If as reported she is brain dead I agree with you. She is dead.
My heart breaks for her mother. I hope the hospital offered he more than “she’s brain dead and we are taking her off life support.”
It has happened occasionally that “brain dead” people have woken up.
They make mistakes in hospitals too.
“I hope the hospital offered he more than shes brain dead and we are taking her off life support.”
I hope that they didn’t send the bill for the tonsillectomy yet with the obligatory “pay within four hours of receipt or bill will be presented for collection” red stamp.
This is a sad story, but this sort of thing can and does happen. ANY surgery is risky - some more so than others.
