The psychological profile of Máximo Thomsen, the most compromised

“It is a serious narcissistic disorder, where what prevails is the discharge of aggressive impulses, not reflection,” explains the expert psychologist Alejandro Farji. “It is a group that shows a certain superiority over the law”, understands the psychologist Irene Sirianni. An approximation to the head of a clan that “moved” with a “feeling of impunity”.

He is seen kicking Fernando Báez Sosa (18). He is seen walking away from his victim with his dark shirt open. He sees him running off to change his clothes. Before, he was seen leaving the Villa Gesell bowling alley between two patovicas who found it difficult to control him. Multiple witnesses saw him hit the victim and one of them said that he did it “with the intent to kill.” Later he went to eat at a fast food house and it was even him, the one who involved an innocent man in the act. The different experts located him in the videos analyzed and even the shoe print that was imprinted on the jaw of the murdered young law student bears his name. He sees it and mentions it everywhere.

The scientific and testimonial evidence corners Máximo Thomsen (23), as well as his seven friends who surrounded Fernando three years ago at the exit of the Le Brique nightclub to beat him to death, according to the theory maintained by the prosecution and the victim’s family.


Thomsen is, of the eight defendants, the most mentioned during the ten hearings that have been held so far in the Dolores Courts for Fernando’s crime. But, how can his actions be analyzed from the psychological profile, an expertise to which none of the defendants submitted during the trial on the advice of the defense?

Psychologists consulted by Perfil agree that it presents “traits compatible with psychopathy”, which has the characteristics of “imposing yourself on another”, “not feeling guilty” and “standing out from the rest” at any cost, among other peculiarities.

“The psychopath has certain behavioral characteristics that make this type of crime possible. Since there were and will be people who fight at the exit of a nightclub, but not stopping your behavior when the person is lying on the bloody floor is a very strong indicator of contempt for human life”, explains Irene, a graduate in psychology. Sirianni, who works as an expert witness in the National Judiciary.

For his part, the expert psychologist and forensic clinician Alejandro Farji understands that “the picture that arises from the defendants is psychopathy, a picture that does not appear to be a mental disorder, but is one of the most serious.” And he clarifies: “so serious that it cannot be cured due to its characteristics, namely: there is no awareness of the disease, that is, they do not suffer from symptoms, they become character traits and are egosyntonic; there is no feeling of guilt, therefore there is no need for punishment; It is a serious narcissistic disorder, where what prevails is the discharge of aggressive impulses, not reflection”.

Are you born like this? “No, it builds in the family structure with an omnipotent father that builds his own law. And the results are on sight. In three years there was no regret from either the parents or the children, ”he says. In this line, Sirianni highlights that “it is a group that shows a certain superiority over the law” and exemplifies: “If a patovica tells me that I cannot enter the VIP, it is not necessary for him to struggle with me so that I do not enter because I understand the authority, I understand that he is giving me an indication and I comply with it. But if I had Thomsen’s head, I would plant myself against the security man because I would consider that he is nobody to throw me out, I perceive that he has no authority to tell me what I have to do ”.


“The psychopathic profile is in this special need to stand out from the rest, to impose itself on the other by hook or by crook. The psychopath has this special need to do special things, as the leader of a group that does different things”, details Sirianni and clarifies: “blaming another for an action that I clearly did is psychopathic. It is putting the guilt outside. The feeling of superiority and impunity with which he operated is also based on not perceiving the other as a peer, as a human being, but as an object to fulfill a goal, which in this case was to demonstrate his effectiveness as a leader and the imposition on another of his own laws.

Whose shoe is this? That was one of the questions that one of the police officers asked when they went to arrest the defendants in the house they rented in Villa Gesell that January 18, 2020. Thomsen replied that they belonged to Pablo Ventura, a young man from the Buenos Aires town of Zárate, where they all come from, but that he was completely oblivious to the fact and that, while the defendants surrounded and attacked Fernando, he was kilometers away.

That shoe was not from Ventura, but for the false accusation he was detained for three days. “The template that belongs to the citizen Máximo Thomsen corresponds to the print on the lower left jaw (of Fernando),” declared this week María Eugenia Cariac, a graduate in Criminalistics from the Scientific Police of the Province of Buenos Aires. It is that Fernando was attacked with such violence that the sole with a zigzag design was imprinted on the teenager’s face. In addition, it was confirmed that the blood found there corresponded to the victim.
