Many questions surround this case, starting with:

Why is Fox 13 reporting that a note written by one of the girls said, "Go to kill in bathroom," when the note obviously said "Go to Bill in bathroom." ?

After the girls were taken into custody, investigators searched their homes and found a hand-drawn map of Bartow Middle School with the words, "Go to kill in bathroom," written on it.

Also no mention of one of the girls writing about the voices in her head:

“My eyes are red. I’m under my bed with only the tears I shed. You came to comfort so please don’t leave until I’m dead. You know why I cry, they will not leave the voices in my head. I’m so fed up with it.”

It's also interesting that police were already on campus for a previous threat that news reports do not describe or link to this incident:

Extra security was already on campus Tuesday because of threats made a day earlier.

CNN reported it this way: https://www.cnn.com/2018/10/24/us/florida-middle-girls-allegedly-wanted-to-kill-classmates/index.html?utm_term=image&utm_source=twCNN&utm_medium=social&utm_content=2018-10-25T04%3A01%3A03

Additional police were already on campus because a student had notified a teacher of a rumored threat to students.
