The incident occurred on August 16 at Lakeland Senior High School, about 45 minutes from Tampa, during a lockdown exercise under a Polk County risk-protection order.
The police questioned 16 students about the incident. The teacher told the students if he was a school shooter, he would grow improvised explosive devices (IEDs), then "fire a few rounds and wait for everyone to hide, then push a button and boom – all would die," he said Student witness.
The teacher also said, "He would put a bomb in the corner and put nails in as a splinter," another student at the police said.
CNN does not name the teacher because he was not charged. When the teacher was interviewed by an officer, he told the police he was a former US Navy and his statements were a joke.
"As a former Marine, he should be seen as the person protecting and not compelling students to question whether their teacher wants to harm them," wrote Detective Justin Conatser, who submitted the risk-protection order, in his report.
The police ransacked Teacher's house and vehicle, but found no weapons.
The teacher has no criminal history, but a temporary ex-party risk-protection order states that the teacher "may be seriously mentally ill or have recurrent mental health problems".
The Polk County School District states that the teacher is on administrative leave while investigating the case. School District Leader Jacqueline M. Byrd said in a statement that the district "fully cooperates with law enforcement investigations and conducts our own internal investigations." more than 1
