Former Prince George’s County police officer Keith Washington, 51, is seeking a new trial and a reduction in sentence in connection with a 2007 shooting in his home.

Washington was convicted in 2008 of shooting Brandon Clark, who was killed, and Robert White, who was wounded. The men were delivering furniture to Washington’s home when he shot them. Washington maintains he acted in self-defense, according to NBC4.

Washington, who served as deputy director of the county’s Homeland Security Office under former County Executive Jack Johnson, was convicted with involuntary manslaughter, two counts of first-degree assault, and two counts of handgun use. He was sentenced to 90 years in prison, with all but 45 years suspended. 

His post-conviction hearings are scheduled for Wednesday and Thursday.
