A passenger in the car that killed three Girls Scouts and an adult supervisor three years ago is scheduled to be arraigned in Chippewa County Court next month. John Stender was in the vehicle driven by Colten Treu when it hit the victims as they were cleaning up trash along a highway in Lake Hallie. A fourth scout was injured. Stender told investigators he grabbed the steering wheel in an effort to avoid going into a ditch. He faces charges of harboring and aiding a felon and intentionally abusing a hazardous substance. He and Treu were accused of “huffing” an aerosol chemical before the incident.
