I can't tell if DG is super arrogant or a coward who crumbles when someone says 'boo'. I thought arrogant, but maybe I'm wrong. If we knew this I think it would help find where the trio were put and how.
I watched a recent episode of 'The Hunt' with Adam Walsh where they profiled killer Brad Bishop who murdered his 5 family members (wife, mother and 3 children) and is still a wanted fugitive. After he murdered them, he loaded them all in the back of the family station wagon and drove 275 miles (6 hours) with a car full of deceased persons to secluded woods, buried them in a shallow grave, poured gasoline and lit them on fire. My point is - Brad Bishop was arrogant enough to (take his time) and drive 6 hours with his deceased family in the car without worrying about the risk of being caught, then drew attention to the crime by the fire. I can't tell if DG would've spent the time to hide the family, or did he do a quick rid of them?
