A former Prince George's County police officer who fatally shot a furniture delivery man in 2007 is seeking a new trial and a reduction of his original sentence.

Keith Washington has a post-conviction hearing underway. He is serving a 45-year prison sentence and was convicted in February 2008 of involuntary manslaughter, two counts of first-degree assault and two firearms counts.

Washington shot Robert White and Brandon Clark when the two men were delivering a bed frame to the former officer in his Accokeek home. Clark was killed and White was injured. During his trial, Washington testified that he shot the men in self-defense after they attacked him.

In addition to serving in the Prince George's County Police Department for 12 years, Washington also served as former County Executive Jack Johnson's deputy homeland security director.
