A teenager being tried as an adult in a fatal shooting in Rapid City has pleaded not guilty.

The 16-year-old boy is charged with aiding and abetting and aggravated assault in the death of 43-year-old Nathan Graham. He could face life in prison if convicted. Police say Graham was shot Aug. 17 after a fight and was declared dead the next day at a hospital. The attorney for the 16-year-old could request that the case be moved back to juvenile court, where proceedings are not public. It’s not known if the attorney will make that request. A status hearing is scheduled Nov. 19. A 14-year-old boy also is charged in the case, in juvenile court. Prosecutors could seek to have him moved to adult court.
