A school investigation identified 46-year-old Melissa Harloam-Garrison as the person suspected of giving the student and additional kids fentanyl.

Harloam-Garrison is a bus driver and campus security guard who lives on campus in a cottage with her husband, the school said.

Officers searched the on-campus home and found more than a hundred suspected fentanyl pills, two handguns and various types of ammunition. 

Harloam-Garrison was arrested and booked into the Robert Presley Detention Center on charges of child endangerment and various illegal drug and firearms violations. She is being held on $50,000 bail.

Her husband, 58-year-old David Garrison, was also arrested and booked on charges of possession of a firearm on campus and possession of a firearm by a prohibited person. His bail was set at $25,000.

The investigation is still ongoing.
