(Compass) – The Revolutionary Armed Forces of Colombia (FARC) freed evangelical government worker Luis Carlos Herrera on June 23, more than three months after they snatched him from a community center near the town of Caicedo . Herrera, 56, kidnapped March 17 along with Christian agronomist Ahimer Velasquez, was released after the Antioquia state government agreed to launch a development project in a FARC-controlled area. During his captivity, Herrera marched almost constantly with his guerrilla captors in mountain and jungle territory, sleeping in abandoned houses, in tents or in the open air. Herrera said that he is in good physical health, “but mentally, bad; psychologically very affected, and very sad for the situation in Colombia .”
