Nuoro, November 8 - A retired road inspector was allegedly killed by his neighbour with three gunshots at close range near the Sardinian city of Nuoro on Friday, police said. Antonio Longu, 71, was killed midmorning in the yard of his home in the village of Lula. The prime suspect is the victim's neighbour, 74-year-old Mario Farris, who is being closely guarded in a Nuoro hospital after suffering a sudden illness. Longu and Farris lived in the same two-storey tenement block in Via Dei Mille. It is thought the pair had a row over a TV antenna shortly before the murder. Farris served over 20 years in prison for murdering his pregnant wife and throwing her body in a river in Germany in 1974. He returned to Lula after his release. The last murder in Lula took place a year ago, when animal breeder Angelo Maria Piras, 40, was shot dead with a rifle on his farm. His brother and his brother's wife were arrested for the crime in November.
