Okay, here is what bothers me about this so far. FS says she puts the child down in the dining room on the floor and hugs her goodnight, then leaves. She says " she was still in the house when I left."
NOTE= She does not say she was still alive, just still in the home.
So FS is supposedly gone. Mom is passed out drunk. So that leaves QS, her BF, and the mystery 3rd man, and possibly mom's bf, still in the home.
If the child was assaulted in the home I think there would have been evidence left behind, and there were 6 other children there. I think it would have been seen.
So did one or more of them take her out of there @ 4 am? Why would the aunt allow that? Didn't she have kids there too? [I am not sure if she did, actually I seem to remember someone saying they thought she might have had a recent miscarriage.]
Anyway, I think it would have been either a repayment of a big drug debt or something, like Shaniya, OR a revenge motive of some kind. But who was the target of the revenge? The mother? It is hard to believe she would have that angry or evil of an enemy. It seems more plausible that a twisted Sex Offender just saw the opportunity and jumped on it. Especially since it was so unplanned, so sloppy, the way the gas was bought.
I am thinking that QS and her bf found themselves in debt somehow to an evil twisted sex offender and they let him in the house that night to save themselves.
