Erasmo Moena

In 2007, he raped a woman in Múlchen, for which he was sentenced to three years and one day imprisonment. Moena was released on March 14, 2010, but only four days later, he sexually assaulted a 10-year-old minor at a bus terminal in Los Ángeles. Six days later, he raped another woman and on March 25, he committed his final rape on a homeless woman living on the outskirts of the city. He was identified as the perpetrator of these crimes, and local authorities issued a warrant for his arrest on April 1.

Moena then moved to Coelemu, where he quickly became friends with 27-year-old hairdresser Marco Antonio Cortés, who soon moved in with him. A close friend of Cortés claimed that the two men were in an intimate relationship, but Moena has denied those claims. On August 27, 1991, Moena murdered Cortés and, together with a group of friends, dismembered his body, set it on fire with gasoline and then threw the remains into the Itata River. He later admitted to the crime to a partner he had in Quirihue, who then turned him in to the police. Although Moena admitted to murdering Cortés, his remains were never found and he was thus acquitted of all charges. The motive for the murder remains unknown.

In 1990, the 20-year-old committed his first serious crime after robbing the "Provisiones Joaquín" warehouse in Múlchen. He was ordered to serve 541 days in jail, but since it was his first offense, the punishment was remitted.

Moena enrolled in the Margarita Naseau School in Tomé and later the San Pedro Nolasco School in Concepción, which he attended from 1983 to 1984. During the second semester of 1984, he was found guilty of several robberies and was summarily expelled. The most notable part of his school life that at one point Moena had to be hospitalized for a week for cranial injuries, as he had thrown himself off a moving bus and hit his head against the pavement as part of a game played by him and his friends. Reportedly, in his first and fourth year, he was classmates with future journalist and television presenter Julio César Rodríguez [es; simple].
