According to the experts appointed by the defense of Stasi, the imprint 33 – attributed to Semdio by the prosecutors – was left by a hand “smeared with sweat and blood material”. Thesis contested by the lawyers of the Poggi family, who consider the imprint that cannot be used for a comparison.
The imprint number 33 found on the wall of the stairs in the house in via Pascoli in Garlasco would have been left by a hand “smeared with sweat and blood material”. This is the conclusion (made known on the social networks of TG1) to which the defense consultants of Alberto Stasi – sentenced to 16 years for the murder of Chiara Poggi – in a new report delivered to the Pavia prosecutor’s office by the lawyers Giada Bocellari and Antonio De Rensis, arrived.
A technical advice that enters the direct contrast to the appraisals filed by the lawyers of the Poggi family and those of Andrea Semovernow investigated as possible responsible for the crime. According to the Defense Consultants Stasi – Oscar Ghizzoni, Pasquale Linarello and Ugo Ricci – the imprint 33, attributed by the magistrates to Semve, would not only be compatible with his hand, but but It would have been left by an “intense” and not accidental contact, which occurred with a hand contaminated by blood and sweat.
The technicians in charge have conducted a series of experiments on surfaces similar to those of the Scala della Casa di Chiara Poggi, using dirty hands of various substances – reports the Corriere della Sera. The results: to obtain a visible and clear imprint such as number 33, once the ninidrine has been applied (the reagent used to detect biological traces), It is necessary “an intense palm -breaking contact, certainly not superficial/elusive/stripped” and “is not compatible with a normal descent for the stairs”. According to the consultants, the point where the imprint was left indicates that “It may have been left by leaning out of the threshold (zero step) of the staircase leading to the cellar, given that it is the most natural position to exert the pressure found”.
Another key aspect raised by the defense of Stasi concerns the methods used by the Ris in 2007. According to consultants, lime and ninhydrin treatment would have “inhibited blood search tests”, making the Obti test ineffective in particular, normally used to identify blood tracks. The experimental tests would have confirmed that the reaction between plaster and reagent compromised the possibility of identifying the presence of blood with certainty.
The expert’s opinion is clear: “The technical-deactyloscopic analysis implemented on imprint no. 33, together with the experimental tests carried out on the wall with plaster under different conditions, allow you to believe that this imprint was smeared with sweat and blood materialgiven that only in this situation are the deposits of organic material found on the imprint no. 33 »
The prosecutor’s evaluation of the prosecutor’s office remains to wait, who entrusted specific technical advice to the Racis dei Carabinieri. The goal is twofold: verify the possible presence of blood and clarify the role of the imprint in the dynamics of the crime. In recent days, in response to a request by the lawyer Gian Luigi Tizzoni (lawyer of the Poggi family), the assistant prosecutor Stefano Civardi confirmed that the plaster sample was not found picked in 2007 during the reliefs of the Ris. An absence that makes “further biological investigations” not possible.
Despite this limit, The prosecutor led by Fabio Napoleon is working to reconstruct the context of the imprint, Based on a report signed by the expert of the Ris Gianpaolo Iuliano and the Dactyloscopist Nicola Caprioli. According to their analysis, The track, initially deemed unusable As partly partially visible (5-6 minutiae), it would instead be superimposed in 15 points at the PDA track by Andrea Semplio.
A thesis rejected by his lawyers, Angela Taccia and Massimo Lovatisupported by two exceptional consultants: Luciano Garofano, the former Ris commander who dealt with the investigations at the time, and Luigi Need. Their position is clear: The track would contain only five valid minutiae and the conclusions of the prosecutor’s experts would be spoiled by a methodological errorthat is, having confused signs of the plaster with characteristics of the actual imprint.
The Consultants of the Poggi family also of the same noticeDario Redaelli and Calogero Biondi, according to which the imprint 33 remains “not usable for a comparison” and, in any case, would be the result of A “fast” and “not bloody” contact.
The truth, almost twenty years after the crime, still seems buried under a often layer of uncertainties, technicalities and contrasts between experts. But the new analysis on imprint 33 could represent a decisive turning point.
