the alarm and brought the police, which made the prosecution's assertion that she had been trying to delay discovery of the body untenable. Her and Sollecito's accounts failing to completely match did not constitute evidence they had given a false alibi. Discounting Curatolo's testimony as self-contradictory, the judges observed that he was a heroin addict. Having noted that there was no evidence of any phone calls or texts between Knox or Sollecito and Guede, the judges concluded there was a "material non-existence" of evidence to support the guilty verdicts, and that an association among Sollecito, Knox, and Guede to commit the murder was "far from probable". The false accusation conviction in relation to her employer was upheld, and Judge Hellman imposed a three-year sentence although this was nominal, being less than Knox had already served. She was immediately released, and returned to her Seattle home. Knox wrote a letter to Corrado Maria Daclon, Secretary General of the Italy–USA Foundation, the day after regaining her freedom: Retrial On March 26, 2013, Italy's highest court, the Supreme Court of Cassation set aside the acquittals of the Hellmann second level trial on the grounds that it had gone beyond the remit of a Corte d'Assise d'Appello by not ordering new DNA tests and failing to give weight to circumstantial evidence in context such as Knox's accusation of the bar owner in the disputed interviews.

A retrial was ordered. Knox was represented, but remained in the United States. Judge Nencini presided at the retrial, and granted a prosecution request for analysis of a previously unexamined DNA sample found on a kitchen knife of Sollecito's, which the prosecution alleged was the murder weapon based on the forensic police reporting that Kercher's DNA was on it, a conclusion discredited by court-appointed experts at the appeal trial. When the unexamined sample was tested, no DNA belonging to Kercher was found. On January 30, 2014, Knox and Sollecito were found guilty. In their written explanation the judges emphasised Guede's fast-track verdict report was a judicial reference point establishing that he had not acted alone. The Nencini verdict report said there must have been a cleanup to remove traces of Knox from the building while
