Italy's highest court overturned the murder conviction of Amanda Knox and her Italian ex-boyfriend Raffaele Sollecito on Friday, the AP reports.

Last year, a Florence appeals court convicted Knox and Sollecito in the 2007 death of Knox's former roommate, Meredith Kercher. After a thorough examination, the supreme Court of Cassation concluded the evidence could not support the conviction. Their reasoning will be released within 90 days.

Both Knox and Sollecito have maintained their innocence throughout the case, claiming they spent the evening at Sollecito's apartment the night Kercher, 21, was murdered and sexually assaulted in the apartment she and Knox shared with two other students.

Another man, Rudy Guede from Ivory Coast, was eventually arrested, tried and convicted of her murder in a separate trial. He is currently serving a 16-year sentence.

The court's ruling is the final decision on the matter.
