...during the course of Knox’s long and drawn out judicial process, Judge Alessandro Nencini claims, serious attempts were made to tamper with evidence in a way that would favour her….

In the scathing report that spells out the evidence, logic and reasoning that led to his guilty verdict in Florence on 30 January, Judge Nencini also says Knox and her defence tried to tamper with evidence and pervert the truth by introducing prisoners as witnesses, whose testimony turned out to be false and induced by “other interests”.

“It is clear how this trial was subject to heavy evidence tampering, both internally (slander) and externally,” Nencini writes.

He calls the media interest in the case “fertile ground” that led a number of witnesses to give misleading testimony in exchange for their moment in the limelight.

He also slams the first appeal court’s independent experts for having been oddly superficial and illogical in their analysis of the DNA evidence, especially regarding the potential for contamination, noting that controls were in place to prevent it….

Knox and Sollecito were released from prison in 2011 after an appeals court sensationally acquitted them of nearly all charges (one charge against Knox stuck: the slander of Congolese pub owner Patrick Lumumba, who she initially blamed for the crime).

The acquittal ruling, however, was later annulled by Italy’s Supreme Court and a second appeal trial in a jurisdiction outside Perugia was ordered. By that time Knox was safe and sound back in Seattle and chose not to return to Italy for her Florence appeal, instead emailing a statement to the judge, proclaiming her innocence. Sollecito attended.

On 30 January, Judge Nencini and a lay panel of jurors issued a guilty verdict and handed down an even harsher sentence: 25 years for him and 28.5 years for her.

Knox went on national television back in the US the following day claiming, as she always has, that she continues to be the victim of a gross miscarriage of justice carried forward by inertia by dozens of Italian judges.

But in his report, Nencini suggests the gross miscarriage was by Knox and her defence lawyers: indeed, he gave her a longer jail sentence precisely because of the gravity of the slander against Patrick Lumumba aimed at getting investigators off her back.

A small group of fervent supporters continue to lobby on Knox’s behalf and earlier this month she attended an Innocence Project conference with other exonerees, even though Italy’s courts have upheld her convictions….

With this latest development… there appears little wriggle- room for either Knox or Sollecito. Italy’s Supreme Court is expected to give the final ruling on the case after September.
