Virginia school officials are alleged to have downplayed concerns about the six-year-old boy that went on to shoot a teacher, including that he said he wanted to light her on fire and watch her die, The Washington Post reported.

Police said the child eventually shot teacher Abigail Zwerner earlier this month as she taught her first-grade class at Richneck Elementary School in Newport News.

Authorities have said that the shooting was “intentional” and “not accidental” but have not provided further information.

The Post obtained a message written by a Richneck teacher through the local teachers union that reveals alarming details about the boy’s alleged behavior.

The account claims that the boy wrote a note to Zwerner which said that he hated her and wanted to light her on fire and watch her die. When she reported the note to Richneck administrators, Zwerner was told to drop the matter, the account claims.

On one occasion, the boy threw furniture and other items around in class, which led to the other children hiding under their desks, per the account.

The account also claims that in another incident, the boy barricaded the doors to a classroom and prevented a teacher and students from leaving.
