Knox Beau: We Were Odd, But Innocent

Amanda Knox's former boyfriend admits they were a crazy couple who exhibited bizarre behavior after Knox's roommate was killed, but that doesn't make them murderers. The two were charged with killing Meredith Kercher in Knox's Italian apartment in 2007 during what cops described as a drug-fueled sex rampage. They were acquitted last year on appeal. Raffaele Sollecito said that he and Amanda made out at the death scene while police investigated, and they were caught smooching on TV cameras across the street. Knox, who was an exchange student at the time from Seattle, also shopped for underwear after the killing and turned cartwheels in front of police, Sollecito writes in his new book, Honor Bound, which was obtained by AP. At the police station during questioning, Knox climbed in Sollecito's lap, which he said made him uneasy.

Police found their behavior "odd," which made them suspicious, writes Sollecito. He also acknowledges they had no "real alibi the night" of the murder— "except each other." The appellate court found there was no evidence to support the prosecution's case. Prosecutors, however, have appealed the couple's acquittal, and Italy's highest court will hear their arguments in spring. The only person who remains in prison for the murder is petty criminal Rudy Guede. Knox is also writing a book about the case in a $4 million deal with HarperCollins. (More Meredith Kercher stories.)
