Yeah, wouldn't yours be too if you were starved to death??? They could NOT determine if she was PVS - that was more behavorial than physical. YOU really need to see the video I have - you'd see how responsive she was!
They had evidence in the CT scan that her brain was significantly damaged. COupled with the behavioral portions of the PVS diagnosis (and the subsequent autopsy that proved it) - I think they got this one right.
