No dog tracked and then lost Bryce's scent, at the lake. That keeps being repeated and I was also confused by this at first but Dragracerz cleared that up.
There have been numerous articles that have the mom quoted as stating they took a family portrait a day or two before he left on his road trip. That always struck me as odd, because if he was up there in the Chico area, how was that possible? So it looks like they went up to settle Bryce in and the very next day is when he stayed up all night on Adderall, then the next day he tried or did break up with his girlfriend, and that day he began his trip south. Hopefully I have that right.
I have no idea what happened to Bryce! But I tend to suspect he suffered disassociative fugue or a breakdown of some sort, accidentally or purposefully crashed his car and simply began wandering. I think some of the symptoms began up north and he began wandering down south, without a real purpose in mind, at that time. I fear he could have been reacting to internal stimuli during the trip, either from lack of sleep, or organic causes, hence the long gaps in time during which he was circling or not driving.
Then, when he wandered away from the crash, I suspect he saw a trucker and stuck his thumb out. I don't think someone was there to meet him. I never bought into what seem to me to be complex drug underworld theories or secret plans to disappear with the help of a shadowy third party.
No reason for him to go all the way to tiny Buttonwillow or isolated Castaic to engage in nefarious activities, for example. And where was the time to do that if that was the plan? He starts school but has a plan to suddenly engage in drug trafficking or something, 200 miles away, during the school session, and LE finds no trace of anything in his vehicle? It doesn't make sense to me.
As far as having a concerted, well thought out plan to disappear, meeting someone who was helping him, etc., his behavior in the days beforehand and during the trip, his mom and girlfriend's behavior/reactions, and the overall circumstances just don't seem to point to that to me. (Phone records, computer records or the lack thereof, the timing, etc.). I sense much more impulse and instability involved in this disappearance.
I suspect he wandered impulsively away from the crash site much like he wandered impulsively away from college, and someone picked him up and either has no idea he is missing, because frankly, this story is only big to us, a few others on FB and to those who love Bryce, or the person is too scared to speak up because, if it was a trucker, for example, they are not allowed to carry hitch hikers and the person may think they could lose their job.
That's my best guess but my guess is no better than anyone else's.
If it was planned, is it possible it wasn't planned with a rational mindset?
