The overturning of Amanda Knox's murder conviction was explained in 144-pages from the Italian appeals court Thursday.

According to The Associated Press, the Perugia court said faulty evidence was used to convict Knox and her Italian boyfriend, Raffaele Sollecito, of the murder of 21-year-old Meredith Kercher. The deficiency included no murder weapon, untrustworthy DNA, an inaccurate time for the killing and insufficient proof that the couple was at the crime scene.

The evidence, even if taken in its totality, does not prove in any way that Amanda Knox and Raffaele Sollecito are guilty of the murder of Meredith Kercher, the court wrote according to ABC news.

The document also said that the judges do not confirm the hypothesis that there were many people necessarily involved in the murder.

According to The Associated Press, the appeals court agreed that there was substantial proof for the charge of slander against Know, who was convicted of falsely accusing a bar owner of the murder, and that Knox and Sollecito's alibis did not match up.

The only elements that are sustained don't allow the belief, even when put together, that the guilt of Amanda Knox and Raffaele Sollecito for the crime of murder ... has been proven, the court said.

Knox, now 24, and Sollecito, now 27, had their guilty verdicts thrown out Oct. 3. Rudy Guede was also convicted for the murder in a separate trial, but has exhausted his appeals.

Knox's English college roommate, Meredith Kercher, was found in a pool of blood on her bedroom floor in Perugia on Nov. 1, 2007. Knox and Sollecito were arrested three days later and convicted and sentenced to 26 year and 25 years respectively on Dec. 4, 2009. The appeal process began Nov. 24, 2010.

After being released and credited for time served for the slander conviction, Knox immediately flew home to Seattle.
