Fort Hood soldier Vanessa Guillen bludgeoned to death while on duty on base, family attorney says...

The article states the attack happened in the Arms Room. A bludgeoning attack would cause massive bleeding. Forensics would find traces no matter how well they cleaned. Unless the whole story is still not being told.

SSG George Holtje - This story has more holes than swiss cheese. There is so much we are not being told.

To be fair, the article doesn't say there was no blood found. It's likely there's plenty of blood in that arms room but they didn't release that part of the story to the media yet.
I suspect they've known about it for a while.

You can have a fatal head injury with minimal to no loss of blood and I have seen it. A ran an assault case last year where most of her blood was in her hair and had another patient that his head was caught between an ATV and the ground and barely a mark. He would have been able to have an open casket funeral if the family desired. Blood dries very dark and it would not take long on a rifle rack where it would not be easily seen and we know where there are soldiers, there is always a mop and pine sol.
