Tomás Medina Caracas

He gained notoriety during the FARC-Government peace process (1999-2002) acting as a negotiator. He was also known for being the associate of Brazilian drug dealer Fernandinho Beiramar and for participating in an illegal arms deal of 10,000 AK-47s for the FARC through the Peruvian government official Vladimiro Montesinos, an adviser of former president of Peru, Alberto Fujimori. Medina Caracas was killed on 1 September 2007 in a Colombian Army military operation in eastern Colombia within the municipality of Cumaribo near the border with Venezuela.

Medina Caracas was of negroid origin. He became a teacher in a public school in the town of Santander de Quilichao, northern Cauca Department near the vereda known as Mary López where he was born. He later joined the FARC in May 1987 when he was 22 years old under the supervision of guerrilla leader Iván Márquez, a high-ranking member within the FARC chain of command. Apparently his nickname "Negro Acacio" was given by "Mono Jojoy" after one of the "heroes" of the Cuban Revolution.

Tomás Medina Caracas also known as Tomás Molina Caracas and Negro Acacio (15 March 1965 – 1 September 2007) was a Colombian guerrilla member of the Revolutionary Armed Forces of Colombia (FARC) considered by Colombian authorities the man in charge of the illegal drug trade business and the head of the Eastern Bloc's 16th Front of this rebel group.
