Pretty much.
I think the focus of LE/DA is really on the principal here. PF. I think they know for the most part what happened and how and are solidifying their evidence.
I agree with
@riolove77 that it's unlikely the woman actually participated in the murder but wasn't arrested. Unless they just didn't have evidence to show that. But she told someone about the solicitations, before the murder, so it seems she was probably freaked out to some degree.
I'm not giving her a pass though. I think she's a sleazy, opportunistic criminal with extremely low moral character, willing to participate in a terrible crime against another woman and mom. And not because she was afraid. I think she wanted the "man".
But IMO justice is being served here. He's the prime goal. And she will face more justice than the legal system will mete out.
So it's not perfect but I'm very satisfied. And excited about this development.
