Mexican police had been searching for Valdez since his 2002 indictment on two counts of conspiracy with intent to distribute
marijuana. In their investigation, police raided homes that he had rented, locating
grenades,
automatic weapons and police uniforms. In May 2009 Mexican authorities listed him as one of their 24 most wanted drug traffickers, and posted a 30-million-peso (US$2.3 million) reward for information leading to his capture. Valdez pleaded not guilty and took out advertising in the local Monterrey newspaper,
El Norte, describing himself as: "a legitimate businessman who had been forced to leave Nuevo Laredo and move to the neighboring state of
Coahuila because he was being harassed for bribes by local police officers." In June 2010 Valdez was indicted in a US court on charges of trafficking thousands of kilograms of cocaine from Mexico into the US between 2004-06. Mexican officials claim that Valdez introduced to the US about one ton of cocaine per month. In 2009 the
Justice Department posted a $2 million reward for information leading to his capture. ==Arrest==
