One problem with assessing this case as it progresses is that this forum knows so much that has had no appearance in this trial. The testimony in either of the Idaho trials doesn't mean anything in this one. For this jury, and its verdict, if it hasn't been said here, it didn't happen.
So while LVD's behavior after the shooting is odd or inexplicable, on its face, I'm not sure it has actually told us that she knew in advance, and planned in advance, that CV would get shot and killed.
Even if she wanted him gone, even if she was glad he was gone, even if she danced on his grave (so to speak) after it happened, it doesn't prove she had anything to do with him getting killed.
If we have seen anything IN THIS TRIAL'S TESTIMONY that shows LVD knew and somehow planned with AC, in advance, I've missed it. Of course the testimony isn't over yet, so maybe that's still ahead, but I'm still waiting for that smoking gun.
ETA -- While it's a necessary part of the state's case to prove, the idea that AC didn't act in self defense merely shows that AC was guilty. It wouldn't prove anything at all about LVD being a part of it imo.
