Amanda Knox and Meredith Kercher were engaged in an ongoing dispute over money which culminated in a fight on the night of her death, an Italian court has said.

The appellate court in Florence, which in January found Knox guilty of the murder, today issued a 337-page document explaining its decision.

It claimed there was evidence that the two roommates had a bad relationship despite Knox’s claims to the contrary.

And it stated the third person convicted in the murder, Rudi Guede, did not act alone because Kercher’s wounds showed signs of “multiple aggressors”.

These included evidence of two knives at the scene as well as finger imprints on her body, which indicate that Guede was not the sole attacker, according to the report.

The report also drew attention to statements given by Guede under police questioning which, it alleged, indicated that Kercher believed Knox had stolen money from her room.

“It is a matter of fact that at a certain point in the evening events accelerated; the English girl was attacked by Amanda Marie Knox, by Raffaele Sollecito, who was backing up his girlfriend, and by Rudi Hermann Guede, and constrained within her own room,” the document said.

The judges said there was evidence of "two different weapons" on the neck wounds of the victim.

"The court believes the knife which produced the injury on the left side of the victim's neck where the greatest amount of blood flowed and caused the death of Meredith Kercher was held by Amanda Knox," the judges said.

The document ruled out that the murder was attributable to a sex game gone wrong, citing that such a scenario would have been out of Kercher’s character.

And it stressed that the assailants did not have to have the same motive for attacking the British student.
