A 17-year-old student at Mosinee High School is charged with one felony and four misdemeanors after guns and knives were found in his pickup. Authorities say the weapons were in the truck, on school property, while Logan Kasat was in class.  A female classmate told school officials about the weapons, saying she was afraid to go to class with Kasat.  He told police the pistol belonged to his grandfather and the rifle was used for hunting.  Kasat said he forgot the guns were in his pickup and he had no intention of harming anyone.
