Garlasco crime: investigations closed for Andrea Sempio, new wiretaps and clarifications on the DNA

“I hope full light will be shed on the favorable evidence not filed,” Alberto Stasi confided to his lawyer, referring to the negative tests on Chiara Poggi's DNA on the pedal of her bike. Now he can believe in the review of the trial. “I have never analyzed the genetic traces found on the bicycle,” says geneticist and Army officer Giorgio Portera. Example towards the request for indictment

The Pavia Prosecutor's Office has closed the investigation into the Garlasco crime. For the murder of Chiara Poggi, which occurred on 13 August 2007, the only suspect is Andrea Sempio. "What I can tell you is that my son had absolutely nothing to do with the murder of Chiara Poggi", said Daniela Ferrari, Sempio's mother, interviewed by Tg3. "We wait as we all wait, but we don't care because my son is innocent. The only thing we are sure of is that my son is a total stranger."

New wiretaps in the documents of the investigation into Sempio

In the new documents of the investigation by the Pavia Prosecutor's Office, against Andrea Sempio for the murder of Chiara Poggi, there are also a series of environmental wiretaps, which had not been filed with the first conclusion of the investigation notified on 8 May. From what has been known, one of the themes at the center of the new investigations on the 38-year-old clerk and his family always concern issues that have already emerged in recent months, such as the first investigations of 2016-2017 against him which were archived. Interceptions that are added to all the consultancies, notes and reports whose results were summarized by the prosecutor Fabio Napoleone in a long note. And to the testimonies of the former members of the RIS who dealt with the scientific investigations and above all with the question of DNA on the pedals.

Ex Ris Portera: "I didn't analyze the DNA on the bike"

Giorgio Portera, geneticist and retired officer from the force, heard by the Pavia prosecutor's office in the new investigation, said: "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". A clarification arrived after the note in which the prosecutor Napoleone put in black and white the elements of the consultancy, including a consultancy presented by the defense of Alberto Stasi, convicted of the crime, who working on raw data obtained from the Pavia Prosecutor's Office in November 2025, highlighted that two "counter-analyses" of 20 September 2007 had established that it was not Chiara's DNA that was on the pedals of the burgundy bike, the first seized. The former commander of the RIS Luciano Garofano also returned to the issue. "I blindly believe in the honesty of my collaborators," he assured. There was "no conspiracy" and this is demonstrated by the progress of the trial.
