Pedro Alonso López (born 8 October 1948[1]) is a Colombian serial killer, who was sentenced for killing 80 girls, but who claims to have raped and killed more than 300 girls across his native country, then Peru and Ecuador, and possibly other countries. Aside from uncited local accounts, López's crimes first received international attention from an interview conducted by Ron Laytner, a longtime freelance photojournalist who reported interviewing López in his Ambato prison cell in 1980.

Laytner's interviews were widely published, first in the Chicago Tribune on Sunday, 13 July 1980, then in the Toronto Sun and The Sacramento Bee on 21 July 1980, and over the years in many other North American papers and foreign publications, including the National Enquirer. Apart from Laytner's account and two brief Associated Press wire reports,[2] the story was published in The World's Most Infamous Murders by Boar and Blundell,[3] and has found its way into many serial murder anthologies, both in print and on-line.

According to Laytner's story,[4] López became known as the "Monster of the Andes" in 1980, when he led police to 53 graves in Ecuador, the victims all girls around nine to twelve years old. In 1983, he was found guilty of the murder of 110 girls in Ecuador. He further confessed to an additional 240 murders in Peru and Colombia.

López was released from a psychiatric hospital in 1998 for good behaviour, after initially being found insane. His whereabouts are currently unknown.[5]

An A&E Biography documentary reports that he was released from an Ecuadorian prison on 31 August 1994, then rearrested an hour later as an illegal immigrant and handed over to Colombian authorities, who charged him with a 20-year-old murder. He was declared insane and held in the psychiatric wing of a Bogotá hospital. In 1998, he was declared sane and released on $50 bail, subject to certain conditions. He later absconded. The same documentary says that Interpol released an advisory for his rearrest by Colombian authorities over a fresh murder in 2002.

Currently there is mixed information of his whereabouts, one citation says he is in prison but does not state when and where he is incarcerated. Other articles referenced in the source/citations said his whereabouts are unknown (2017).


Lopez has been written about mainly in articles by Ron Laytner and in serial killer encyclopaedias. There was an English language documentary made by A&E better known as the Biography Channel.[citation needed]

Guinness World Records briefly credited Lopez as being the "most prolific serial killer".[6]

AP wire reports[edit]

Two Associated Press (AP) wire reports from July 1980 and January 1981 are extant.[2] The first is a late report of López's arrest in March, and his confession to killing 103 girls, including 53 whose bodies had been found. The second reports that he was convicted of three murders, and had confessed to three hundred sexual assaults and stranglings.[2]
