They didn't want Warmbier to die in their custody
From what I'm reading, Warmbier has intensive damage to his brain, what does that mean?
Is he going to be a vegetable or unable to ever wake up?
If you don’t wake up within a week, from a coma, your prognosis goes straight down hill.
Barring a miracle, this will be his life until he passes.
Yes to both questions....and his brain is basically destroyed throughout all areas. Lack of blood to the area is sort of like turning off your car and pulling out the engine....no matter what you do to start the car it won’t go without the engine.
