A 16-year-old boy is facing multiple charges after authorities say he brought a gun into his school and threatened to kill another student.

Lee County sheriff’s deputies were dispatched at 5:41 p.m. Thursday to Smiths Station High School on a report of a student in the gym with a gun. Witnesses told 911 the armed suspect was leaving the school property in a white KIA.

Deputies arrived and stopped the suspect as he was trying to leave the campus.

The 16-year-old suspect was taken into custody.

Sheriff’s officials learned the teen had been in an altercation earlier with another student.

At some point during that confrontation, authorities said, the suspect went out to his car and retrieved a handgun. He then entered the school gym and threatened to kill the other student.

An adult female trainer who works with the school’s athletics program stepped in front of the suspect, shielding the student who was being threatened and told the suspect to leave.

The trainer told deputies the suspect was saying that he was going to kill the other student as he was pointing the gun in her face.

Sheriff’s investigators recovered a 9mm semi-automatic handgun from the suspect’s vehicle at the scene.

Authorities said the teen is charged as an adult but have not released his name.

He is charged with first-degree terrorist threat, second-degree burglary, certain person forbidden to possess a firearm and menacing.

He is being held in the Lee County jail on a $25,500 bond.

Anyone with additional information about the case is asked to contact the Lee County Sheriff’s Office at 334-749-5651 or Central Alabama Crimestoppers at 334-215-STOP (7867).
