The DNA on the pedals that could "exonerate Stasi 19 years ago"
And an unprecedented element also emerges in favor of Alberto Stasi. The genetic profile determined on 19 September 2007, writes Napoleone, "obtained from the bicycle pedals" and attributed at the time by the prosecutors' consultants to Chiara Poggi "had tested totally negative the following day", but of these "two electrophoretic runs" there was "no trace found in any document of the proceeding/trial held against Alberto Stasi". A fact discovered by the defense consultants to "exonerate" the former Bocconi student and which the technical consultants of the Pavia Prosecutor's Office "confirmed" by speaking of the "existence of the negative electrophoretic runs of 20 September 2007". Napoleone explains that "consultancy was acquired" from the experts Ugo Rici and Pasquale Linarello "nominated by Alberto Stasi's defence" with at its center "the Raw Data delivered to the Pavia Prosecutor's Office by the Parma Ris on 6.11.2025" as part of the recently concluded investigation into Sempio. In those "Raw Data" the two experts "detected the presence of counter-analysis (two electrophoretic runs dated 09.20.2007) of the bu_p sample (the same sample that revealed the presence of the victim's DNA on the pedals of Umberto Dei's bike and which led to Stasi's arrest) which were totally negative, counter-analysis suitable, in their opinion, to exonerate Alberto Stasi already 19 years ago, but not existing in the file" against the latter. In other words, writes the Pavia Prosecutor's Office, "the genetic profile determined just the day before (19.09.2007) from the only available extract obtained from the bicycle pedals (exhibit bu_p) and attributed by the technical consultant of the Public Prosecutor at the time 'beyond any reasonable doubt' to the victim, was found to be totally negative the following day (20.09.2007), when the same consultant had carried out new analyses. Of these two electrophoretic runs of the 20.09.2007 and the related completely negative traces, no trace was found in any document of the proceedings/trial held against Stasi Alberto".
Legal Stasi: "The whole theory of exchanging pedals fails"
"The moment the DNA on the pedals disappears, the whole theory of exchange, of substitution, disappears, the ghost bicycles disappear, that is, what remains? That it could only have been Stasi because he had confidence in the victim? I think anyone understands that it is a central element of that conviction - said Stasi's lawyer Bocellari -. We can go into review with the exculpatory elements of Stasi or with those new elements that disintegrate the conviction".
Ex Ris Portera: "I did not analyze the DNA found on Stasi's bike"
"I did not personally carry out the genetic analysis of the sample nor did I evaluate or interpret any genetic profile relating to the Garlasco case during my service at the Parma Ris". This was stated by Giorgio Portera, geneticist and retired officer from the force, heard by the Pavia prosecutor's office. "The connection of my person to the analytical activities of the BU_P sample", he specifies regarding the genetic material on the pedals of Stasi's bike, "derives from the registration of an access with my personal user during the last processing phase of the specific trace".

Sempio's defense and the Poggi family: "No new elements"
For Sempio's lawyers, Liborio Cataliotti and Angela Taccia, "there are no new pieces of evidence" and "the alteration of evidence against Stasi has nothing to do with the accusation made against Sempio". Same opinion expressed by the Poggi family: according to lawyers Tizzoni and Compagna, there is no new data. "We hope - they say - that the matter can be submitted as soon as possible to the competent Court of Appeal, which will be able to note the absence of any new element, hopefully putting an end to the improper search for an alternative culprit".
The scenario of a trial review for Stasi
Meanwhile, Stasi's defense asks to "ascertain all responsibilities, so that what happened to Stasi cannot and must never happen again". The reference seems to be to the investigations of the Ris carabinieri, on which however the former general Luciano Garofano, commander of the Scientific Investigations Department twenty years ago, says he is convinced of the "honesty" of his collaborators to the point of excluding irregularities. Even more so, he recalls, that "the analyzes were carried out in the presence of the party's consultants", a detail which in his opinion "clears the field of any doubt". Giada Bocellari and Antonio De Rensis, Stasi's lawyers, have an opposite opinion, speaking of a "sad page for justice" although they say they are comforted by the ability of justice itself to remedy the situation. To present a request for review of the trial there is a need for an element of 'novelty' which is capable of overturning the criminal judgment and demonstrates that the convicted person should have been acquitted. The conclusions of the Pavia Prosecutor's Office could provide several, such as the killer's shoe compatible with that of Sempio and the genetic profile on the bicycle pedal, a fact which for the defense "irremediably directed the investigations of 2007" and on which "a large part of the accusatory castle against Stasi was built", including "the non-existent exchange/replacement of pedals in 2014 and the hypothesis of bicycles that never existed, which then found space in the 16-year prison sentence inflicted on Stasi".
