About or from 4th degree burns???
"4th degree burn
It is the most severe type of burn. It destroys not only the skin, but also the tissues underneath, right down to the bones. If a limb is damaged, it may become completely charred.
A dense scab, brown or even black, always forms in the burn area. The injured person is in a state of shock or coma. Burn disease develops extremely quickly - in the first hours after injury. Death is very likely. "
This is literally what she looks like.
