A Kansas couple wants to know why someone shot and killed their daughter’s 11-year-old horse.

Gary and Ara Carbonneau are offering a $1,000 reward for information leading to the arrest in the shooting of the chestnut filly named Aimee. The couple’s insurance company added another $1,000 to the reward fund.

The couple says someone trespassed on their property last Tuesday and shot the horse at point-blank range. Topeka veterinarian Ed Kester says the bullet passed through the horse’s liver and stomach before lodging in her intestine.

The Jefferson County Sheriff’s Office is investigating.
