Workers removed the remains of 43 horses who died in a racetrack barn fire that killed two men.

Investigators indicated they are still trying to pinpoint the cause of the blaze that swept swiftly through a Lebanon Raceway barn early Saturday.

They have ruled out arson as a possible cause.

Stunned horse owners, trainers and stable workers came to the scene Sunday to find debris that had been pushed into twisted, charred piles.

Warren County Fair Board member Chris Lutmer says officials wanted to quickly remove the horse remains to ease anxiety. He said that for most owners and workers, the horses were like members of their family.

The track has seen at least four fires since 1990, when 35 horses were killed in a blaze.
