Aug. 13 (UPI) -- The U.S. Treasury Department on Wednesday sanctioned four Mexican nationals and 12 companies in Mexico linked to a "brutally violent" cartel involved in a timeshare fraud of resorts in Puerto Vallarta. The Treasury's Office of Foreign Assets Control said the Jalisco New Generation Cartel is a U.S.-designated Foreign Terrorist Organization "that is increasingly supplementing its drug trafficking proceeds with alternative revenue streams such as timeshare fraud and fuel theft."
