The Marathon County Sheriff’s Office is investigating an incident where a 15-year-old girl had to be rescued from a bridge over the Rib River. A Wisconsin State Patrol trooper saw the girl hanging onto the bridge railing with one arm Friday afternoon. The trooper stopped his squad car and ran to the girl, reaching over and grabbing her arm. With the help of another driver who had stopped, the teenager was pulled to safety, then taken to a nearby hospital for a medical evaluation. Authorities haven’t said how the girl got into that situation and her name hasn’t been released.
