(Salem, OR) -- A Clackamas County grand jury has cleared a Sheriff's deputy and an Oregon State Police trooper in a shooting that killed Derrick Clark in June. The Oregon Attorney General prosecuted the case on a request from the Clackamas County District Attorney. Sheriff's Detective Daniel Ferguson and OSP Trooper Zachary Cole attempted to stop Clark in a vehicle. He fled and crashed in a ditch. When he got out of the car, he was armed with a gun, refused to drop it and ran. During the foot pursuit, he raised the gun and both officers fired killing Clark. The grand jury determined the officers' conduct didn't warrant criminal charges.
