What I think justice in this case looks like = CA, WA, DA, HA, all serving life, but that's not going to happen. The next best thing is all of them serving a decent amount of time and for that to happen, someone is going to have to make a deal. I think the State can be sneaky here and convince DA to make a deal. Sorry "deal". i.e she's looking at a life sentence, offer her 15, out in 10 and that for me isn't justice, but if it secures WA's conviction then its worth it and also that 10 years is probably going to be a life sentence for DA anyway. She'll be 83 by the time she's released, she already looks old and frail with health issues, jail won't be kind to her. If she makes it to 83 and is released, there won't be much of a life left for her.
I really want them to get something on HA and then use him as a pawn, offer him a deal. He's not going to want to do 20+ years in state prison for something that he probably thought was a bad idea and something that was carried out with complete and utter incompetence by all parties. There must be some anger and bitterness on his part. Their amazing life in Miami, ruined, just so his daughter can move cities with her kids. I don't care how much love and loyalty you have for a partner or a family member, they do something so cataclysmically stupid that ruins their life and yours, you're going to be pissed at them x 100. And you're certainly not going to spend your last days in prison because of their choices.
