Hi - I'm new here and haven't posted much, but have been following this thread with increasing sadness, anger and dread...just like all of you. Horrific doesn't come close to describing the situation.
Assuming that at 5, she probably attends pre-K or kindergarten at public school...has anyone interviewed Shaniya's school teachers? They are trained to recognize signs of abuse, which are quite obvious in children her age (who tend to blurt out anything and everything without worrying whether it's "appropriate", if mine are any indication). Odd things she has said, bruises, unusual body language or behaviors? They're required to report such things to authorities. Some folks have speculated that the legs crossed in the surveillance photos indicate abuse...things like that. Although, thinking of my own 5 year old, to me that could be because she's cold and/or that it's making her legs more comfortable (less squashed) when being carried that way. Anyway, that could help determine whether the mother has been prostituting her child during these three weeks. The cameras should also indicate whether a lot of adults were in and out of the trailer. I'm thinking this may have been a one-time thing, since those indicators don't seem to be surfacing.
And yes, I agree with many that viewing those hotel photos just makes my heart drop - the innocence and trust on her face. Ugh.
