Just when you thought Foxy Knoxy was as guilty as sin, up pops a friggin Mafia dude claiming his brother was the killer all along. Luciano Aviello, who is currently serving 17 years in prison, is adamant it was his brother who killed Meredith Kercher and not Amanda Knox. And whats more, he says he has the evidence to prove it. Luciano claims his brother Antonio turned up unexpectedly at his house the night of the murder covered in blood. He told him he had bungled a burglary and killed a woman. Luciano then hid the bloody knife and the keys to Kercher and Knox’s apartment under a little wall behind his house. Despite writing several letters to the presiding judge during the trial his story was never investigated.
