"Hannah, 15, was riding Quaxx 2, a 12-year-old Holsteiner gelding, in an equitation class when the horse tripped and suffered a rotational fall. The fall was unrelated to a jumping effort. The EMT responded immediately, and Hannah was transported to Sarasota Memorial where she was pronounced dead. The horse was uninjured in the accident." reads the statement of the USEF. 
 
"Hannah from Webster, Fla., was a very talented up-and-coming young rider who trained with Robin Swinderman. She was known for her passion for horses, her natural ability, and her work ethic."

The internet is filling up with #rideforhannah posts, as the equestrian community expresses their support.
