Colombian Drug Lord Gets 16+ Years in US Prison A Colombian cocaine kingpin has been sentenced to more than 16 years in federal prison after pleading guilty to U.S. drug trafficking charges. A judge in Miami imposed the relatively lenient sentence Tuesday on 47-year-old Jaime Alberto Marin-Zamora, a former leader of Colombia's North Valley cartel. He had faced up to 24 years, but prosecutors recommended less because of his assistance in other cases.
