Defense attorneys for Andrea Sempio are preparing to submit five technical reports to the Pavia Prosecutor’s Office by October 18, aiming to challenge the evidentiary basis of the murder investigation into the 2007 death of Chiara Poggi. Lead counsel Liborio Cataliotti, working with Angela Taccia, stated that these expert findings are intended to refute the prosecution’s case point-by-point ahead of a expected request for indictment.
Defense disputes evidence using footprint sizes
The defense team identifies the size of footprints found at the crime scene as a central point of contention. According to Cataliotti, there are 25 footprints attributed to the perpetrator at the scene, all of which are smaller than the size 44 shoe that Sempio has consistently worn. To support this, the defense has utilized 3D instrumentation to create casts of the prints and conducted mechanical tests using four Frau-model shoes, the same brand identified in the crime scene evidence. The defense argues these results are incompatible with Sempio’s foot size, with estimates for the crime scene prints ranging between sizes 39 and 41.

Analysis of the trace evidence and DNA findings
The defense is also challenging the interpretation of other physical evidence, including the “traccia 33″—a handprint found on a wall near where the victim’s body was discovered. Consultant Armando Palmegiani stated that the team performed an Obt test, which they claim demonstrates that the trace does not contain blood, contradicting the prosecution’s position.
Expert Insight: The defense strategy focuses heavily on physical inconsistencies to force a re-evaluation of the prosecution’s theory. By prioritizing laboratory-tested physical measurements over contested genetic material, the legal team seeks to create enough technical doubt to potentially avoid a trial during the preliminary hearing stage.
Next steps in the judicial process
The defense expects to finalize and deposit all five reports by the end of the week. Once the documentation is submitted, the case will return to the Prosecutor’s Office, led by Fabio Napoleone, for a decision on the request for indictment. If the prosecution proceeds, the court will then evaluate the evidence during the preliminary hearing phase, where Sempio hopes to resolve the matter without a full trial.
Frequently Asked Questions
What is the deadline for the defense to submit their findings?
The defense must present their technical reports and counter-analyses to the Prosecutor’s Office by October 18.
Why does the defense believe the shoe prints are critical?
Attorneys argue that the 25 prints found at the scene are consistently smaller than the size 44 shoe that Sempio has always worn, which they contend makes his involvement physically incompatible with the evidence.

What is the status of the “traccia 33” evidence?
The defense claims that their testing with the Obt test on the wall where the print was found indicates that the trace does not contain blood, a conclusion they state is opposite to the findings presented by the prosecution.
As the October 18 deadline approaches, will these new technical reports be sufficient to alter the prosecution’s current trajectory in the Garlasco case?
