The Washington Post reported Saturday that educators at the school said the teacher, Abigail Zwerner, had repeatedly asked school officials for help with handling the boy but was ignored.
...The Post reported a separate message from a teacher who said the boy once wrote a teacher a note saying that he hated her and wanted to light her on fire. The teacher who received the note told administrators about it but was told to drop the issue, according to the message.
...The message said the boy also once threw furniture and other items in the classroom, leading other students in the class to hide under their desks, according to the Post. He also barricaded the doors to a classroom and blocked a teacher and students from leaving, the message reportedly said.
