ST. PAUL, Minn. – Two 16-year-olds in Minnesota are facing juvenile charges after social media posts from last month showed them flashing handguns at their St. Paul charter school.

Investigators said the loaded gun was in the teen’s backpack when they apprehended him as he got off a bus near his apartment.

Another student is shown in the post displaying a handgun, which was later determined to be a replica gun.
