So why go through the trouble to crash the truck over an embankment to get yourself injured, break out the back window and leave your cell phone, wallet, cash, ID, laptop, duffle bag? Why not just park the car in a parking lot somewhere and take flight? Going on two years missing no contact whatsoever. Maybe he ended up overdosing somewhere with some druggies he met in Buttonwillow or around Castaic and they dumped him somewhere. I doubt they would drive him to the hospital. Buttonwillow is bad news.
