text: I found this on the IMDB message board about this movie.\n\n"The character of the killer was inspired by the true story of the serial killer with possibly the record amount of killings, Pedro Alonso Lopez, "El Monstruo de los Andes" (monster of the Andes), who raped and murdered between 310 - 500 girls between Peru, Ecuador, and Colombia. \n\nLopez, a Colombian, was once captured in Peru by the cops. The natives of a town approached him when he was suspiciously talking to a young girl. He was captured and tortured by the natives for several hours, and he was about to be burned alive when a protestant missionary saved him. The cops intervened at that point and arrested him, but they did not believe the reports of the natives, and deported him to Ecuador. \n\nThe discovery of a mass grave after a flood in Ambato, Ecuador, in 1980 quickly led to his arrest. A confession was extracted out of him by making a priest pretend that he was a fellow inmate and join him in his cell. In one day of talking Lopez calmly confessed to all his murders. He later led investigators to the gravesites of several of his victims (53 just in the first gravesite). He currently serves a life sentence in Ecuador. "
