My $0.02.
1. This is not a "traditional missing persons case."
2. As GP's dad said, "He's not missing, he is hiding."
3. BL got a good head start on LE before they even knew he was "missing."
4. BL most likely took food and money with him.
5. The food and money will run out soon.
6. BL's challenges will be 1) where to get more food and money, and 2) how to avoid being seen while accomplishing 1).
7. Unless he has a vehicle of some kind (where is his bike?), it would be difficult for him to go anywhere without being seen by someone. (Bus, train, hitchhiking are possible, but risky.)
8. It's only been a month since BL made a run for it. IMHO, not very long, considering his head start.
9. Not having a vehicle (that we know of) somewhat works in his favor, as there is no license plate to track.
10. Not having a vehicle (that we know of) somewhat works against him, as he will need to stay within walking (or biking, or delivery) distance of supplies.
ETA:
11. There's a price on his head.
That's all I have this morning. All JMHO.
