Interesting there's not a word that her little brother was the "victim's" best friend and that's why the mother let him go out of state to live with the family. The mother knew the whole time where he was. Sounds like both the mother and the boy were already screwed up and absent/divorced/whatever dad finally stepped up to the plate.
I take it you're speaking of the boy's mom in Texas? Guess she had no way of knowing that Silva and Silva's mom were untrustworthy. The Silva family is known to me. Our now 15 yo's attended the same elementary school. They have always been pretty liberal but the mom and sister took it to new levels recently.
