Pavia Prosecutors Probe Uncommunicated DNA Data in Garlasco Case

On October 4, 2026, in Pavia, prosecutors leading the Garlasco murder reinvestigation are focusing on why negative DNA results on Alberto Stasi’s bicycle pedals were allegedly left uncommunicated, milano.corriere.it reported. The inquiry probes whether new RiS testimonies impact the current investigation into Andrea Sempio.

Former Commanders Dispute Roles in Document Transmission

Former commander Garofano stated to magistrates that he merely transmitted documents he had read, while Marino maintained he informed his hierarchical chain rather than interacting with the judiciary directly.

Conflicting Accounts Over Negative DNA Findings

The dispute centers on whether negative secondary DNA tests were deliberately omitted from the case file. Geneticists Francesco Maria Avato and Matteo Fabbri announced plans to sue Marzio Capra after he claimed on television that Stasi’s former defense consultants knew about those results from a September 24, 2007, meeting, an assertion Avato and Fabbri strongly denied, according to milano.corriere.it. Meanwhile, ilpost.it reported that former RiS commander Luciano Garofano dismissed the notion of hidden investigative acts or evidence tampering as science fiction. Il Post also noted that the raw data registers obtained from the RiS of Parma revealed two tests that defense consultants argued could have cleared Stasi nineteen years ago.

The Question of Sample Extraction and New Defense Claims

Giorgio Portera’s name emerged in the investigative records after he confirmed under interrogation that he used the username Port and likely analyzed the samples while loading other procedures into the machine, milano.corriere.it reported. Concurrently, ansa.it and rainews.it reported that Giada Bocellari, defense counsel for Stasi alongside Antonio De Rensis, announced that the defense possesses new elements for an upcoming revision petition. Bocellari stated that one particular element will cause considerable sensation but does not pertain to the original 2007 investigation. Meanwhile, rainews.it noted that Pavia prosecutors forwarded the closing dossier to the General Prosecutor’s Office in Milan to evaluate a potential sentence revision.
