MAR DEL PLATA.- Two different paths in the judicial dynamics marked dissimilar destinies in the fate of two accused of a crime: The person who inflicted the fatal stab wound and faced a trial before a technical court received a sentence of 25 years in prison for aggravated homicide, while his life partner, who was at his side at the time of the murder, chose to face a popular jury and since last week has been serving a life prison sentence..
Julio César Bibbó and Marilyn Brisa Vera González They heard their sentences six days apart. According to the evidence obtained in the investigation, both participated in the attack and murder of Martín Mora Negretti, committed during the early hours of June 19, 2022 in front of a shopping center from the Old Terminal area.
From the evidence collected in this judicial process it emerged that Bibbó was the one who delivered the fatal stab wound to Mora Negretti and another that caused minor injuries to Bruno Valle, a friend who accompanied the victim. Their respective partners were eyewitnesses to the crime.
Those convicted today committed the act accompanied by two minors aged 13 and 14 who would have been part of a “prank” that shortly after unleashed this deadly outcome: the teenagers threw ice cubes from a high-rise apartment and bothered Negretti and those who accompanied him. They complained loudly from the street, where they were waiting for a taxi. Bibbó, Vera González and the two minors came down, knife in hand, and caused the tragedy.
The teenagers were considered unimpeachable and were excluded from the prosecution. Luis Mora Negretti, Martín’s father, then began a crusade to lower the age of imputability. He gathered signatures, encouraged a project and last month had the response of the approval of a new law that as of September, when it comes into force, allows prosecutions and sentences from the age of 14.
“I came with one hope: one more life. I don’t understand why a co-author rating is reached when he was the author of the act,” stated the victim’s father after hearing the ruling and regretting that the sentence was lower than what he expected.
“I think my son, at least, will feel the satisfaction that I tried to do justice by all means and fought until the last second,” he said, very moved. And he recalled that he had promised him two objectives before his grave: that the perpetrators of the murder would be tried and convicted and that a law would be passed that would lower the age of imputability. “Today I am calm”he assured.
The judges Roberto Falcone, Alexis Simaz and Federico Wacker Schroderwho make up the Oral Criminal Court (TOC) No. 2, understood that Bibbó was co-author of the crime of aggravated homicide due to the intervention of minors under 18 years of age and also attempted, for the injuries to Mora Negretti’s friend.
The prosecution had demanded a sentence of 40 years in prison and the complaint requested in its argument that he be sentenced to life imprisonment. The defense argued for a charge of simple homicide and minor injuries.

Valle, who accompanied Mora Negretti and survived the attack, testified during the trial and recalled that Bibbó went towards them with two knives that he “dragged against the floor.”
“Come on, I’ll kill you! What’s wrong with my wife?!”he shouted. The two young women who accompanied the victims also gave matching stories in the debate.
In their foundations, the judges particularly highlighted the testimony of a forensic psychiatrist who defined Bibbó as “an impulse machine” and they outlined a health history plus a maturation delay that would affect their performance and reactions. They also ruled out that there had been treachery and premeditated collaboration of two or more people.
Vera González, who was Bibbó’s partner at the time of the crime, came to the jury trial on the recommendation of her defense. Her situation seemed somewhat more alleviated given that no witness had seen her hold the weapon in an attack, although she did have it in her hands, according to witnesses and it could even be seen in security camera records, specifically, that of the building from which they had come down and where they lived, to which after the crime each one returned with a knife in hand.
The debate took place at the end of March and was resolved last Tuesday. The popular jury found her guilty of the crime of homicide aggravated by treachery and there the judge in charge, Fabián Riquert, informed her that her sentence was life imprisonment.
