Calarca and other members of the FARC left Mexico on 17 April 2002 with Cuba or Venezuela as presumed destinations.

In 1998 FARC kidnapped a number of foreigners including four American bird watchers. The FARC claimed that these four hostages were spies involved in counter-insurgency operations aiding the Colombian military. The United States denied this as well as then president of Colombia Ernesto Samper. Calarca mediated in the issue and was an active spokesperson for the FARC. All four Americans were eventually freed.
