From the article:
Police used canine units to search the school, as part of a regular sweep of the school grounds. There had been no threats or incidents to prompt the search.
Police found one boy was in possession of marijuana and drug paraphernalia. The boy then indicated he also had a shotgun in a case in his pickup truck which was parked in the school’s lot. Police said the weapon was legally cased and stored, but it was against the law to bring it onto school grounds. The boy also had a pocketknife, police said. The boy was charged with unauthorized storage of a weapon, possession of drug paraphernalia and marijuana possession, police said.
Every gun in the hands of a child must first pass through the hands of an adult.Police said a pellet gun was found in another student’s locker. That student was charged with unauthorized storage of a weapon and possession of ammunition without a Firearm Owner’s ID card, police said. Both students were taken to the Kendall County Jail.
