On February 25, 2027, the judges of the Pavia court will open the preliminary hearing against Andrea Sempio, accused of the murder of Chiara Poggi, which occurred in Garlasco on August 13, 2007. The request for indictment presented by the public prosecutor contains a list of 24 sources of evidence, the result of investigations resumed in 2025 and the retrieval of previous proceedings.
These elements constitute the core on which the Prosecutor's Office intends to base its accusation, providing the judge with a complete set of technical, testimonial, and documentary evidence.
Telephone evidence and wiretaps
Among the first elements collected were the telephone records of the Garlasco municipal switchboard from August 13, 2007, the day of the crime, and those of the Poggi family from January to August of the same year.
The data shows the calls made by Sempio to the victim's home in the days preceding the crime, providing a timeline of the communications. Furthermore, the Prosecutor's Office included wiretaps conducted by the Milan Carabinieri Investigative Unit, which include audio and telephone recordings collected in 2026, as well as the information reported in the Carabinieri's communication dated April 21, 2026.
Technical and scientific consultancy
The investigative component is enhanced by eight specialist consultations. Bloodstain Pattern Analysis , conducted by Lieutenant Colonel Andrea Berti, reconstructed the dynamics of the blood drops at the crime scene. Forensic pathologist Cristina Cattaneo assessed the time and cause of death. A duo of experts, Gianpaolo Iuliano and Nicola Caprioli, examined footprint 33 on the wall of the house on Via Pascoli, attributing it to Sempio, and performed a technical footwear analysis linking the shape of the polka-dot sole to the defendant's activity. Genetic analyses by Carlo Previderè and Pierangela Grignani identified DNA on the victim's fingernails, compatible with Sempio. Other contributions include IT consulting by Paolo Del Checco on Alberto Stasi's computer, and the three-dimensional reconstruction of the crime by engineer Simone Tiddia, as well as two technical notes from the RACIS regarding footprint 33 and biological traces on wall surfaces.
The testimonies and the seized documents
The file also contains statements from key witnesses. Marco Poggi, Chiara's brother, was interviewed on three separate occasions (March 10, 2025, May 20, 2025, and May 6, 2026). Testimonies are also included from friends of the Garlasco group (Mattia Capra, Alessandro Biasibetti, and Roberto Freddi), as well as from the cells of Aldo Mattei, a former Carabiniere of the RIS (Italian National Intelligence Agency), who was also interviewed regarding possible critical issues with the original investigations. The Prosecutor's Office also seized notebooks and manuscripts found in the homes of Sempio and his parents, as well as all documents produced during the 2016 investigation, now closed but reopened following new evidence.
The investigative framework for the next hearing
The complex body of evidence, which includes preliminary investigations (latent fingerprints, DNA analysis by Denise Albani, and fingerprint analysis by Giovanni di Censo) and the Cagliari RIS report on the "V" blood traces and the "zero step" blood trail, is scheduled to be evaluated by preliminary hearing judge Luigi Riganti. The prosecution will be tasked with proving that all these elements point to Sempio's guilt, while the defense will challenge their reliability and relevance. The outcome of the preliminary hearing will determine whether the case will proceed to a full trial.
