After catching up on this thread, I have a few random thoughts. Please correct me if I have the timing wrong or if my logic is off.
If we assume that the "last time" AJ was seen is 7:00 a.m Monday, and WH's work truck turned into the driveway of the house where she was found "around the time" she was last seen, this was a very quick abduction. That's even allowing several hours for "around the time."
AJ died from an overdose (however administered). Ending up at that house so quickly tells me WH intended to kill her. This wasn't recreational use that went wrong and he had to figure something out on the fly. If it all went down this quickly, it seems that he went to JH's house, took AJ, injected her, drove to NC, turned around and dumped her either dead or dying at the house in Franklin. Or he took her to that house, injected her and left.
Or he secured her alive at the house for his own use, and returned later and she died of an OD...? Have we ever considered this scenario?
But why? What happened that drove him to do this to AJ? Drug-fueled revenge on JH? Rejection by AJ?
On the other hand, if the time she was "last seen" is later than 7:00 a.m., by someone we don't know about yet, in a place we don't know about yet, that could perhaps change the scenario completely into an accidental, recreational OD covered up by WH. I doubt that, but we don't know for sure. It could still be deliberate.
I'm also a little hung up on the words "around the time" as that seems closer than a several hour window to me.
