FRESNO, Calif. (KFSN) — Action News has learned a second horse at the Fresno fairgrounds has died.

The California Horse Racing Board reports the 6-year-old male developed pneumonia in a stable at the racetrack.

The fair’s racing director says the horse named Tulane Tryst showed signs of an illness this past Friday.

The horse was treated before veterinary professionals recommended euthanasia and the cause of his illness is still being determined.

This comes as authorities investigate the loss of a five-year-old horse that went down during a race on Sunday.

Cry me a Runner stumbled in the stretch to the finish line.

The animal rights group PETA shared a video recorded by someone at the race, showing the moment the animal and her jockey fell to the ground.

The rider is okay, but the injured horse was euthanized.

The fair released statements following both incidents expressing sadness over the loss of the horses and highlighting its veterinary care and safety record.
