In light of Wiffin's testimony, it's worth pointing out the difficulties for the defendant's doco version. in summary KR claimed she waited in the vehicle for 10 mins or so and got frustrated when the defendant did not come back. She called and he did not answer. So she left. We know she arrives home at 12.36
IMO the defendant's version was likely based on a 12.41 arrival time. The significance of the 12.36 router connection seems to have been missed by both sides (Lally famously had to change his timeline).
Wiffin's evidence is that John remained in the vehicle for a time after 12.24, and stopped moving forever shortly after exiting the vehicle.
It's also clear KR had already left 34F before she called John for the first time.
I am also intrigued that AJ appeared to say that 'they' got out of the vehicle. Does Brennan have Lexus door opening data?
But in any case, it appears the claim that the defendant waited for the victim cannot be correct. She had to have left pretty much when John got out.
