A former Seymour High School student is facing a felony charge after he posted a picture of an AR-15 style rifle and indicated something was going to happen at the school yesterday.
17-year-old River Erdmann of Appleton is now home schooled. Investigators say he posted the picture to a Snapchat group with a caption about an incident a year ago where a student brought a weapon to school. They say they found an airsoft rifle during a search of Erdmann’s house. He’s charged with making a terrorist threat.
