Waste DNA Analysis Ties Alberto Stasi to Crime Scene, Clears Andrea Sempio

New DNA results from Poggi’s household waste show matches only for Chiara Poggi with a secondary male profile linked to Alberto Stasi.

Overview

  • Forensic tests on plastic plates, yogurt lids and waste bags from the 2007 crime scene detected only Chiara Poggi’s DNA and a male profile attributed to her former partner, with no genetic material from Andrea Sempio.
  • Andrea Sempio’s lawyers say the absence of his DNA in the household waste supports their client’s repeated claim that he never entered the residence on the morning of the murder.
  • Investigators recovered a three-centimeter hair with an intact bulb from an unopened trash bag, which is now undergoing nuclear DNA analysis to establish its origin.
  • A hotel manager in Falzes reported that only Chiara’s parents stayed at the family’s Trentino lodging in August 2007, directly contradicting brother Marco Poggi’s long-standing alibi.
  • The Pavia prosecutor has ordered a 3D remapping of the Poggi villa and is reviewing previously unexamined fingerprints as part of ongoing efforts to reconstruct the events inside the home.
