MONKTON, Md. (AP) — Charging documents against a Baltimore County teen accused of plotting to shoot people at his school reveal that he said he was planning much more and was motivated by years of bullying.

The documents, released Wednesday, say the Monkton 10th-grader told police he was going to kill his parents Nov. 3, drive to his school, shoot the school police officer, and then take the officer’s gun to “kill as many teachers and students as he could.”

The documents say the teen also said he had made several bombs and was going to blow up the school, George Washington Carver Center for Arts and Technology.

Police recovered a handgun, three crude, homemade explosives, a suicide note, and a journal with all the boy’s plans from his home.

He was arrested Saturday.
