A student brought an unloaded gun onto a Greenhaven neighborhood school campus on Tuesday, police said.
The 9-year-old brought the gun to Sol Aureus College Preparatory School on Gloria Drive in a backpack and had shown the weapon to a classmate, police said. Staff was alerted to the presence of the gun and confiscated the weapon.
An investigation into how the student got the gun revealed that it was obtained from the home of a relative of the student. It was determined that neither the parents nor the relative were negligent, police said in an activity log.
The student was charged with bringing a firearm into a school zone, police said.
Earlier this month, Sacramento police arrested a 17-year-old boy after he brought a loaded handgun on to the American Legion High School campus in Oak Park.
The handgun was spotted in the boy's waistband and later confiscated.
