A loaded gun was found in an elementary student’s backpack — and the person who placed it there was the child’s mother.

Warren County Sheriff’s Department responded to a threat of a weapon at Hickory Creek Elementary School on Monday.

The District Attorney reports that Kristen Holland placed a loaded gun inside her child’s backpack.

A school staff member discovered the firearm at 7:45 a.m. as they assisted the child into school while carrying their backpack. The staff member was unaware of the firearm before assisting the child.

Following the discovery, school personnel notified law enforcement.
