After spending nearly four hours in questioning, a newly emerged suspect in one of Italy's most infamous murder cases has refused to cooperate with prosecutors—maintaining silence as prosecutors prepare to request his indictment. The Pavia Prosecutor's Office is preparing to move for annulment of a conviction against Alberto Stasi, a man currently serving a 16-year sentence for a crime prosecutors now believe he did not commit based on newly discovered DNA evidence.
Why This Matters
• A 16-year conviction under review: The Pavia Prosecutor's Office is preparing to move for annulment of Alberto Stasi's sentence, potentially freeing him and opening the possibility of wrongful imprisonment compensation under Italian law.
• DNA evidence reopens a closed investigation: Genetic material discovered during recent forensic examination has led prosecutors to identify a new suspect in the 2007 case, prompting them to reconsider the original conviction.
• Formal indictment expected soon: The investigation appears to be moving toward a conclusion, with charges against Andrea Sempio, 39, expected within weeks.
The Original Crime and Its Complications
Chiara Poggi, a 26-year-old economics graduate and Bocconi University student, was killed in Garlasco, a municipality outside Pavia in Lombardy, during August 2007. The case appeared resolved when Alberto Stasi—her boyfriend at the time and also a Bocconi graduate, now 42—received a 16-year prison sentence in 2015. He has been serving that sentence ever since.
Now, that conviction may be reconsidered. Recent forensic examination identified genetic material matching Andrea Sempio, a former phone shop employee who had maintained a casual friendship with Poggi's brother, Marco. This finding has prompted prosecutors to reopen the investigation and identify Sempio as a suspect.
The Pavia Prosecutor's Office has shifted its investigative focus. Rather than the original conviction of Stasi, prosecutors now contend that Sempio may be responsible for the killing, having allegedly acted alone. According to investigative records, prosecutors believe Sempio made unwanted advances toward the victim, was rejected, and subsequently stabbed her.
The Interrogation and Defense Strategy
On Wednesday, Sempio arrived at the Pavia Prosecutor's Office and remained for approximately 160 minutes. Throughout that session, his legal team declined to have him answer questions, instead choosing to listen as prosecutors presented the investigative summary. This approach—accepting interrogation while remaining silent—is a standard legal tactic allowing defendants to hear the prosecution's case without generating statements that might be used against them later.
According to investigative records, prosecutors have presented wiretapped evidence in which Sempio allegedly discussed contacting Poggi before the stabbing and being rejected when he attempted to initiate contact of a romantic or sexual nature. Sempio's defense team has indicated he is prepared to address these claims once he has reviewed complete audio recordings and supporting context.
Sempio's attorney, Liborio Cataliotti, has argued that his client can "explain those wiretaps" once he hears the complete, uninterrupted audio and has time to place the comments in their proper context. Cataliotti emphasized that the transcript version he reviewed contained numerous sections marked "inaudible," and that without full audio, fair assessment of the evidence is difficult.
The Defense Position
Sempio's defense rests on fundamental denial: he claims no romantic connection existed between himself and the victim. Through his legal representatives, he has argued that the sexual motivation theory lacks coherence given that he rarely saw Poggi and that she was typically at her place of employment whenever he visited the Poggi residence to meet with her brother, Marco.
This timeline-based defense—that opportunity and proximity did not align—will likely become central to courtroom arguments if the case reaches trial. Cataliotti has further stressed that without authentic audio recordings, the defense operates at a disadvantage. Partial transcripts and selected excerpts, he contends, may distort meaning and prevent fair assessment.
Witness Testimony and Investigation
Marco Poggi, the victim's brother and the social connection linking Sempio to the household, was also summoned to the Pavia Prosecutor's Office on the same day. His testimony will likely establish the frequency and nature of Sempio's contact with the household and any relevant statements Sempio may have made. As the person who maintained regular interaction with Sempio, Marco occupies a critical position in the investigation.
The Italian Legal Process for Conviction Revision
If prosecutors succeed in their motion to annul Alberto Stasi's conviction, Italian law provides a pathway for potential redress. Under Law 117/1988, individuals whose convictions are overturned due to judicial error are entitled to compensation calculated at daily rates. For a person who has spent years in custody, this can accumulate to a substantial sum—a financial acknowledgment of lost freedom.
The Italian legal system allows for conviction revision when new evidence fundamentally changes the assessment of a case. When prosecutors move to annul a conviction and request that a new suspect be charged, a preliminary hearing judge evaluates the evidence and determines whether sufficient grounds exist to proceed to trial. If the judge authorizes trial, the new defendant faces criminal proceedings while the original defendant's legal team formally pursues conviction revision.
Questions for Italian Justice
The case raises important questions for Italian judicial administration. How did the original 2007 investigation and prosecution result in Stasi's conviction when genetic evidence now points toward a different suspect? These questions speak to forensic standards, investigative procedure, and the oversight mechanisms that should ensure accuracy in serious criminal cases.
Timeline and Next Steps
The Pavia Prosecutor's Office is expected to formally close its investigative phase and request indictment within the coming weeks. At that juncture, a preliminary hearing judge will evaluate the prosecution's case against Sempio and determine whether sufficient evidence exists to proceed to trial. If trial is authorized, Sempio will face criminal proceedings while Stasi's conviction remains subject to formal revision proceedings.
The entire process—from indictment through trial and potential conviction revision for Stasi—could span months or years. Italy's judicial system, though increasingly modernized, proceeds deliberately through complex cases, particularly those with substantial public attention.
For now, Sempio remains free but formally under investigation. He exited the prosecutor's office on Wednesday without addressing journalists, departing by automobile accompanied by his defense team.
The Poggi case has remained prominent in Italian public consciousness not only for its violent circumstances but for what it reveals about forensic evidence, investigative procedure, and the significance of new information in cases once considered closed.
