I think the shooting of CV was a planned ambush by LV and AxC and they created a narrative in advance to support an "it was done in self-defense" story that they believed would remove them from suspicion of criminality. They gave TR a starring role in that narrative by having her - a minor child (NOT either of the adults) be the one who first introduced a weapon (the bat) into the scene. IMO, they did that because they thought police would surely believe an innocent, scared teen, even if they had suspicions about the estranged wife and her brother (who'd previously criminally attacked his sister's ex-husband and had done time for the offense).
There were inconsistencies between the evidence and the various stories told by LVD, TR, and AxC about timing of who was there when the shots were fired and how many shots were fired. AxC's story had LVD and the kids leaving before the SHOTS (multiple) were fired; LVD's story had LVD seeing CV after the SHOT (singular) was fired. TR's story had TR going in to get LVD's purse after TR had heard a single loud noise. ETA: CV was shot twice in the chest.
There were things that just didn't make sense: why invite an estranged husband who you are telling police you believe to be mean, nasty, and occasionally violent to the home rather than meet at a neutral location; if he is so mean and potentially violent that you invite your brother to stay so he'll be on scene, why take his phone - HIS private property with HIS private communications - and provoke his anger; why continue to withhold his phone and further escalate his anger; once you flee the scene in HIS car with the two children for their safety, why not go to police; once you leave the home in HIS car and know that the situation has become intense and potentially violent and that your brother is still there, why not call police to the scene from the safety of the car; if the shooting has already occurred and you know someone's life is endangered, why not call for police PLUS emergency medical care?
Beyond those rational questions, how to explain that AxC feared he was in such imminent danger that he'd be beaten to death with him having the time to get himself to a separate room, collect his gun, and turn around and shoot CV multiple times in the chest? Did CV just stand there, twiddling his thumbs, and wait for AxC to do all that? Are we to believe that CV secured JJ and Bailey in the car, left it running, and then forgot he'd done so and that he had limited time to get JJ fed and off to school as he engaged in a dispute with LVD, AxC, and TR? The minor wounds on AxC's head sure don't attest to a serious attack. The care and concern CV generally showed for JJ don't support the idea that he'd advance an attack upon all of them while JJ and the dog are out there waiting to be taken to school. At most, CV went in to retrieve his phone and expected that to be a quick trip inside and back out again.
What we know from MG's recent interviews is that LVD is a crafty liar and she is perfectly capable of creating a narrative that is not true, but that paints herself as an innocent person when she is not, and that she will orchestrate events that involve others in her lie to support her created narrative. LVD did so with TR with the supposed bat that CV supposedly took away and wielded himself as a dangerous weapon on July 11, 2019. LVD attempted to do so again when she instructed MG to lie to police and to take photos of random children that MG was supposedly to have taken while out with JJ to see Frozen 2 in November 2019 (as LVD had lied to police that JJ was staying with MG and they were currently out seeing that movie).
ETA: CV didn't wield a bat. There was one planted nearby him after he was dead to support the created narrative. None of MG's photos (had she obeyed LVD's instructions to take them) would have featured JJ and we all know why.
