Camargo had a de facto union with a woman named Alcira and had two children with her. He fell in love with another woman, Esperanza (age 28), whom he planned to marry, but then found out that she was not a virgin. This became the root of Camargo's fixations. He and Esperanza formed an agreement that he would stay with her if she aided him in finding other virgin girls to have sex with. This began a period of their partnership in crime. Esperanza was Camargo's accomplice, luring young girls to an apartment under false pretenses and then drugging them with sodium seconal sleeping pills so that Camargo could rape them. Camargo committed five rapes in this way, but did not kill any of the girls. The fifth child that they abused in this way reported the crime, and both Camargo and Esperanza were arrested and taken to separate prisons. Camargo was convicted of sexual assault in Colombia on 10 April 1964.
