Churchill Downs has responded following a string of horse deaths connected to the racetrack since late last week, including three here on Kentucky Derby week. Two horses were euthanized because of injuries, and two others collapsed and died on the track. Churchill Downs issued a statement Wednesday afternoon, saying two horses trained by Saffie Joseph Jr. have died of "cause yet to be identified"; Parents Pride on Saturday and Chasing Artie on Tuesday. The officials added that two other horses received "musculoskeletal injuries from which they could not recover"; Wild on Ice received his injuries while training on dirt last Thursday and Take Charge Briana during a turf race on Tuesday. Wild on Ice was taken to the Rood & Riddle Equine Hospital in Lexington for care, but officials say both were ultimately euthanized for "humane reasons."
