Knox claims police beat her during murder probe
Amanda Knox also repeated that she spent the night of the killing at the house of her co-defendant and ex-boyfriend Raffaele Sollecito, in Perugia, central Italy.
Prosecutors contend that Knox, an exchange student from Seattle, and Sollecito killed 21-year-old Meredith Kercher on November 2, 2007, in the apartment she shared with Knox during what began as a sex game.
