Raúl Hernández Barrón (4 February 1977 – 26 July 2014), also known by his alias Flanders 1, was a Mexican suspected drug lord and high-ranking member of Los Zetas, a criminal group based in Tamaulipas, Mexico. Hernández Barrón served in the Mexican Army from 1993 to 1999 as an infantry soldier. He then left and joined the Gulf Cartel under the kingpin Osiel Cárdenas Guillén, and became part of the first members of their newly formed paramilitary wing, Los Zetas. Like Hernández Barrón, most of the first members of Los Zetas were ex-military. Los Zetas was responsible for providing security services to Cárdenas Guillén and carrying out executions on the cartel's behalf. Hernández Barrón was also responsible for coordinating drug trafficking activities in Veracruz.
