I personally think we underestimate the younger generation. In many things they are more switched on than the older generation. I would argue that the older generation is careless with didgital footprints etc because the importance is a newish concept to us and are we are in the process of learning how importantant it is. Where as the younger generation were brought up with it and in many circumstances know more than we or should I say most of us do. Yes we are all experienced in life etc but there are so many things the younger generation is naturally more aware of than those older. Technology is one of them.

This is not what I meant, but thank you for this post because it gives some food for thought.
Version A. He is a (budding) SK, from Delphi or not, and A@L are random victims. Then he probably left his cellphone...somewhere, far from the bridge, put on this masquerade attire, drove to Delphi and was walking around in anticipation of the meeting.
Version B. A@L were targeted. Then he probably arranged the meeting before, and did not take the phone with him - but as the girls’ trip was arranged at the last moment, he can not live too far from the bridge, can he?
Version C. About that Snapchat photo. If indeed he was attracted by it, he lives somewhere very close by, possibly in one of the houses above the bridge, as to see the photo...he either have to have the cellphone on him, but then there would be a digital trace of it being in the proximity of Libby’s one, or, he has to see the photo, get into the clothes, leave the phone at home and walk to the bridge. So, home is close.
MOO. I assume there is no digital trace, so to me it would appear, that either BG is totally random (I personally don’t believe it), or he lives very close to the bridge.
ETA: if they are concerned about the car parked at the CPS building, supposedly it was his car and he left the phone in the car, it should still have pinged somewhere close to the building? Or it could have been on him? If it was neither on him nor in the car, it might by itself be suspicious as who is driving without cellphones these days? If only for GPS...
