Juan Reyes Mejía-González (born 18 November 1975), commonly referred to by his alias R1, is a Mexican drug lord and high-ranking member in the Gulf Cartel who allegedly heads Los Rojos, a faction within the cartel. Mejía González was often accredited as the "second-in-command" in the Gulf organization. He is responsible for controlling the flow of cocaine from Central America and South America to the drug corridors between Nuevo Laredo and Reynosa, Tamaulipas. In March 2008, Mejía González was indicted in Washington, D.C. and placed as one of the most-wanted fugitives by the U.S. government.
