In this 2008 photo provided by the U.S. Attorney's Office for the Eastern District of New York, Jesus Zambada is shown. Once a top lieutenant in drug lord Joaquin "El Chapo" Guzman's cartel, Zambada is now a cooperating witness describing the Sinolao cartel's history of greed, cunning and violence as it built a cocaine-smuggling empire that made billions of dollars by flooding the market in large U.S. cities.
