Pedro Alonso López, also known as The Monster of the Andes, is a Colombian serial killer, child rapist, and fugitive who murdered a minimum of 110 victims, mostly young women and girls, from 1969 to 1980 and claimed to have murdered over 300 victims across Colombia, Peru, and Ecuador. He was briefly captured by an Ayacuchoan indigenous tribe in Peru, but an American missionary convinced the tribe to hand him over to the authorities, who released López soon after. López was convicted of vehicle theft, murder, and rape and was sentenced to 16 years in prison in Ecuador, but he was released after 14 years and committed to a hospital in Colombia, where he was freed after one year. López is considered the second-worst serial killer of all time, after Luis Garavito.
