Victor Rivera
On April 8, 2008, Victor Rivera, a Venezuelan national, was shot and killed while driving in Guatemala City. Two days earlier he had been fired from his advisory position to the Ministry of the Interior, where he was investigating the deaths of the Salvadoran deputies. The murder of Rivera, in turn, was investigated by former Attorney General Álvaro Matus, who was himself accused of conducting a cover-up by prosecutors from the "Comisión Internacional Contra la Impunidad en Guatemala". Matus surrendered to authorities on February 3, 2009, but the charges against him were immediately dropped by the Public Ministry and he was released.
