SEATTLE - A prosecutor told jurors a man accused of killing a Seattle police officer in an ambush on Halloween in 2009 was angry about what he saw as an increasing number of police-brutality cases.
Opening statements began Tuesday in the trial Christopher Monfort, who authorities say was conducting a one-man war on police.
He's charged with aggravated murder and attempted murder in the shooting and also arson for a fire that damaged police vehicles at a city maintenance yard.
Monfort has pleaded not guilty by reason of insanity. Prosecutors are seeking the death penalty if he's convicted, even though Washington Gov. Jay Inslee has ordered a moratorium on executions as long as he is governor.
Monfort is accused of shooting Officer Tim Brenton and Officer Britt Sweeney as they sat in a patrol car. Sweeney survived.
