How about passport?
Where is BL? Million dollar question. The FBI knows so much more than all of us could possibly imagine at this point.
If I were in FL and I had a four day headstart to disappear myself before the Law could catch up with me there is only one place I could possibly think to go. Cuba. Forgive me if this has already been suggested. I haven't read even half the posts in the last 24 hours.
Yes, they are spending tremendous resources searching for him in the FL wilderness. They must have a very good reason to be doing that. The only reason I can think of BL going there is to die. Pick your poison.
But if I wanted to live, I would have begged, borrowed, stole, sold drugs, and done whatever it took to get as much cash as quickly as possible. Make my way to the FL Keys (camping trip with mom and dad?), hire some unsuspecting poor boat owner (there are a lot of poor boat owners living on their boats in the Keys) and pay them a nice chunk of change to sail me 90 miles. Now would that boat owner talk? There are a bunch of secrets in the Keys and the boat owner would be knee deep in Federal legal kimchi over their little boat trip.
Cuba loves American "tourists" AND dollars. He was not yet on the worldwide radar. Visa on arrival by boat. Take a bus to the middle of nowhere to a small town and go incognito till its time to grab a bus to another small town and rent another room from a poor family that is thrilled to have a dollar spending American.
We are not exactly as a country on the best of terms with Cuba right now so it is unlikely they would put out an isla wide APB for a Norte Americano. He would not be the first fugitive from US justice to make Cuba his/her home.
