The search will go on to find out what really happened on the night UK student Meredith Kercher was murdered in Italy four years ago, her family has said.
Speaking after an Italian court cleared Amanda Knox and Raffaele Sollecito of murder, Meredith’s brother Lyle said it felt like it was "back to square one".
Prosecutors say they will appeal. Rudy Guede, 24, – still convicted of the murder – is to seek a retrial.
Knox has left Italy and is on her way to her hometown of Seattle in the US.
