A Greek policeman was found guilty of murder on Monday over the fatal shooting of a 15-year-old schoolboy nearly two years ago that sparked rioting across the country. Epaminondas Korkoneas, 38, was convicted of culpable homicide by a court in the town of Amfissa over the killing of Alexis Grigoropoulos during a December 2008 night patrol in the Athens district of Exarchia. The court will decide later Monday on the sentence of Korkoneas, who had pleaded not guilty. Prosecutors have asked for life in prison. The panel of three judges also found Korkoneas's patrol partner Vassilios Saraliotis, 32, guilty of complicity in the crime. The nine-month trial heard that Korkoneas fired three shots on December 6, 2008, in Exarchia, a district known as a hotspot for popular unrest. Korkoneas' lawyer, Alexis Kougias, said the incident was a tragic accident which arose as police fired warning shots to keep back youngsters who were hurling objects at them. An autopsy report indicated that the boy was hit by a bullet that ricocheted on to him but lawyers for his family highlighted testimony of witnesses who say the policeman took aim and fired. The December 2008 incident sparked days of rioting across Greece. A far-left extremist group threatened to kill Korkoneas, prompting authorities to relocate the trial from Athens to Amfissa, 200 kilometres (125 miles) northwest of capital, where it started in January.
