At 12:30 a.m. on Tuesday, May 31, a fire destroyed Boyd Martin’s barn at Phillip Dutton's True Prospect Farm in West Grove, Pa. Six horses died and many others were injured.

Martin’s assistant Lillian Heard was staying with a friend above the barn for the night and smelled smoke shortly after midnight.

“They rushed downstairs and started pulling horses out,” said Kate Brown, who works for Dutton and lives on the farm. “We don’t know what caused the fire.”
