According to his mother, María Elizabeth Pinto Villegas, he suffered no physical or mental abuse while growing up, but was a poor student who was treated as an outcast by his peers due to his macho and hypersexual attitude.

[1] Reportedly, in his first and fourth year, he was classmates with future journalist and television presenter Julio César Rodríguez [es; simple].

[2] After school, Moena enrolled at the Universidad Técnica Federico Santa María in Concepción, where he studied mechanical engineering, but lasted only one semester.

[4] 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.

On April 6, Moena posted a listing for a supposed job offer in the newspaper and received a reply from 36-year-old Loreto López Fernández, the daughter of retired gendarmes.

[1] After some time had passed, a cousin of López named Nelly Andrea San Martín Fernández contacted Moena under the pretense of being interested in his "job offer".

[6] PDI investigators traced the phone call to Moena's identity card, and with San Martín's help, they organized a stake-out at a coffee shop near the bus terminal in Valparaíso, where the pair had agreed to meet up.

[9] While his trial was underway, Justice Isabel Uribe ordered that Moena remain in solitary confinement and under constant surveillance while the investigation took place.
