The prosecution said the fact that Knox falsely accused Lumumba of being the killer was a sign of her own guilt and an attempt to throw them off her trail. He was arrested in a dawn raid by armed police and spent two weeks in jail. It was only by chance that a Swiss businessman read about the case and came forward to say he had been talking to Lumumba in his bar on the night of the murder — offering him a rock-solid alibi. Lumumba says Knox nearly ruined his life and is suing her for defamation.
