Efraín Teodoro Torres (died 3 March 2007) was a Mexican suspected drug lord and one of the founders of Los Zetas, a criminal organization formed by former soldiers of the Mexican Armed Forces. He joined the Mexican Army in mid-1991 but deserted after seven years of service. In 1998, Torres was recruited by the drug lord Osiel Cárdenas Guillén to join the ranks of the Gulf Cartel, a drug trafficking organization. The new group formed by ex-commandos came to be known as Los Zetas.
