The victims were poor children, peasant children, or street children, between the ages of 6 and 16. Garavito approached them on the street or countryside and offered them gifts or small amounts of money. After gaining their trust, he took the children for a walk and when they got tired, he would take advantage of them. He then raped them, cut their throats, and usually dismembered their corpses. Most corpses showed signs of torture.
Garavito was captured on 22 April 1999. He confessed to murdering 140 children. However, he is still under investigation for the murder of 172 children in more than 59 counties in Colombia.
He was found guilty in 138 of the 172 cases; the others are ongoing. The sentences for these 138 cases add to 1,853 years and 9 days. Because of Colombian law restrictions, however, he cannot be imprisoned for more than 30 years. In addition, because he helped the authorities in finding the bodies, his sentence has been decreased to 22 years.
