PHOENIX - A Mesa high school student, who was arrested last month for allegedly plotting to kill herself and some of her peers, will not be tried as an adult.
After a court hearing Monday, it was determined that the unidentified girl will be released to her parents and will need to wear an electronic monitoring device.
The 16-year-old student was also a teacher’s assistant at Red Mountain High School, near Brown and Power roads.
On Dec. 20, the Maricopa County Sheriff’s Office said she was arrested for threats she posted on a YouTube channel.
The Maricopa County Attorney’s Office requested that she be tried as an adult, which was turned down Monday.
The case went before Judge David Udall, and it was determined that the girl is not a threat, but she would need to go into counseling.
This all started when the girl posted threats on a YouTube channel owned by a transgender community in Toronto, Canada.
The owner of the channel contacted Toronto police, and they then tracked down the poster, MCSO said.
Toronto police then contacted MCSO, which launched an investigation soon after.
Part of the post reportedly said the following: "I now literally have a plan of seriously hurting... killing... murdering people in my high school. And a playlist to do it."
According to MCSO, the post went on to say, "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...)"
MCSO went to the home of the girl's parents where the girl admitted to making the post among other statements.
Detectives entered the home and found a semi-automatic .40 caliber, a .357 revolver, and a .22 revolver, according to MCSO.
Detectives also seized two computers in the home to process more evidence.
Sheriff Joe Arpaio said in a news conference that the girl planned to bomb the school and shoot others.
The girl told detectives she had been planning this before the Newtown, Connecticut school tragedy the week before.
In interviews with detectives, the girl's parents said she has a history of mental health issues and has been seen by a psychiatrist, according to MCSO.
The girl was taken to the Maricopa County Juvenile Detention.
The girl was facing juvenile charges of one count of computer tampering and one count of threatening and intimidating.
