Google "Jahi Mcmath fingers" to see the photos of her apparently decaying body.
If you can stomach it, scroll down to see the photo of her finger with the hole in it and the other finger with the black blister on it.
(I'm married to a M.D. All my friends are M.D. We hang out with M.D.s If you will believe me, I will say they are cautiously waiting for "proof" of her not brain dead, but based on what they have seen thus far, believe she needs to be buried.)
They were all waiting for the "big reveal" and when that didn't happen, they were all like.. Ok. Back to brain dead....when they saw the finger photos, they were all like "ew. That's concerning"
I saw the picture you are talking about and I think that's actually a bit of an exaggerated description. There are clearly no "holes" in her fingers. They look like possible blisters/scrape marks, however I wouldn't like to speculate about what has caused them because I am not a medical professional.
