Great article from the Italian newspaper editor for the Umbria Journal, again confirming that the police suspected and planned to arrest Amanda and Raf by the the night of the November 5th. A reminder, this was before any forensic evidence was in. Why is this important? Because it dispels a long-standing talking point that the two were not suspects and the police were taken by surprise when they broke each other's alibi.
(Google translation)
"The first turning point came on 4 November. Well Francesca and Luca Fiorucci come to the office with the news, received from sources close to the investigation, that "Meredith knew his killers." The two reporters of the Journal Umbria, in the afternoon session was completed, the investigators say they do not see clearly the role of Amanda and Raffaele. Half news,
rumors, but qualified. Fois meanwhile piantona the area of ​​mad Grimana
in search of evidence. The next day we go out with the title "Meredith knew who killed her." Let's take into account that the investigation relied on a North African (the indiscretion can
have been leaked on purpose to mislead the investigators, or it was
of confusion on the nationality of Lumumba). Along the same lines the evening news on local television and other newspapers with editorial offices in Umbria
(Courier Umbria, The Nation, The Messenger). The impression is that the
circle is tightening. Arrests are expected. Meanwhile wrecked any attempt to interview Amanda and Raffaele."

I particularly find interesting that the police had apparently warned the press not to interview Amanda and Raf, as their arrests were imminent (if I'm reading that correctly).
