Also note how skinny he is compared to his other photos.
In my opinion the only thing established about Paddock was that his body was dead in the room. The top half you can see a lot of blood at his chest. but they don’t show his right hand or abdomen. Note: No or very little blood on the revolver claimed he used to kill himself.
I would not expect much blood on a revolver used in a suicide with the muzzle in the mouth. The back of the head is blown out; the revolver recoils away from that and, depending on how it was held, the position of the arm or arms, and the original position of the body, usually falls to rest on or a little ways a way from the body. In 7% of the cases, it comes to rest more than a 30 cm from the body, just as shown in the photos.
24% of the time, it stays in the hand.
