Just curious where that information comes from? I don't remember seeing that stated as fact anywhere.
There is a deputy sheriff's incident report quoted in the Portsmouth paper. I had posted a link to it earlier. Not sure the word "pooled" was used but it was described as observing a "large amount" of blood in a room (living room) in which there were not any victims found.
