The Blood Stain on Sam's Pants

This is a blood impression left on the pillow, but there's another shot that I think is a lot more. Hang on real quick. These are not the pants of someone who just killed someone. He could have gotten rid of them. We don't know. Look at that blood stain on the bed. It's almost in body shape. That's a lot. And do you know, since I can't see it in the photo, was that pillow up by the headboard?
