Agustín Vásquez Mendoza is a Mexican citizen[1] who was sought for four years in the late 1990s[2] by the United States Federal Bureau of Investigation (FBI) as the 445th FBI Ten Most Wanted Fugitive for his alleged participation in a drug conspiracy which led to the death of a U.S. Drug Enforcement Administration (DEA) Special Agent.

DEA agents believe that Agustin Vasquez Mendoza was helped to go on the run by one family member with a sur-name Prado Vazquez, from Aguililla, Michoacán.

When the detectives questioned the alleged family, they refused to release a statement regarding Agustin Vazquez Mendoza's whereabouts.

[3] DEA Special Agent Richard E. Fass was murdered while acting, in an undercover capacity, as a buyer of methamphetamine from Vásquez.

In 2006, Mendoza was convicted of first degree murder in Arizona and sentenced to life in prison.
