A Lehigh Acres Middle School at 104 Arthur Ave. has been charged with possession of a firearm on school property and alteration or removal of a firearm serial number. Investigators said the gun was found in a backpack belonging to Jevaughn Bravo, 13.

Authorities said that on Monday, Nov. 8, the school resource officer at the school was investigating the theft of a student’s cell phone. The theft was reported at the end of school as the busses were leaving, they said. The student who took the phone left the school on a bus.

Investigators said school administrators had the bus return to school and those students matching the description of the unknown suspect were asked to step off of the bus. An administrative search was conducted on the backpacks belonging to each of these students but the phone was not located.

However, during the search of one of the backpacks, an administrator located a handgun with an altered serial number. The backpack belonged to Bravo, administrators told investigators.

While talking to the media, the boy’s father said he belives his son was set up.
