Cook County, Illinois, Sheriff’s police say a horse was killed when it ran into traffic in unincorporated Palos Township.

Sheriff’s police spokesman Bill Cunningham says the horse was on a riding trail near the Swallow Cliff Woods on Saturday afternoon when it bucked off a 42-year-old woman and ran away. The horse ran onto two-lane Illinois Highway 83 just west of La Grange Road, where it was struck and killed by a vehicle.

Cunningham says the woman who was bucked off wasn’t injured, and neither were the passengers in the vehicle which struck the horse.
