Is it al-Qaeda's new boss Ayman al-Zawahiri?
A terrorist in Yemen?
Nope, it's Joaquín Archivaldo Guzmán Loera; Mexico's most prominent and richest drug lord nicknamed "El Chapo" or "Shorty".
This is a guy who escaped prison in 2001 and has evaded capture for 10 years - building a billion dollar international criminal empire that is largely funded by meth and the sale of cocaine all over the globe.
His continued freedom and incredible power, Forbes puts him as more powerful than the Mexican President, means that questions have been raised as to whether he's been given a carte blanche by the government or at the very least a few prying eyes have been turned away from his operations.
So the question today is whether you can stay the world's most wanted man without government support? Can it really be that hard to find someone if someone is really trying?
