Foxy Knoxy cut friend's throat 'on impulse' after sex attack, reveal judges
RULING: She got excited by holding down girl pal
Killer Amanda Knox acted on impulse and not out of "any animosity or feeling of spite", according to the judges who sentenced her for murder.
The American student, dubbed 'Foxy Knoxy' during the trial, was convicted last year of taking part in the murder and sexual assault of her flatmate Meredith Kercher in Perugia.
Releasing the reasoning behind their verdict, the judges said Knox had killed her roommate as the result of "casual contingencies".
The murder had not been planned or premeditated.
Prosecution witnesses, including friends of Ms Kercher in Perugia, testified during the trial that Ms Knox had fallen out with her flatmate over missing cash, bathroom hygiene and Knox's habit of bringing "strange men" back to the hillside cottage they shared with two Italian women.
Knox (22) was sentenced last December to 26 years in prison for her part in the murder, while Raffaele Sollecito (25) her former Italian boyfriend, was given 25 years.
Their first of two appeals is expected in the autumn.
A third suspect, Rudy Guede, an Ivory Coast immigrant, was sentenced to 30 years for the murder in a separate trial under fast track procedures. His sentence was reduced to 16 years on first appeal, and he is awaiting a second final appeal.
Prosecutors claimed that Sollecito had held Ms Kercher down while Guede assaulted her sexually and Knox cut her throat with a kitchen knife later found in Sollecito's flat. In a riposte to Knox's family and friends who claim she was the victim of a mistrial based on flawed evidence, the judges said the prosecution had drawn "a comprehensive and coherent picture, without holes".
The defendants had been able to describe Ms Kercher's injuries, and their guilt was clear from DNA traces and naked footprints found "in various parts of the house".
The judges said it was Guede who had carried out the sexual violence, with Knox and Sollecito -- who were under the influence of drugs -- "actively participating" by helping him to subdue Ms Kercher so that he could "give vent to his lustful impulses".
The motive was "erotic sexual violence" in which Knox and Sollecito had "actively collaborated" in Guede's "evil act". They had probably found subjugating Ms Kercher "exciting".
Last month Knox's separated parents, Curt Knox and Edda Mellas, claimed on the Oprah Winfrey show that their daughter had been the victim of "trial by media".
Ms Mellas said: "She's absolutely always maintained that she never had anything to do with it. Meredith was her friend, they were great friends."
The Knox family allowed cameras into their Seattle home as they waited for their weekly ten-minute Saturday morning phone call from Knox.
Mr Knox said his daughter, who continues to profess her innocence, had "good and bad days", and on one of his visits to her in prison had "cried in my arms for 45 minutes".
