In what judgements were Mignini's theories on Narducci confirmed by the courts?
Well, just to start, basically in both the Narducci investigations lead by Mignini.
Because you know there were two Narducci investigation files: the first was for the murder of Narducci, it was started after the unburial of Narducci's body. The second was on the side trackings, the corpses exchange.
The first investigation was the most complex one, ended as Mignini asked for the archiviation without indicting anyone. He slated some formal suspects (Calamandrei, Spezi, others) and asked the preliminary judge to not indict anyone because elements were not sufficient to indict specific people. However, that research made great findings about the truth, there were sufficient elements to conclude that the body picked at the lake was not Narducci's, that F.Narducci was killed, and also that Narducci was involved with the MoF murders.
Mignini submitted a 64-page document with the summary of such investigation.
The preliminary judge De Roberti accepted wholly Mignini's conclusions, and she issued a 12-page motivations order of archiviation which is now judicial truth. Calamandrei and Spezi appealed at the Supreme Court to have this document annulled, but the SC rejected their appeal.
Subsequently, in the second investigation Mignini asked to indict 20 people. Micheli rejected the requests and dropped all charges. Mignini appealed at the Supreme Court. This time the SC accepted Mignini's appeal, and annulled almost all of Micheli's dropping of charges; it only accepted the dropping of "criminal association" (mafia) charge, but re-instated all the other 21 charges. The "criminal association" charge was dismissed in point of law, because it's a charge with very peculiar legal elements, while the charges about the single crimes committed by the conspirators were all re-instated. Several of those charges however meanwhile had expired, the Cassazione noted recent expiration for some of them (thanks to Micheli's 1-year delay before depositing the motivations), other expired shortly afterwards.
The last of Spezi's charge was dropped on request of prosecutor Duchini as it expired as well. Brizioli's charge instead still stands, and now he is under trial.
The poin it SC anyway accepted Mignini's investigation was valuable and correct, although, being a Cassazione rulling, it did not get so much into the merits of body swaps and evidence assessment as the De Roberti ruling did.
Another trial which confirmed Mignini's theory was the Ticchioni case, which was a defamation case where the judge found out that a testimony by a fisherman who witnessed the body "placing" was authentic.
There was another case in Milan, this one a calunnia case against Spezi, that ended with the court of Milan acknowledging that Mignini's investigation was correct and the body swap actually occurred and called that a "fact".
The double body swap? Criminal association among the Florence 20? How were Mignini's theories approved, and which ones?
See above.
When did the MOF case get re-opened? Who is leading the investigation, Giuttari? I thought Calamandrei had died? Who is Reinecke? Will they be testing the "Scopetti Rag", a blood stained rag from a crime scene, through modern DNA techniques?
The investigation on the "masterminds" is now opened and focused on deceased Reinecke, a resident of Villa La Sfacciata, he is the man who found the two young men in the van. Mario Vanni before dying also accused a black man, an American citizen and a homosexual, who used to live together with Reinecke, naming him as the man who physically shot some victims. The man has also died of AIDS meanwhile.
Reinecke owned a motor boat at the Trasimeno lake and he was caught with a series of illegally detained firearms. He used to be a fanatic of exhoterism, used to dress in black and wear gold medallions portraying the devile, his second wife claimed she detected the minivan murders thanks to her paranormal powers.
I also thought Italian TV was softening up the public for the acquittals in the weeks before the verdict, through the coverage on TV. Especially having Dr Peter Gill to explain the errors in DNA interpretation by the Chieffi court in requiring contamination to be proven. And the positive and sympathetic coverage of Raffaele and also Amanda.
Indeed everything talked about a "political" verdict, but the Porta a Porta show included Roberta Bruzzone who pointed out that Knox was certainly guilty. And was not about "sympathy" for Amanda, it was instead about the "separation of evidence" between Sollecito and Knox.
By the way, I saw a post on an internet blog claiming every single reference on Roberta Bruzza(?)'s resume was falsified. She's the tall woman who looks like a model and claims to be a forensic expert, and was claiming she thought Raf was guilty. Do you know anything about this, and is it rrue she was allowed to testify in an actual court case as an expert, while in fact she was and is a complete fraud? (Her response to being exposed as a fraud, was that she was being stalked).
Roberta Bruzzone is a criminologist and a criminal profiler, not a forensic expert. I have no clue whether she is a fraud. Anyway defence experts are all liars, they get paid for that.
Annoying
