Amanda Knox's now ex-boyfriend, Raffaele Sollecito, released a book revealing his spiral romance with Knox, maintaining their innocence in the murder of British student Meredith Kercher, Knox's roommate, and also admitting how they both behaved "oddly" immediately following Kercher's death. "Honor Bound: My Journey to Hell and Back with Amanda Knox" states the couple's innocence in the case but reveals their somewhat "bizarre behavior" that may have given police reason to suspect their involvement in the crime, according to Daily Mail. After arrest, Knox reportedly did splits and cartwheels in the police station and sat on Sollecito's lap during her police interrogation, the site reported. The memoir also revealed that Knox and Sollecito smoked marijuana the night Kercher was killed.
