Perugia, that single shot that killed Alessandro Polizzi in the middle of the night

Alessandro Polizzi was 24 years old when on the night between 25 and 26 March 2013 he was killed by a gunshot while he slept at the home of his girlfriend, Julia Tosti, who was four years younger. A man broke into the apartment in via Ettore Ricci, in Perugia, in the middle of the night. He had a distorted face and latex gloves on his hands. He broke down the door and immediately headed into the bedroom where the two young people were sleeping. The boys woke up with a start but the man pulled out a gun and fired a shot that reached Polizzi and injured his girlfriend. Then the attacker disappeared but why had he signed that ambush? While fleeing, the man abandoned the gun on the spot, which probably slipped away following the reaction of the 24-year-old who, before falling to the ground, tried to defend himself. The police rushed to the scene that night. Forensics found the weapon and several blood traces not only from the victims. From the analysis of those “details” a genetic profile attributable to Riccardo Menenti was extrapolated and biological traces attributable to the victim and the attacker were also found on the butt of the gun. But who was Riccardo Menenti and why had he signed that ambush that led him to be sentenced to life imprisonment, in all three levels of judgement? Dr. Alessandra La Rosa, the first director of forensics, answers this question and reconstructs the cumbersome work of analysis, verification and comparison.
