The carnage was made worse by U.S. demand for Colombian cocaine, which funded illegal armed groups including Mancuso's United Defense Forces of Colombia, known as AUC. With me they extradited the truth, Mancuso told Colombian media shortly after his arrival in the U.S. in 2008. Mancuso's apparently solid legal standing hasn't stopped Colombian officials from demanding his arrest. With the U.S. order that he be sent to his father's native Italy, Colombian officials have launched a last-ditch lobbying effort. While extradition of Colombian drug lords has helped relieve pressure on the country's investigators, it's far rarer for Colombia to seek arrests beyond its borders.
