“I now literally have a plan of seriously hurting… killing… murdering people in my high school. And a playlist to do it”

The Maricopa County Sheriff Office says the girl had access to guns at her home, but never brought firearms to Red Mountain High School in Mesa.

The agency says investigators arrested the girl at her home Thursday morning and that she admitted to posting the threat.

According to the sheriff’s office, when she posted the comment three days ago, she had serious thoughts and even plans to shoot people and bomb the school. She told deputies she had been planning this in her head before last week’s massacre in Connecticut.

She told investigators she even thought about cutting the wires on the security carts on campus in order to slow the response.

The girl’s parents are being cooperative and admitted to having a few guns in the home.

Deputies found a semi-automatic .40 caliber handgun, a .357 revolver and a .22 revolver in the house. The guns had trigger locks and were kept in a gun safe. They were not seized.

The post continued on by saying “I WORK at the high school as a student teacher basically … which is why no one can find out about me somewhat accidentally planning to blow up the school. (and yes … it would be super easy …).”

In the interview by sheriff’s detectives of the girl’s parents both said their daughter has a history of mental health issues, has been seen by a psychiatrist, and had recently been inquiring about where the guns were being kept in the house. The father said he was alarmed by his daughter’s comments and took the additional safety precautions of placing trigger locks on each gun and safeguarding them in a gun safe.
