I think that Crystal's computers are NOT going to reveal much, if anything. It was probably more to keep her kids occupied.
She didn't even use a cell phone in her name. She used a fake name. I don't think Pimps do much on-line. They even speak in code, they are not going to trust a computer.
The computer may establish a time that she was home - possibily - I really doubt anything further than that.
I think her computer would be a treasure trove of information.
I want to know why the cops seized it.
