 Troopers say they don't know why yet, but Sumner's state-issued minivan collided with Frepon's personal vehicle, a pickup truck on Highway 62 about a mile east of Meeker. They say Sumner was dead at the scene, and Frepon had to be flown to a hospital in Oklahoma City for surgery, but is in stable condition. Officials say they're devastated by the incident. They say the two men graduated from the same academy last year. Dick Lofton, 1023 KRMG, Tulsa's News and Talk.
