You can't have it both ways. If he looked as bad as the pictures she's releasing to "shock" everyone, but she went AWOL from the hospital such that she can't be seen on any video camera, the mind reels at the possibilities. No mother would leave her child in that state. If she wasn't at the house, where was she? Drinking?
Excuse me? I'm not having it "both ways" and neither was either parent. they are not suspects no matter how you spin it.
Doctors can not diagnose internal injuries base on how a patient "looks" in photographs but they can certainly document suspected child abuse with photographs, which apparently is the case here.
