"having illegally extracted confessions from Knox and trumpeted to the press the subsequent arrests of Knox, Sollecito and a third man – whose name had, according to Preston and Spezi, been suggested to Knox under duress by interrogators – not to mention leaking details of the interrogation to the press, Mignini's, initially 'satanic', sex-game-gone-wrong scenario became 'fact'.
"But with the arrest of Rudy Guede, a drug-dealing drifter with a history of burglary and harassing women, and whose DNA was all over the crime scene, Mignini came under real pressure.
"With all the evidence now pointing to Guede, rather than Knox and Sollecito, and with the Monster investigation fiasco looming, Mignini, desperate to keep his sex-game-gone wrong scenario alive, released the Knox-named suspect and simply substituted him with Guede, even though Guede had never met or known Knox or Sollecito.
"In his subsequent defence Guede did not play ball. He never mentioned Knox or Sollecito, sticking to his story that he and Meredith had had consensual sex, that he had left and some other third party had committed the crime. In the US, detectives call this the SODDI defence, as commonly employed by rapist-murderers: 'We had sex. I split. Some Other Dude Did It.'
"Preston and Spazi document Mignini's subsequent campaign to stand the sex-game story up – investigators rounding up helpful witnesses, repeated examination of the crime scene, and then, after five months in prison, Guede changing his story completely to fit the Mignini plot line, the 'other Dude' being Raffaele Sollecito, and so on. DNA was eventually found, months later, linking the couple to the scene and the rest is history. Mignini got his conviction and his face was saved."
