I understand what you're saying now, and I of course still agree there are lots more questions to be answered. I might have ranged a little far with my examples, but it's still largely relevant; being found frozen and close to dead would absolutely be cause for a general physical checkup, inside and out, in trying to figure out what the hell happened and what else you might need treatment for. Where you were found wouldn't really impact that bit, so I don't think it's surprising that they checked for internal injuries and I don't think it's surprising that the family would take finding such injuries as a sign of malfeasance. Your point about the injuries on her hands and forearms stands unchallenged, by the way - tissue damage could 100% look like contusions or lacerations. If it turns out she has broken bones in her hands, though...
