That is a very odd crime scene. Why is there gun blast on the wall 5 feet above the bed? Did they just come in like John Wayne and blast the drywall? Notice too there is no blood spatter on the wall that is just the drywall spatter. (You get this info from watching CSI a lot)
Why is there blood on the far wall.
Why is there blood on the other side of the foot board. Looks as if it was wiped.
That's not gun blast, it's bomb debris......
