If you want a realistic prop to adorn your torture chamber or Halloween dungeon this Halloween bloody body in a bag certainly fits the bill. An inflatable body fits inside a bloodied plastic bag which you can tie up and hang from the ceiling.
Just blow up the inflatable life size body and put in inside the bloody bag. Looks like this chap has met a torturous end.
You could hang it in a dark corner or hang it in your themed serial killer scene.
