Garlasco murder case: DNA discrepancies emerge in 2007 RIS reports

Garlasco murder DNA evidence Alberto Stasi RIS Carabinieri Chiara Poggi

New developments in the Garlasco murder investigation have centered on DNA analysis performed by the RIS (Scientific Investigation Department) in 2007. While an initial test on September 19, 2007, reportedly showed a match with the profile of victim Chiara Poggi on the pedals of Alberto Stasi's bicycle, two subsequent tests on September 20, 2007, yielded negative results.

The Pavia Prosecutor's Office has noted that there is no record of these negative results in the official case files from that period. Alberto Marino, the expert who conducted the tests, testified that he informed his hierarchy about the findings but did not contact judicial authorities directly. He described the decision to repeat the test as an attempt to further investigate the initial findings.

Former RIS commander Luciano Garofano has denied any intention to frame Alberto Stasi, asserting that the positive DNA match was never in doubt and that the laboratory acted transparently. Conversely, former deputy Marco Pizzamiglio has alleged that operations under Garofano were managed with an emphasis on media visibility. The emergence of these raw data has reignited debate over the validity of the evidence that led to Stasi's conviction.
