context_section_description: Andrés Castillo was characterized by profilers as a psychopath and a classic sexual sadist. It is known that Castillo was the victim of repeated sexual abuse during his childhood, and in the opinion Nicolás González, the fact that all his victims were male and the way in which he committed the murders is a sign of the "emotional charge" of the abuses performed on him. According to the hypothesis of the criminal profilers, Andrés would've relieved the sexual abuses he experienced by switching roles, where he was no longer the helpless victim but the perpetrator with absolute power.
  Within the modus operandi of the "Chihuahua Ripper", it highlights his obsessive behaviors as the fact that he used the same coping saw in each of the homicides and especially the ritualistic behavior of leaving toys next to the bodies, according to a hypothesis of the specialists of the prosecutor's office these toys represented "the gifts that he could've received as a child", apparently projecting himself as he was a child to his victims, culturally with the toys being a common ofrenda for a dead child.
