Update
Fire investigators have stated that there does not appear to be any "criminal intent" for the fire. I suppose that this is about the only good news in all of this.
Investigators have not officially released the names of the dead, but the horsemen have essentially stated that trainers Ronnie Williams and James "Turtle" Edwards were in the barn when the fire started and nobody has seen them since, which unfortunately means they had to be the two that lost their lives in the blaze.
