Yes, well, if this child died as a result of ongoing abuse or a recent act of abuse which I think is very possible, then they would both be accountable, as well as CPS, who had legal custody of the children. They were ultimately responsible for their safety and well- being.
I don't know how DV managed to hide the car or move it to its final location. It's hard to say whether or not he was truthful with his family or asked them to help. Since they believe his story, I'm thinking they didn't know.
But someone had to drop him off at the hospital. BB was at the airport, so it's questionable whether or not she had the time to drive to the hospital or not. That all depends on what time her flight came in, which LE had to have known very early on. I would think if they knew she dropped him off it would have implicated her in the crime and they would have charged her with something by now.
It would be interesting to find out at what point she went back to talk to them, if at all, and what those interviews have revealed to LE.
I really wish we would have an update soon, and this isn't one of those cases where there will be another arrest, and then a gag order is issued and we never hear anything else until it goes to trial.
But with all the people doing interviews that's probably exactly what they will do. Too many people have run their mouths already. Imo
