A Mercer County Junior High student who was arrested for bringing an unloaded gun to school last week won’t be returning to class this school year. The youth will remain detained through at least early June, his next scheduled detention hearing, which is after classes dismiss for the school year. At today’s hearing in Mercer County Circuit Court, it was revealed that his family has other firearms in the home. The student was taken into custody after a routine search uncovered the 32-caliber handgun in his locker last Friday. It was not displayed and no threats were made. The minor has officially been charged with unlawful use of a weapon at school. Mercer County State’s Attorney Meeghan Lee says the family had the gun locked, but the youth was able to somehow unlock it through a keypad.
