Hernán Giraldo Serna (born August 16, 1948), also known as the "Lord of the Sierra", is the leader of the Colombian paramilitary organization Tayrona Resistance Block, a 1,166-member armed group, part of the United Self-Defense Forces of Colombia.
He is also suspected in the murder of two narcotics agents and in the killings of Kankuamo Indians as part of his war against Marxist rebels, and the abduction of Colombian senator Jose Gnecco.
There are also outstanding warrants for his arrest in the United States for his role in the cocaine trade, but it is expected that part of his peace deal includes an implicit no-extradition pledge, as long as he doesn't violate any of agreement's terms.
[7] He was released from US Federal Prison on 4 January 2021, the Colombian Government immediately called for his extradition back to Colombia to face outstanding charges related to his time as a paramilitary leader.
Called El Taladro ("the drill"), some of Giraldo’s victims fear he will regain control of the Sierra Nevada de Santa Marta now that he is back in Colombia.
