The Zetas Vieja Escuela (English: Old School Zetas) is a Mexican criminal organization that splintered from Los Zetas.[1] It was founded by José Guizar Valencia, alias "Z-43", along with other dissidents of the original organization. The group took the name Vieja Escuela, arguing that they would continue the "original business" of drug trafficking, including the same brutality.[2][3]
