Luis Alfredo Garavito Cubillos (born January 25, 1957), also known as La Bestia ("The Beast") or Tribilín (named after the Disney character "Goofy") is a Colombian rapist and serial killer. In 1999, he admitted to the rape, torture and murder of 138 children 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 here as ''the Monster of the Andes,'' as the largest-scale serial killer of modern times; however, in terms of the number of confirmed victims Garavito tops the list followed by López. The judicial body ruled that all Garavito's sentences total 1,853 years and nine days in jail.
