A3522F N313CG
This one appeared today (again). This is an ATR-42 operated by the US Drug Enforcement Agency. Based on comparing the news and appearances of this aircraft, I'm pretty sure this is an extradition airplane.
In a policy that's controversial for a variety of complicated reasons, the Colombian government often prefers to extradite alleged drug dealers, especially those of a right wing political persuasion, rather than prosecute them at home.
This ATR-42 seems to be the plane that they they get a free ride to Miami on!
