Garlasco, the investigation into Sempio
The Pavia Prosecutor 's Office 's investigation into Andrea Sempio has concluded, and the decision on whether to dismiss the case or commit it to trial now rests with the judicial authorities. According to the prosecutors, Chiara Poggi's DNA was not found on the pedals of Alberto Stasi 's bike.

The new wiretaps
New wiretaps have emerged documenting alleged tensions within the Sempio family over old investigations. This is fueling the debate in the studio, but it's not a safe bet.
