At the time of Knox's trial, Mignini was under indictment for abusing his office in another, unrelated murder case, the Florence serial killings. This week an Italian court convicted Mignini in that case. According to CBS:
In Mignini's "abuse of office" case, Florence prosecutors have alleged that Mignini used his office to harass journalists who criticized his investigation of the Florence murders. They allege he illegally wiretapped journalists and opened bogus investigations against them.Incredibly, Mignini has been allowed to continue his role as a prosecutor while appealing his conviction. If his conviction is upheld, Mignini faces ten months in prison.

Update: Since I posted this, I have come to believe that Amanda Knox and Raffael Sollecito are innocent of the crime. See Injustice in Perugia, a site detailing the wrongful conviction of Amanda Knox and Raffael Sollecito.
