Knox and her then-boyfriend Raffaele Sollecito were convicted in 2009 of murdering Kercher. Knox was sentenced to 26 years in jail, Sollecito to 25. Sollecito was also released Monday.
The jury spent 11 hours deliberating on whether they should overturn the conviction in light of new DNA evidence that weakened the prosecution's argument that Knox's DNA was on a knife found at the scene.
