How long after death have their necks been cut open?
That I do not know, I do not believe it was mentioned.
Also, I hear that muscles becomes less strong when you die (for example, how you need only 5 kg on weight to compress the carotids on a dead neck), do you think this is a factor on why this happened? I mean, why the muscles rip and the carotids tear?
I'm not sure whether or not the carotids become less strong too after you die (less resistant, should I say?).
I'm very tired, hope this reply makes sense, if not, let me know.
They actually did an in-depth analysis of all the different possible injuries and compared cadaver weight, noose type (if i remember correctly), how long they were suspended before they were found, how high up they were suspended, did they jump or not, the whole 9 yards. I really wish I had it still because it would be a very informative read for you. Honestly, that whole post was great since it had other studies that analyzed hangings. I wonder how it got deleted since, to my knowledge, we can't delete posts unless a mod removes it.
As for the muscles, if you're aware of the death process of hanging, you lose muscle tone around 2-4 minutes in (iirc). Which only further pressures your carotids, and presumably pulls on your muscles harder. Perhaps muscle and artery tears are only a concern once you've reached this point. But I also seem to recall another study that also covered individuals who were saved before death, and the possibility of developing an aneurysm in your carotid increased; to the point of it being an actual risk for survival post-attempt. But again, I do not have this study either, and my memory is not the best so I would advise you to also take this with a grain of salt.
Fuck, I really wish I could just drop some links and let you research for yourself. I checked out these studies like 8-10 months ago and my brain is scraping for this knowledge like a rusty hard drive lol. so, sorry about that.
