Garavito was captured on 22 April 1999. He confessed to murdering 140 children, and was charged with killing 172 altogether throughout Colombia.[4] He was found guilty on 139 of the 172 counts; the others are ongoing. Although the maximum sentence for murder in Colombia multiplied by 139 comes to 1,853 years and 9 days, Colombian law limits imprisonment to 40 years. Because he helped police find some bodies, as well as to his confessions, his sentence was further reduced to 22 years.[5] He may possibly qualify for even earlier release for further cooperation and good behavior.

López was arrested when an attempted abduction failed and he was trapped by market traders. He confessed to over three hundred murders. The police only believed him when a flash flood uncovered a mass grave containing many of his victims. According to the BBC: "He was arrested in 1980 but was freed by the government in Ecuador at the end of [1998]." In an interview from his prison cell, López described himself as "the man of the century" and said he was being released for "good behaviour".

An A&E Biography documentary reports that he was released by Ecuadorian prison on August 31, 1994, 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 found to be insane and held in a 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.
