MIAMI (AP) - A Colombian cocaine kingpin has pleaded guilty in Miami to U.S. trafficking charges months after rejecting the government's first proposed plea deal.
    
Jaime Alberto Marin-Zamora pleaded guilty Thursday to a single cocaine trafficking conspiracy charge. The 47-year-old best known as "Beto" Marin faces a required minimum 10-year sentence and could get more. Prosecutors say if Marin-Zamora continues to cooperate they will seek a more lenient sentence.
    
Marin-Zamora rejected the earlier plea deal because he could have gotten life behind bars.
    
Marin-Zamora admitted being a kingpin in Colombia's North Valley Cartel. He was arrested by Venezuelan authorities in September 2010 at a resort off the Venezuelan coast and brought to the U.S. soon after.
    
U.S. authorities had offered a $5 million reward for information leading to his arrest and conviction.
