while hanging in suspension, your body's muscles are stiff to some extent. Your skin and your organs will become discolored, leaving you yellow and purple. your tongue will turn grey and your lips blue. However, You will not relax all your muscles until the rope is removed from your neck. That is when things get messy. Not sure if this happens for everyone, but as I've observed: when the rope has been removed, blood will pour out from any openings in your face. this is due to the blood trapped in your head.
The police tried their best to remove all stains and clear the scene, but to this day there is a patch of dried blood on the floor. They had everyone leave the scene, so luckily no one was traumatized. Well, except the paramedics and police.
