Luis Garavito

Luis Alfredo Garavito Cubillos, also known as La Bestia or Tribilín is a Colombian rapist and serial killer. In 1999, he admitted to the rape, torture and murder of 138 boys and teenagers. His victims, based on the locations of skeletons listed on maps that Garavito drew in prison, could exceed 300; Garavito continues to confess to more murders. He has been described by local media as "the world's worst serial killer." The Guinness Book of World Records lists another Colombian, Pedro Alonso López, known in Colombia as ''the Monster of the Andes,'' as the largest-scale serial killer of modern times; however, in terms of the number of murder convictions, Harold Shipman tops the list followed by Garavito, with López third. The judicial body ruled that all Garavito's sentences total 1,853 years and nine days in jail.
