Crucial findings from the re-analysis of an oropharyngeal swab taken from Chiara Poggi 18 years ago during her autopsy are expected imminently. The tests form part of a preliminary evidence hearing ordered to investigate a new theory pursued by the Pavia Prosecutor’s Office and the Milan Carabinieri Investigative Unit. This theory focuses suspicion on Andrea Sempio, accused of murdering the young woman with one or more accomplices. Investigators are seeking evidence to support this hypothesis, which could redefine the understanding of the crime for which Alberto Stasi is currently serving a 16-year prison sentence.
Last Friday, following initial test results, geneticist Denise Albani – appointed as an expert witness by Pavia preliminary investigations judge Daniela Garlaschelli – conducted a session to consolidate the existing data. Of the five samples tested, three yielded no usable results. The other two identified male DNA: one profile was designated “Unknown 3”, while the other was traced back to the assistant of the coroner who performed the autopsy in 2007.
The results, anticipated from today onwards, are set to resolve a critical juncture in the investigation. Should the currently unidentified biological profile *not* be contamination – as many consultants involved suspect it might be – authorities will need to identify the source of this Y chromosome (which is attributed neither to Sempio nor to Stasi) and determine the context for its presence at the crime scene.
To date, the preliminary evidence hearing has not produced any element supported by concrete proof that would necessitate rewriting the investigation into the Garlasco murder.
