The casuistry deals with an aggressor with a long history of the combined consumption of toxic substances of cocaine and alcohol, who perpetrated the murder of a minor under 13 years of age. The victim was assaulted while she was going down the stairs of a block of flats and was taken, against her will, to the aggressor's home.
Regardless of the motive for the assault, the perpetrator restrained the victim, choked her with a dog leash until she asphixiated. Subsequently, he gave her multiple postmortem puncture wounds with a knife, one of which was a grave stab into the left ear (breaking the knife, with the blade remaining inside the auditory organ) and another wound in the left chest. In the autopsy, the introduction of a ballpoint pen into the minor's trachea was also appreciated.
The aggressor, who was evaluated directly by the writer, stated that, although aware of his conduct "because he was told a posteriori of the consequences of his actions", he maintained that he had no recollection of the alleged events.
Likewise, he stated that he was in a critical and/or adverse psychosocial situation due to the recent death of his mother and that, due to this, the pattern of use and abuse of toxic substances (cocaine and alcohol) had increased.
