Kiwi banker reveals his part in Mexico's drug war

A Kiwi-born banker has revealed chilling details of his undercover life working for vicious South American drug cartels, including watching a hit squad execute and dismember a group of people in front of him.

Keith Bulfin grew up in the small Otago gold-rush town of Lawrence. But years later he found himself working in Mexico City at the front end of the war on drugs.

He claims he was approached by the US Drug Enforcement Agency after striking up friendships with Mexican cartel bankers while in jail for conspiring to defraud.
