Lake County deputies have released a note, witness statements and a map from the student who is accused of plotting to kill his teachers, along with himself.
Lake County Schools said on Wednesday another student at East Ridge Middle School in Clermont reported the 12-year-old boy's plan to school officials on May 19.
A school resource officer then got involved, according to school officials, and the student was expelled.
Deputies said the sixth-grade student had a knife in his possession when they interviewed him on May 19 and a "little black book" that had a printed out drawing of the school with X marks where he wanted to kill teachers.
His book included notes on "world domination," in which he mentions wanting to harm countries. The boy also had a page with blood that apparently came from a fight with his brother.
According to the report, the student had five teachers he wanted to kill, along with anyone in the front office. The student had then planned to kill himself in front of his peers in the cafeteria, deputies said.
A student stated that he joked like this all year, according to the witness statements.
The student was taken to Lifestream Behavioral Center for evaluation under the Baker Act, or Florida Mental Health Act, according to deputies.
Deputies said the student had recently been suspended for 10 days and was in the process of "alternately placing the student." It's not clear why the student was previously suspended.
No weapons were found in the boy's room at his home, according to the report.
