An article about the Garlasco crime like hundreds of others that have been written since that August 13, 2007 when Chiara Poggi, just 26 years old, was found dead in the Garlasco villa where she lived with her family. Nothing strange, if it were not for the author, Andrea Sempio. Twice investigated, and twice acquitted, the 37-year-old has ended up under the magnifying glass of the Pavia Prosecutor's Office, where he will appear on Tuesday afternoon for questioning.

On the same day, Alberto Stasi, the victim's ex-boyfriend who was definitively sentenced to 16 years for the crime, and Marco Poggi, Chiara's brother, will also be heard. For the second time in less than a week, Sempio returned to the Carabinieri today to return a cell phone seized on Wednesday during the search he was subjected to. "Just smoke and mirrors," commented lawyer Lovati, who also described as such the search for the possible murder weapon in the Tromello canal, a handful of houses away from the Garlasco villa.

The work tools - including a dovetail hammer like the one that disappeared from the Poggi house - found at the bottom of the canal that runs next to the house of the grandmother of Stefania and Paola Cappa, the twin cousins of Chiara Poggi whose DNA will be taken in the coming weeks, will now have to be examined to establish their possible compatibility with the wounds found on the victim. Complex investigations, also because they were carried out 18 years later, just like the analysis of the genetic traces in the context of the evidentiary incident ordered by the investigating judge Daniela Garlaschelli, at the request of the Pavia Public Prosecutor's Office.

Nothing is left to chance. Not even that article about the crime that Sempio told the police he had written for a journalism course he attended at the Le Vele Foundation in Pavia. "I think it was 2014-2015, Andrea was an introverted boy, but the best in his class," recalls Maria Fiore, a journalist for the Provincia Pavese and a journalism teacher at that Ifts course . "I looked on my computer, but I couldn't find it, he could have written it by hand," she says. "Of course we had talked about the crime in class: it's a story that, because of my job, I've been following since the beginning. In any case, Andrea was really good: in the final exam, an interview, he got 7.5 and the overall final grade was excellent."
