Camargo was a Colombian serial killer who is believed to have raped and killed over 150 young girls in Colombia and Ecuador during the 1970s and 1980s. He calmly confessed to killing 71 girls in Ecuador after escaping from the Colombian prison. He led authorities to the dumping grounds of those victims whose bodies had not yet been recovered. After raping his victims, he had hacked the girls with a machete. He was convicted in 1989 and sentenced to just 16 years in prison, the maximum sentence available in Ecuador. In November 1994, he was murdered in prison by the cousin of one of his victims.
