The judicial landscape of one of Italy’s most enduring mysteries has shifted dramatically. For years, the 2007 murder of Chiara Poggi in Garlasco was considered a closed chapter, with the conviction of her ex-boyfriend, Alberto Stasi, serving as the definitive legal conclusion. However, a new investigation led by the Pavia Prosecutor’s Office has fundamentally challenged that narrative, placing the focus on a different individual: Andrea Sempio.
This pivot in the Chiara Poggi murder investigation is not merely a change in suspects but a complete re-evaluation of the crime’s motive and execution. Recent indictments suggest that the evidence used to convict Stasi—specifically a “pornographic motive”—may have been misplaced. In its place, prosecutors are now presenting a theory of a “blind and disproportionate” assault triggered by the rejection of sexual advances, pointing directly toward Sempio.
The case has now entered a volatile phase of forensic re-examination and psychological profiling. As new audio recordings and disputed physical evidence emerge, the legal community and the public are grappling with the possibility that a man has spent years in prison for a crime he did not commit, while the actual perpetrator remained in the shadows.
The Shift in Suspect: From Stasi to Sempio
For nearly two decades, the legal system viewed Alberto Stasi as the sole architect of the crime. Stasi is currently finishing a 16-year sentence imposed after a long and contentious legal battle. However, the Pavia Prosecutor’s Office has recently moved to exonerate Stasi, asserting that new factual elements “completely undermine” the motives previously attributed to him. New forensic analyses have led investigators to believe that the nature of the attack was far more visceral and impulsive than originally theorized.
The current suspect, Andrea Sempio, was summoned for interrogation in Pavia on May 6, 2026, where he exercised his right to remain silent. According to Deputy Prosecutor Stefano Civardi, the prosecution’s theory is that Sempio attempted a sexual approach toward Poggi. When she rejected him, the encounter allegedly escalated into a “furious annihilation focused on the face and head,” suggesting an intent to “erase every trace of the person” who had opposed him.
This new profile suggests a crime of passion and rage rather than the calculated or motive-driven act previously described in court. The prosecution argues that this “blind” violence is more consistent with Sempio’s alleged behavior than with the evidence presented against Stasi.
The ‘Audio Evidence’ and the Mystery of 9:30
Central to the case against Sempio is a series of audio recordings, including one from February 8, 2017. In this recording, Sempio is heard speaking aloud to himself, mentioning that “something happened that day” and specifically referencing “half past nine.” Investigators believe this is a crucial admission regarding the timing of the murder on August 13, 2007.
The time of death has always been the most contested element of the Garlasco case. By pinpointing “half past nine,” prosecutors believe they can place Sempio at the victim’s house at the exact moment of the crime. This temporal realignment is what allowed the prosecution to effectively dismantle the timeline that had previously anchored the case against Alberto Stasi.
Further recordings have surfaced in which Sempio is heard in his car expressing anxiety, stating he is “preoccupatino” (somewhat worried). These soliloquies are being analyzed by criminologists to determine if they represent the guilt of a killer or the stress of a man caught in a complex legal web.
The ‘Note’ Controversy: Evidence or Misunderstanding?
A significant point of contention in the current proceedings involves a piece of paper discarded by Sempio and subsequently recovered by the carabinieri. Prosecutors initially viewed this document as a “script” or a set of notes used by Sempio to coordinate his story and justify his actions—essentially a roadmap for his defense.
However, this interpretation has been fiercely challenged by journalist Marco Nuzzi. Nuzzi has asserted that the document was not a confession or a strategic script, but rather a simple set of notes intended for him. According to Nuzzi, the paper was a communication tool for their professional relationship, and its characterization as “evidence” of guilt is a misinterpretation of its purpose.
This dispute highlights the fragile nature of the circumstantial evidence currently being used to build the case against Sempio. While the prosecution sees a pattern of deception and planning, the defense and associated witnesses describe a series of misunderstandings and coincidences.
Points of Contention in the New Investigation
- The Black Bicycle: There has been renewed debate regarding a black bicycle seen near the crime scene. While some investigators believe it links Sempio to the location, others argue that this detail was previously dismissed or used inconsistently in earlier proceedings.
- The Receipt: A receipt has surfaced that has caused emotional distress for Sempio’s family, with his mother suggesting that a simple mistake in documentation may have contributed to the suspicion surrounding her son.
- The Route: The prosecutor has claimed that Sempio did not pass by the victim’s villa “by chance” after the murder, suggesting a premeditated or observational movement that indicates involvement.
Criminological Analysis and the ‘Script’ Theory
The prosecution has leaned heavily on criminological analysis to interpret Sempio’s behavior. The theory is that Sempio engaged in “soliloquies in search of justifications,” effectively talking himself into a narrative that would protect him from suspicion. Criminologists argue that this behavior is typical of individuals attempting to reconcile their actions with their self-image after committing a violent act.
This psychological approach attempts to turn Sempio’s own words against him, framing his private reflections not as innocent musings, but as a calculated effort to construct an alibi. The defense, conversely, argues that such analyses are speculative and lack the concrete forensic backing required for a criminal conviction.
What Happens Next in the Garlasco Case
The legal proceedings are now moving toward a critical juncture. With the indictment against Andrea Sempio finalized, the court must determine if the “new elements” are sufficient to not only convict Sempio but to formally vacate the conviction of Alberto Stasi.
The upcoming hearings will likely focus on the admissibility and interpretation of the audio recordings and the disputed “note.” The defense is expected to challenge the prosecution’s psychological profiling, while the prosecution will seek to solidify the timeline linking Sempio to the villa at 9:30 PM on the night of the murder.
The next confirmed checkpoint will be the scheduled preliminary hearings in Pavia, where the judge will decide if there is sufficient evidence to proceed to a full trial. This decision will have profound implications for both Sempio and Stasi, as well as for the family of Chiara Poggi, who have sought definitive closure for nearly two decades.
