I don't think he can possibly be on the road at this point. If I wanted to hide out somewhere near where I live I can think of a few places that I could hide for hours or days where no one could find me. This thing may go on until he is forced to search for food and water. I wonder if they took any supplies from the 7-11?
I suspect (no pun intended) he'll be caught within a few hours. They appear to have had no plan, based on thinking they were anonymous (wrong) and resuming their normal activities, and when their photos were released, panicking and carjackig to try to escape. The yonger brother is the only one left and appears to have no real chance to get away.
