From a Bloodhorse article:
"More than 100 horses are thought to have perished in the massive tornado that hit the Moore, Okla. area May 20 in addition to the human lives that were lost."
"The farm's stalls and barns took a direct hit from the tornado, which was estimated to be on the ground for 40 minutes as it demolished everything in its path. It was estimated to be 3.2 kilometres wide. Three and a half of the facility's five barns were reported to be swept away.
Vann said debris had been found on the Orr property from the city of Moore all the way to Tulsa, Okla., which is approximately 90 miles from the farm. "Right now they are going through and looking at just what they lost," he said."
"I tried to let some of the horses get loose and free out of their stalls so they'd have a chance," said Hite, who suspected the tornado was on its way moments just before it touched down.
"Hite said he works for trainer Mark Lee, who had several horses stabled at Celestial Acres. Lee trains horses that have won stakes at Remington Park, Sam Houston Race Park, Fonner Park, Horsemen's Park, and Delta Downs."
"Equine equipment and feed-related donations in the Oklahoma area can be arranged by calling Red Earth Feed & Tack 405-478-3424. Orr has also set up a Paypal account for those wishing to donate to the farm.
Celestial Acres is located 20-25 miles from Remington Park, which was not believed to have sustained significant damage from the tornado. A representative from the track, which is dark May 21, could not be reached.http://www.bloodhorse.com/horse-racing/articles/78408/more-than-100-horses-dead-due-to-tornado
