The Test presented yesterday managed to generate lat first crack in the pact of silence that the rugbiers maintain in the trial for the crime of Fernando Báez Sosa. It is that, in the ninth hearing, the experts of the Federal police who analyzed videos and photos of the beating of the 18-year-old boy made an important multimedia contribution through which it was observed that Luciano Pertossi would have participated in the deadly attack to Ferdinand.

“I want to clarify something, shall I? I was not there”he said in the middle of the day —as detailed infobae— the first of the eight defendants to speak throughout the process. His words were recorded after the film of his face identification with the video in which a person with the same characteristics is observed being part of Fernando’s group of aggressors.

—The 181 is the specific image in which a person with similar characteristics is seen according to the clothing…

—Would Luciano Pertossi be “Subject 11V” in the image?

–Yes.

The statement was made to this medium by Laura Friendhead of the Criminal Individualization Division Facial Forensic Analysis of the Federal Police, who analyzed the work carried out by the area and the impact it generated. “Obviously we knew that Luciano Pertossi spoke and then he did not want to declare more. It’s like everything stayed there in the nebula: they had that pact of silence that maybe one to save themselves, reacted. That, perhaps, is positive for Justice”.

“With our work, what we seek is for this to be clarified: it is a fact that we all repudiate and we seek that this serve for a resolution. Also so that obviously discard all those who have nothing to do and those who correspond are detained. If this sheds light on a lot of points in the investigation, that’s what you try,” added Amigo.

Yanina Cuenca, Agostina Matticoli, Ricardo Gabriel Pisoli and Andrés Bruzzesemembers of the PFA specialized in facial analysis, were the ones who testified jointly before the Oral Criminal Court No. 1 on a day marked by the first words of one of the rugbiers.

“Here we have professionals specialized in criminalistics and facial forensic analysis that what they do is initially analyze the footage that are provided to determine the quality of these images and if they serve as a face to make a comparison, a comparison,” Amigo explained when addressing a job that, according to what he said, started in August 2020 and was presented two months later.

In this regard, he commented: “It was very urgent. It was a very relevant cause and we had to put other jobs aside to focus on this. It is a cause that demanded immediate resolution. The work team did it in an accelerated way, analyzing more than ten cameras with filming, with hours and hours of recording to obtain the reports on time. It then went on to be analyzed by the Justice as part of the evidence.

The head of the Criminal Individualization Division Facial Forensic Analysis tells that the prosecution was the one that sent them all the material. “Since then, this work began and it took time because it has to do with analyze, sequence and try to find where the cameras were located. For this reason we also add a Map to locate where the camera is installed and be able to see the follow-up in the sequence of images of a certain person,” he said.

“To translate it into sheets, we assign a letter or a number to the individuals: Subject 1, Subject 2, Subject 3 to all those who we observed in the place and who are linked to the event,” Amigo explained. Then, finally, the comparison is made with the indubitable material and then the comparison, as can be seen at the end of the work: the relationship for clothing, which is the last thing that the prosecution also requested of us. At this point, he emphasized: “We see the correlation of clothing if the face cannot be observed.”

The quality of the audiovisual material also influenced the research. “Not all the film sequences were apt to analyze the face and we also resorted to a comparison at the level of physical build and clothing that could be linked”.

“For example, in principle we made the images of the indubitables, which were provided by the Technical Offices for Identification of Persons (OTIP) of Dolores, who extracted them voluntarily photographs to the defendants so that they can be compared with these events, ”explained Amigo. Regarding these photographs, the curator added: “In addition to the face, here you can see the physical build and that also allowed us to analyze the sequences precisely from the structures and physical contextures”.

In the event that the images do not clearly expose the faces, the analysis of the contexture or body structure helps identification. “Yes, it can be linked or dismissed. If it is not completely suitable, it is discarded. In this case, a succession was made from when we can see them more clearly at the exit of the dance hall, where you can see them; From there, the correlation and camera monitoring with those clothes were made to be able to link or rule out the specific event in which Fernando lost his life, ”revealed the commissioner.

In this regard, Amigo specified: “Our conclusions are sometimes ‘likely’. We talk about ‘probability’. This is provided in Justice and then the degree of significance that they are going to give to this type of report is determined.
