The "false positives" scandal was a series of murders in Colombia, part of the armed conflict in that country between the government and guerrilla forces of the FARC and the ELN. Members of the military and their civilian collaborators lured poor or mentally impaired civilians to remote parts of the country with offers of work, killed them, and presented them to authorities as guerrilleros killed in battle, in an effort to inflate body counts and receive promotions or other benefits. While Colombian investigative agencies have found cases as early as 1988, the peak of the phenomenon took place between 2006 and 2009, during the presidency of Álvaro Uribe Vélez.
