I saw in one post that the mother had cuts and bruises. I wondered then if the cuts were scratches. I can't imagine if she was drowning that older child, that he wouldn't fight back. I didn't see that they'd been drugged either. Even if he was told to get in the water and lay down, it's human nature to struggle to breathe. If the kids were held under the water, there should be bruises from hands. I have rolled all this around in my head and don't see it! We are only privy to bits and pieces I'm sure.
Iirc I read they were deep cuts
