re: US marshals lure fugitive killer of Texas cyclist out of hiding with yoga ad (bonus WYHI)

Two problems with immediately heading SE Asia. 1) Money, you might spend $3K or more trying to get a direct flight (can't risk a connection and another passport check) at the last minute, and unless you have cash on hand that could alert authorities, and 2) That's a lot of time in the air for the authorities to eventually track you.

I'm sure she was able to get a much cheaper same day flight to San Jose. Also, assuming they realize you are gone 12 hours after you board your flight, you can be halfway across the country in Costa Rica, or you could be on a plane.
