There didn’t need to be a call about changing the meet up place.
If Veronica and Jilian were headed for the Four Corners, they would have left Hwy 56 (which looks to me what road they’d have been on since leaving Hugoton) and gotten on 95 south just outside of Elkhart. That is the most direct way to the Four Corners spot; in my opinion, they were right where they should have been to get where they were going.
If you look at the map, what appears to be Four Corners is at the junction of 95 and the east-west Hwy 412, which looks like a much more well-traveled road.
The spot where the car was found, and that
@OldCop has marked on his map—95 and Road L—is one of the few spots between Elkhart and Hwy 412 where a person they expected to meet at Hwy 412/Four Corners could have been waiting, maybe flagged them down or set up an ambush.
The spot is south, past the school, and north of the next set of buildings where there might be people around.
Every day is too long without information.
