An Italian court released a document Tuesday that provides the court's reasoning for finding Amanda Knox and her former boyfriend Raffaele Sollecito guilty of murdering British student Meredith Kercher.

The 337-page document examines evidence and the alleged motive for Kercher's murder, according to Oklahoma City's News Channel 4.

The document says two knives were used in the murder, and that fingerprints on Kercher's body indicate that she had been restrained.

The documents also say there was evidence of a strained relationship between Kercher and Knox, including a statement to police that Kercher had accused Knox of stealing money from her room. The argument between the two roommates reportedly occurred shortly before Kercher was murdered.

The court dismissed the theory that the murder was due to a "sex game gone wrong," believing it was out of character for Kercher.

Kercher, 21, was attacked in the home she shared with Knox in Perugia, Italy in 2007. She was brutally attacked, then died after her throat was slit.

Knox and Sollecito were found guilty of the murder in 2008, and were sentenced to 26 years in prison.

In 2011, the murder convictions were overturned, and Knox returned to her hometown of Seattle, Wash.

A re-trial was shortly ordered, and the two were re-convicted on Jan. 30 of this year.

Knox stayed in the U.S. during the re-trial out of fear that she would be convicted.

If Italy's Supreme Court confirms the convictions, it could lead to an extradition fight in which Knox resists being extradited to Italy.

Rudy Guede, an Ivory Coast national and reported drug dealer, was convicted of the murder in 2008. He is currently serving 16 years in prison for the crime.
