The legal battle continues for Amanda Knox, on trial to prove her innocence for the third time in the murder of her 21-year-old British roommate.
Her defense team faced a rocky start as her retrial began in Florence, Italy, Monday.
“The judge rejected more than a dozen requests made by Knox's lawyers, including a plea for new tests on key evidence that they believe would clear Knox and then boyfriend Raffaele Sollecito once and for all of the 2007 murder of Meredith Kercher,” reports CNN's Erin McLaughlin.
“The court did grant the defense's request for additional testing on a kitchen knife found in Sollecito's Perugia apartment, which they say had Knox's DNA on the handle and Kercher's DNA on the blade.”
Knox has always maintained her innocence in Kercher’s murder, telling CNN earlier this year, “I'm not responsible for what happened. I didn't do it. I wasn't there. I don't know anything more about it,”
“The court also said it would consider testimony of a convict named Luciano Aviello, a former cell mate of Sollecito's, who has claimed his own brother killed Kercher,” McLaughlin says.
But the proceedings did not bode well for the defense.
“It's always a bad day when the judge grants more of the prosecution's motions than the defense motions,” says CNN Legal Analyst Danny Cevallos.
McLaughlin reports, “While Knox remains in the United States, her lawyers furiously argued on her behalf, warning of the risk of an ‘infinite trial’ since a murder charge in Italy has no statute of limitations.”
“If she is ultimately convicted, she will be ordered to return to Italy. If she refuses, Italy could ask for extradition from the United States.”
