Rectal assault could produce the same results I mentioned and potentially perforate the colon. Again, arterial bleeding could occur but more likely venous bleeding. My guess is involuntary incontinence as a result of fright, etc. or blanket could have been used for wiping after BM. This was not an ideal living environment and mother obviously did not bond with this child and she very likely was not being cared for. We have not seen a actual amount of stool that was present on blanket. Could have been grossly dirty or small amount....who knows. OR if child has had frequent, chronic rectal violation, she may be incontinent of feces due to lack of sphincter tone. Everything is speculative at this point.
The one thought I had when I read she was in the hotel room about an hour and dogs hit on towel was that she was taken there and cleaned up (incontinent of stool). This may not have even been a transfer point but an attempt to prepare a dirty child for transfer somewhere else. In my mind, an hour to get room, get to room, secure child, rape child, clean up self and child and get out just seems short period of time. Not saying it doesn't or couldn't happen, but I think it would be close and risky. Rapid more violent attack by adult mule on child would render child in undesirable state to a buyer awaiting "product". JMO
