New investigations into the Garlasco case: the massacre lasted up to 60 minutes.

New scientific investigations into the Garlasco case reveal that the massacre of Chiara Poggi, the 26-year-old killed in 2007, would have lasted between 15 and 60 minutes. This is stated by the consultants for the Pavia prosecutors, the forensic pathologists Cristina Cattaneo and Biagio Eugenio Leone, who have examined the case using immunohistochemical techniques not available in the past.

The long duration of the attack, during which the victim is believed to have put up an active defense, appears incompatible with the prosecution's reconstruction against Alberto Stasi, the only person sentenced to 16 years for the crime. According to the Supreme Court, Stasi would have had only 23 minutes to make the bicycle trip, kill his girlfriend, and return home. The new analyses highlight numerous defensive wounds on Chiara Poggi's body.

The presence of DNA traceable to the paternal line of Massimo Giuseppe Sempio (another suspect) under the victim's fingernails and the imprint of a "fresh and wet" palm on the cellar wall, attributed to Sempio, take on new meaning in light of a prolonged struggle. The prosecutors accuse Sempio of the murder following a rejection of a sexual advance.

The Garlasco case is one of the most notorious and controversial Italian murders of recent decades. It all began on August 14, 2007, when 26-year-old Chiara Poggi was found murdered in the basement of her family's villa in Garlasco, in the province of Pavia. The body showed numerous stab and slash wounds.

The investigation initially focused on the victim's boyfriend, Alberto Stasi, a Bocconi University student, who was sentenced in the first instance in 2010 to 16 years in prison. The verdict was upheld on Appeal and by the Supreme Court. The judicial reconstruction pointed to him as the sole perpetrator, with a crime of passion as the motive. However, the case has never been definitively closed in the public opinion and for a part of the investigation.

Parallel to this, from the earliest investigative stages, another lead emerged involving Massimo Giuseppe Sempio, a family friend of the Poggi family, who was 17 at the time of the events. Suspicion fell on him due to biological traces and a palm print found at the crime scene. The investigations into Sempio, separate from those into Stasi, have continued over the years, with the Pavia prosecutors believing him to be the true perpetrator. The new technical analyses in 2026 have reopened the debate on the timing and dynamics of the murder, calling into question the temporal alibi that formed the basis of Stasi's conviction.
