Carlos Lehder, Medellín Cartel boss and Pablo Escobar's partner, freed in Colombia 3 days after arrest

Colombian authorities released former Medellin Cartel boss Carlos Lehder on Monday after a judge ruled that a drug trafficking sentence issued in Colombia against the 75-year-old had expired.

Lehder, one of the original "cocaine cowboys" and Pablo Escobar's crime partner, was arrested Friday night shortly after he landed in Bogota's airport on a flight from Germany, with immigration officials saying he was still wanted in the South American country on drug trafficking charges and weapons smuggling.

Lehder became the first Colombian drug trafficker extradited to the United States after he was arrested during a party at his ranch.
