"The Colombian serial killer Pedro Alonso Lopez, who is known as the Monster of the Andes, raped and murdered over 300 girls from Ecuador, Peru and Colombia. However, after he was caught and imprisoned for 18 years, he was put in a psychiatric hospital. There he was reviewed, declared to be sane and was set free, in spite of his blatant avowal that he fully intends to kill again. Since he was released in 1998, nobody knows where he is or what he’s doing. ( He is supposed to be 71 years old at present).He is known for being the most prolific killer ever."
