Two teenagers in Florida have been accused of planning to carry out a school shooting.

During a press conference on Thursday, as reported by Meredith Deliso for ABC News, Lee County Sheriff Carmine Marceno said that a teacher from Harns Marsh Middle School in Lehigh Acres had received “concerning information” on Wednesday about an eighth grade student. The information given to the teacher alleged that the student in question was “possibly in possession” of a gun in his book bag. From there, the teacher alerted a school resource officer, as well as school administrators, prompting the removal of the student from class.

An administrative search was performed, per Marceno, with no weapon ultimately discovered in the bag. Found in the bag, however, was a map of the school featuring locations for each of the facility’s interior cameras. Detectives are then said to have identified two students allegedly involved “in a plot to carry out a school shooting.” The students in question are aged 13 and 14.
