Deriek Crouse

Virginia Tech Police Officer Deriek W. Crouse

BLACKSBURG, Va. (AP) _ A big contingent of law enforcement officials is expected to honor a fallen brother when a funeral is held for a Virginia Tech police officer who was killed in the line of duty.

Officer Deriek W. Crouse’s funeral service is scheduled Monday at Cassell Coliseum on the Tech campus in Blacksburg. Gov. Bob McDonnell will deliver remarks.

Crouse was making a traffic stop last Thursday when police say a 22-year-old student at a nearby college walked up to his cruiser and shot him.

Shortly after that, Ross Truett Ashley was found dead of a self-inflicted gunshot wound in a nearby parking lot.

State police investigators are still attempting to establish a motive for what appeared to be an unprovoked attack on Crouse.

Crouse left five children and his wife.
