US targets three linked to top Mexican drug lord Jan 10 11:58 AM US/Eastern The US Treasury Department on Tuesday froze the assets of three lieutenants of notorious Mexican drug trafficker Joaquin "El Chapo" Guzman. The Treasury Department named Mexicans Oscar Alvarez Zepeda and Joel Valdez Benites as well as Colombia's Carlos Torres Hoyos as helping El Chapo -- or "Shorty" -- and his Sinaloa cartel. The two Mexicans are said to be his relatives. "Today marks the fourth time in the past year that (the Treasury's Office of Foreign Assets Control) has targeted and exposed the support structures of the organization let by Chapo Guzman, the world's most powerful drug trafficker," the department said.
