Sheriff says student was armed with shotgun at Colorado’s Arapahoe High School; made no effort to hide it or conceal it; also a “device” possibly a molotov cocktail, was found inside the school, per bulletin on Breaking News.

Other students called shooter “troubled”, so this is probably a mental health situation.

“Colorado does not provide a minimum age to possess rifles or shotguns. Colorado also provides no minimum age for the purchase of a handgun or a long gun, although federal age restrictions still apply.”
