WENATCHEE, Wash. -

A Washington State Patrol investigation has cleared the Wenatchee police officer who fatally shot a suspect in an undercover drug deal.

The patrol said Monday that Officer Scott Reiber was justified in using lethal force on Dec. 12 when he shot 43-year-old Robert Harris of Wenatchee.

Reiber was being dragged through the drive-through lane at a fast-food restaurant after the officer had pulled over the car to arrest Harris.

The officer was treated at a hospital for minor injuries.
