Opening arguments Tuesday in Seattle cop-killing trial

SEATTLE (AP) — Opening arguments are scheduled Tuesday in Seattle in the trial of a man accused of killing a Seattle police officer on Halloween in 2009.

Christopher Monfort has pleaded not guilty by reason of insanity. Prosecutors say they'll seek the death penalty if he's convicted.

Monfort is accused of ambushing Officer Tim Brenton and Officer Britt Sweeney as they sat in a patrol car. Sweeney survived and Monfort also is charged with attempted murder.

Monfort was wounded by police about a week later during his arrest in Tukwila. He is paralyzed from the waist down and confined to a wheelchair.
