Infamous drug lord Rafael Caro Quintero, who was behind the killing of a U.S. DEA agent in 1985, was captured Friday by Mexican forces nearly a decade after walking out of a Mexican prison and returning to drug trafficking, according to the Mexican government’s national arrest registry. Caro Quintero remains under indictment in Los Angeles for the crime. Caro Quintero and co-defendants were indicted in May 1987 in Los Angeles federal court on conspiracy and racketeering charges related to the kidnapping, torture and murder in Mexico of U.S. Drug Enforcement Administration Agent Enrique "Kiki" Camarena. The brutal murder marked a low point in U.S.-Mexico relations. Caro Quintero, the former leader of the Guadalajara cartel, had since returned to drug trafficking and unleashed bloody turf battles in the northern Mexico border state of Sonora. President Andrés Manuel López Obrador has maintained that he is not interested in detaining drug lords and prefers to avoid violence.
