For anyone who has trouble, like me, picturing without a picture, I have made this initial diagram. Please excuse the roughness - it's done with a finger paint app.
Here are the bullet wounds, bruises and abrasions I think we have so far ( inc. three bullet entrance wounds but only two exits at the back.)
I left out any possible left arm injury as I am really not sure if there was one.
I've included a close up of that odd little wound between the second and third finger that the pathologist found.
