New DNA evidence reignites Garlasco murder investigation

Geneticist Ugo Ricci extracted DNA from a coffee cup used by Andrea Sempio and matched it to the Y‑chromosome profile found under victim Chiara Poggi’s fingernails, contradicting earlier forensic conclusions that excluded Alberto Stasi. The discovery adds to a growing body of circumstantial evidence that could lead to a revision of the case, originally resulting in Stasi’s final conviction for the 2008 murder in Garlasco, Italy.

During the July 3, 2026 episode of the TV program Quarto Grado, host Gianluigi Nuzzi highlighted Colonel Gennaro Cassese’s repeated “non ricordo” responses to questions about the investigation and presented a third version of a Vigevano parking receipt that Sempio claims proves his presence elsewhere on the day of the crime. The combination of new forensic data and revisited procedural details has intensified public and judicial interest in re‑examining the long‑standing case.

The Garlasco murder case, now nearly two decades old, remains one of Italy’s most controversial unsolved crimes, with renewed scrutiny focused on DNA evidence, investigative conduct, and the reliability of testimonies from key figures.
