A Silver Creek teenager arrested earlier this week after allegedly discharging a handgun on the campus of Armuchee High School is now facing several additional charges, according to Floyd County Jail records.

Authorities say 17-year-old Scott Ryan Ferguson was allegedly loitering in the north parking lot of Armuchee High School on Martha Berry Highway Tuesday when he discharged a firearm into his own leg while another student was nearby. The incident reportedly triggered multiple 911 calls and caused a substantial disruption to normal school operations.

Investigators say the firearm was later abandoned on school property.

Ferguson was initially charged with possession of a pistol or revolver by a person under the age of 18, carrying a weapon within a school safety zone, and reckless conduct.

Jail records now show additional charges have been filed, including criminal trespass, loitering on school grounds, disruption of a public school, and an additional count of reckless conduct.

Authorities also stated Ferguson had previously been banned from all Floyd County School System campuses prior to the incident.

The investigation remains ongoing.
