I agree here too, gut feeling, no facts, BUT SOLELY based on if the TTVid Hitchhike with Baker is TRUE, that this vicinity is the last known area and time that they were together. Note their last separation very well could have been day before 8/28. He may have used 12-24 hours to cover tracks, dispose, travel etc.. back to where he was picked up. BR does not come across to me as that smart at his age but I believe he may have carefully planned/pre-mediatated this beginning around the time they were pulled over by police in Moab. reasons for pre-meditated are unknown, could be numerous and many have been mentioned, pregnancy, etc...
