Thomson ReutersROCKFORD, Wash. (AP) — A Washington state student accused of a deadly school shooting had been suspended for bringing threatening notes to school shortly before the attack. Freeman School District Superintendent Randy Russell tells The Spokesman-Review that the district followed protocol by suspending the student and sending him for a mental evaluation. The shooting occurred on the first day 15-year-old Caleb Sharpe returned from the suspension to Freeman High School in Rockford, the newspaper reported. Court documents say he pulled an assault weapon from a bag, but it jammed. Police say Sharpe pulled a pistol from his coat and shot and killed a 15-year-old boy, and wounded three female students. Sharpe was arrested and has yet to make an appearance in juvenile court.
