I suspect the only info we'll get out of LE from now on will be in the courtroom, unless they have a press conference to announce more charges. Even then they would probably only announce the charges and very little other info.
I'm sorry if this has been posted here before, but I read through everything and didn't see the answer. If one of Ashley or Paul's siblings wants to become Abigail's legal guardian, he/she would probably be able to do that, right? I don't think social services will put kids in foster homes permanently if there are blood relatives willing to raise them, assuming those relatives don't have felony convictions that would make them unsuitable to raise a kid (i.e., child pornography, child abuse charges).
