, authorities said.

Her husband barricaded himself in the home, and police tried to get him to surrender. Early Friday, a State Police tactical unit went into the home and Mackenzie fired at them, police officials said in a statement.

The two troopers were struck in the "lower extremities." The troopers returned gunfire and hit Mackenzie, police said.

As officers were going into the home, a fire started. Officials said they believe Mackenzie ignited the blaze, which was extinguished.

Officials said that Mackenzie's wife was not injured and that no one else was home at the time.

Both state troopers have been with the department for six years, officials said.
