Across Columbia, Peru, and Ecuador over a span of thirty years, Pedro Lopez abducted, sexually assaulted and killed over 300 young girls.Lopez endured an early life of violence, homelessness, and sexual assault, which ultimately led him to be arrested for car theft when he was 21 years old. His first two murders were not in fact children; he killed two fully grown men with a makeshift knife, who had apparently sexually assaulted Lopez while in prison.Upon his release, he turned his attention to little girls, luring them to remote areas and leaving their remains covered in newspaper or branches.
