A Princeton man accused of taking a loaded gun into Princeton High School has pleaded not guilty to a charge of felony unlawful use of a weapon. 18-year old Blake Schmidt was arraigned yesterday at the Bureau County Courthouse. Schmidt is accused of entering the school on November 16th with a loaded shotgun as classes were letting out. Police say he pointed the gun at himself, but no one else. A trial date of March 19th has been set for Schmidt, who is out after posting five thousand dollars bond.
