The fire started around 12:30 Tuesday morning when flames broke out at the True Prospect Farm, located at 248 Hood Road in West Marlborough.
Eleven horses were in the barn when flames broke out. Three people, identified as Lillian Heard, Caitlin Silliman, and Ryan Wood, were able to rescue several horses from the blaze. Tragically, Action News has learned that six horses perished in the fire.
Of the five that were rescued, four of the horses are currently in treatment at The University of Pennsylvania New Bolton Center.
