Davis believed Hamilton was causing a disturbance. The report says when both teams were leaving the field, Hamilton and Davis began arguing. Davis claims Hamilton said he was going to kill him. The school’s Resource Officer says he tried to pull the two men apart when Davis pulled out a large pocket knife from his back pocket. Davis faces charges for aggravated assault.
