wow. you surely have quite an imagination. theorizing and explaining at great length for every single news you hear.
they may be in Mexico because he was in Mexican gang.
they may be in Canada because he had a military training.
they may be in Pennsylvania because he grew up in there.
let's calm down, Mr. Expert P.I. let's stick with news, shall we? I don't really care if you hopscotched back and forth between USA-Canadian border. I don't care how easy it is to get into Canadian border. I don't care at all because you did not escape from the prison and walked 10+ miles to the border as a prison escapee. it's not easy and it does not take 7 hours to get unless they're in excellent shape with excellent marathon-like endurance with outstanding sense of homing beacon and no supply at all.
