MEXICO CITY (AP) — Mexican President Andres Manuel Lopez Obrador on Wednesday defended the 2013 ruling that freed one of the drug lords most wanted by U.S. authorities, even though Mexico’s Supreme Court later ruled it was a mistake. Rafael Caro Quintero walked free while serving a 40-year sentence for the torture-murder of U.S. Drug Enforcement Administration agent Enrique “Kiki” Camarena in 1985, and has since apparently resumed his role as violent drug trafficker. Caro Quintero is at the top of the DEA’s Most Wanted list, with a $20 million reward for his capture. Lopez Obrador said Wednesday the legal appeal that led to Caro Quintero’s release was “justified” because supposedly no verdict had been handed down against the drug lord after 27 years in jail. Lopez Obrador also depicted a later warrant for his re-arrest as an example of U.S. pressure.
