Plot hole: Doctor Gordon is an experienced doctor and surgeon, but he never notices that the "corpse" in the room doesn't show any signs of decaying, as he should.
Suggested correction: The movie takes place over a matter of only a few hours. Oftentimes, corpses can take 2-5 days before they start showing any significant early signs of physical decomposition. He'd have no reason to notice a lack of decay because decay wouldn't be expected in such a short timeframe. They're under the assumption he had killed himself relatively recently, especially given the blood puddle is still relatively "liquidy."
