A 12-year-old boy who allegedly fired a gun while showing it off at a Riverside middle school campus was in a juvenile detention facility last week, as the investigation continued into how he accessed the firearm.The youth, whose identity was not disclosed due to his age, was arrested Wednesday, March 16, on suspicion of possession of a gun on school grounds and reckless discharge of a firearm.According to Riverside police Officer Ryan Railsback, about 5 p.m. Wednesday, the boy was in a multi-purpose room at Loma Vista Middle School on Arlington Avenue when he allegedly opened his backpack and began exhibiting a pistol inside so that his classmates could see.“As he reached into the backpack, the gun fired and (the bullet) struck the table, then the ground,” Railsback said.
