SS, AS and VF were bludgeoned and stabbed to death, and PS was stabbed and burned alive. I think it's safe to assume there was a bloodbath in that home. And they had been tortured too ...
ETA: I forgot to include the post I was replying to. This is in reply to the poster, I think rkf, who questioned if the crime scene would have been bloody.
I think it must have been, because the fire department immediately knew they were in a crime scene. I guess the people strapped to chairs helped them figure that out. But I was wondering if more information had been released by LE that I missed. Thanks.
