There’s also the (at least?) two civil lawsuits by “Zanny” and Texas Equusearch. Will anything come of those?
Murder is not a federal crime...they can probably stretch it, and charge her with “violating the daughter’s civil rights,” but it is a...that’s be honest...a white person...so.
Secondly, I sincerely doubt that the US Attorney down there in Florida was/is biting his nails to correct this injustice. Basically, the defense is going to argue that a state court found her not guilty, why should she be guilty now? And can you imagine the jury selection for this too?
Of course, someone can also bring a wrongful death lawsuit against her, but that is civil, so she won’t be doing any time.
