Diego Alfonso Navarrete Beltran pleaded guilty today in US District Court in Washington to three counts of hostage-taking, which carries a maximum sentence of life in prison.
The FARC is Colombia's main rebel movement, formed in 1964 as the armed wing of the Colombian Communist Party. US authorities say it evolved into a major armed force financed by drug trafficking, hostage-taking and extortion. It has been on the State Department's list of foreign terrorist organizations since 1997.
Two others aboard the plane, American contractor Thomas Janis and Colombian army Sgt Luis Alcides Cruz were killed by FARC rebels at the crash site.
US authorities say Beltran, 43, guarded the hostages, who were often chained together and led on forced marches through the Colombian jungle. They were held in cages, left outside to face the elements and received no medical attention as their physical conditions deteriorated.
Two other FARC members were previously convicted for their roles in the hostage-taking. FARC commander Alexander Beltran Herrera was sentenced to 27 years in prison.
