Ellis says the girls and boys in Future Farmers of America, whose pigs died, are doing well but that FFA animals to some students are "like a family pet."
Ellis told The Associated Press that the last student left the barn around 10 p.m. Sunday. The fire was reported around 1:10 a.m. Monday.
Ellis says a fire marshal determined the blaze was an accident, possibly electrical, but that the fire did not involve a heat lamp.
