Why It Matters
Chiara Poggi was killed in Garlasco on 13 August 2007. Alberto Stasi was convicted of the murder after a long trial.
A worksheet recently recovered by the Pavia Prosecutor's Office reports further DNA analyzes carried out in 2007 on Alberto Stasi's bike. Tests and raw data that were never included in the trial documents also emerge from the Ris archives, fueling new questions about the investigations carried out after the murder of Chiara Poggi.
New elements emerge in the investigation into the murder of Chiara Poggi, the 26-year-old killed in the family villa in Garlasco on 13 August 2007. Among the documents recently acquired by the Pavia Prosecutor's Office appears a document from the Parma Ris which, according to the prosecutors' consultants, was never included in the reports sent to the investigators at the time.
The worksheet never filed
This is a "worksheet" recovered last September 11th in the Ris archives. The document reported the analysis of a DNA sample, again referable to Alberto Stasi's bike, indicated as "bu_p_bis", dated "26 September 2007" and quantified partly as "human DNA" and partly as "male DNA". The detail is contained in the latest consultancy from the prosecutors signed by the experts Previderé and Grignani.
The analyzes beyond the official report
The consultants explain that "the pedal inspection operations" by the RIS, in particular by Captain Alberto Marino, continued even after 24 September 2007 (the date of filing of his report), "generating numerous other samples with the suffix 'bu_p'", described in the minutes but not accompanied by all the technical documentation that has emerged today from the archives.
Blood tests and inconsistencies
From the documents recovered, raw data also emerged relating to two null results from 20 September 2007 that were never filed and conflicted with a match from the day before with Chiara Poggi's DNA. The same documents also contain a note attributed to Marino which refers to an Obti test, used to look for human blood on the tracks on the pedals, which would have given a negative result. However, there is nothing about this analysis in the documents at the time. An element that adds to an already complex picture. In the report of 24 September 2007, in fact, Marino had claimed that the DNA found on the pedals belonged to Chiara Poggi "beyond any reasonable doubt" and had reported the presence of microtraces of blood consistency which tested positive in the Combur test.
The node on the origin of the traces
Among other things, a technical operations report from the following day shows that Alberto Stasi's then defense consultant had asked for an Obti test to be carried out, but Marino had replied that that type of investigation was not useful, given the "extremely limited" traces. Furthermore, on 10 September 2007, when the operations began, the consultant Fabbri had already written in a technical note: "Combur test negative, Luminol negative". After the arrest on 24 September, Stasi was released from prison also because the investigating judge had clarified that it could not be said that that DNA was blood.
Open Questions
- Why was the document not included in the original documents?
- What impact will this data have on past sentences?
