The Daily Mail reports Kercher's family wants American authorities to extradite Knox to Italy to serve out a prison sentence for the murder of their daughter.
The American, nicknamed Foxy Knoxy, has been sentenced to 28 years in prison for the murder of the Leeds University student, who was found half naked with her throat slit in the cottage she shared with Knox in Perugia.
Knox served four years but was freed on appeal in 2011 and immediately returned to the US.
Then this week, a court in Florence sensationally quashed that acquittal, reinstating the guilty verdict. Mr Kercher added: ‘It would set a difficult precedent if the US didn’t uphold their own laws.I didn't follow the Kercher matter in any great detail, so I don't have any opinion as to whether Knox participated in the crime. My objection to allowing the extradition to Italy would be over whether Knox received a fair trial. Most of reasoning I've read on why she is guilty is that she didn't show the appropriate emotions. And, in the back of my mind, I remember that this is the same judicial system that convicted six scientists and a government official to prison for manslaughter for not accurately predicting an earthquake.
