Nebraska authorities are searching to find out who shot a beloved retired rodeo horse last month.

According to the Scottsbluff Star-Herald, the horse, J.K. Tonto, was found Nov. 17 by the grandfather of Kayellyn Hall, a rodeo competitor. One of the horse’s shoulders was shattered by a bullet on the family’s ranch in Minatare and it had to be euthanized.

“He was my first horse,” said Kayellyn Hall, who had owned J.K. Tonto since she was 7 years old. “Rodeo is my life,” she said, “and he is the horse that got that started.”
