A former Mexican drug trafficker who once claimed he was a double agent for the Drug Enforcement Administration took center stage on Thursday against infamous kingpin Joaquin "El Chapo" Guzman at a U.S. trial. 

Nabbing the bad guys was only part of the challenge facing federal officials who shut down an illegal marijuana garden growing on U.S. rangeland in remote wilderness in northeast Nevada's Snake Mountains.

Humboldt County Sheriff Ed Kilgore is defending the practice of stopping suspected drug traffickers on U.S. Interstate 80 and confiscating tens of thousands of dollars even if no criminal charges are filed.
