OKLAHOMA CITY (AP) — A witness to the fatal shooting of an unarmed teenager by an Oklahoma police captain says the teen appeared to try to surrender before he was shot.

Del City police Capt. Randy Harrison is charged with first-degree manslaughter in the March 14, 2012, death of 18-year-old Dane Scott Jr.

Harrison has pleaded not guilty and faces a minimum of four years and a maximum of life in prison if convicted.

Scott's friend, 17-year-old John Lockett, testified Wednesday that Scott was running from Harrison and put his hands up as if surrendering before he was fatally shot.

Lockett says Scott led Harrison on a high-speed chase that ended in a collision. He says Scott and Harrison scuffled before Scott wriggled free and ran away.
