Azouz Marzouk , husband of Raffaella Castagna and father of little Youssef , two of the four victims of the massacre in Erba (11 December 2006), was sentenced to two and a half years in prison , for aggravated defamation against his ex brothers-in-law, Beppe and Pietro Castagna .

According to the Como judge Veronica Dal Pozzo, Marzouk "has defamatory behavior of extreme gravity , with insinuations that have fueled the innocentist current on the massacre , and the denigration of the offended parties already distorted for the first time by the heinous murder of their family members , and again overwhelmed by the impressive media resonance of the unfounded accusations against them".

The prosecutor's request was for one year and three months, a penalty that was later doubled in court. Marzouk, in an article published on a website in February 2019, claimed that the massacre had an economic purpose : «Investigate the family, my son Youssef knew the killer. Someone close to my wife killed him. You only need to read the papers to understand that someone wanted my wife's inheritance».

The reference to the family of the victims was clear to the judge and in the sentence he underlined the "special negative value" of this behavior under two profiles: «Not only that the accusation came from their own brother-in-law, but also and above all that it was part of the flow of an innocentist and revisionist current of the trial, resulting in a real disinformation campaign, made up of sibylline allusions and blatant denigrations, brutally damaging to the reputation of the Castagna brothers».

A conduct carried out "in the awareness of the falsehood of the accusations against them", concludes Dal Pozzo.
