Are there any visible effects of an attempted hanging? I'm writing a comic where one of the characters attempts suicide via hanging himself, but he fails and ends up with a kind of red mark/bruise around his neck because of it, which he has to hide. (based on my guessing as to what happens with one's neck) Would there be any marks that were permanent or semi-permanent? I need to know so I can illustrate it correctly. If it's a more permanent thing or visible thing then I'd be able to use it as a kind of symbolism for his progression through life. I know this is an off-the-wall question. Thanks for your help, all.
