Kercher murder trial: Call to jail Amanda Knox for 30 years
Italian prosecutors have asked for a 30-year prison sentence for former US student Amanda Knox in a retrial over the murder of her British housemate.
Prosecutors also requested that Ms Knox's ex-boyfriend Raffaele Sollecito receive 26 years for the 2007 killing.
Mr Sollecito and Ms Knox were convicted in 2009 of murdering Meredith Kercher but acquitted on appeal in 2011.
In March, Italy's highest court overturned the acquittals and ordered a new trial.
Mr Sollecito has attended the trial in Florence but Ms Knox returned to the US after the appeal and is being tried in absentia. Both have always protested their innocence.
In more than 10 hours of closing arguments, prosecutor Alessandro Crini said DNA evidence - which is highly disputed in the case - showed Mr Sollecito and Ms Knox had stabbed Ms Kercher while another man, Rudy Guede, sexually assaulted her.
Guede, from Ivory Coast, was convicted in a separate trial and sentenced to 16 years for the killing.
Mr Crini criticised the previous appeals court ruling, saying it had made the mistake of "isolating" individual pieces of evidence without looking at the full picture.
The supreme court had "wiped out" that ruling, he said.
Meredith Kercher, from Coulsdon, south London, was found dead in a flat she shared in Perugia with Ms Knox, a fellow exchange student.
Prosecutors said Miss Kercher, who had been repeatedly stabbed, died in a sex game that went wrong. She was 21.
Ms Knox insists that on the night of Miss Kercher's death she was at Mr Sollecito's flat, smoking marijuana and watching a film.
The retrial is expected to reach a verdict in January.
