Hiya all, I have followed this terrible case from afar, and I hope it is solved soon.
What surprised me is that the man on the bridge actually followed them, and this made me wonder where he had come from. IMHO there is no point in hiding in the bushes waiting for someone to pass by ... you might wait in vain a long long time.
He must have come from somewhere, within a short time frame, because it all happened shortly after they got on the bridge, and he must have gone to somewhere and ppl may have seen him on the road, before or after.
If he came by car, did he leave the car and how did he get back?
So my question would be if they know about everyone who was on the road leading to the trail, and on the various roads from the trail (assuming that he left in a different direction)
