Former State Police inspector Mario Uda and two other witnesses allegedly lied last year during the retrial of Beniamino Zuncheddu, the shepherd from Burcei initially sentenced to life imprisonment for the 1991 Sinnai massacre and then definitively acquitted after serving 33 years in prison.

Fabio Santoni, Rome's deputy prosecutor, is convinced of this, having closed the investigation on the grounds of "false testimony" after the judges of the fourth appeals section of Rome had released the documents following what they heard in court.

Now the lawyers of the accused will be able to read the file and produce documents , request the questioning of their clients or present defense evidence, before the prosecutor decides whether to request a trial.

What got the former police officer into trouble was the retraction of the sole survivor of the massacre , Luigi Pinna, the son-in-law of one of the victims of the triple homicide: after escaping the 1991 massacre, he stated that he had identified Zuncheddu as one of the killers, sentencing him to life in prison. More than thirty years later, however, the key witness later recanted.
