A Thessaloniki computer student was jailed yesterday for 12 years and four months for the 2002 fatal stabbing of her brother-in-law, who she claimed had been sexually abusing her since her early teens. A court in the northern town of Katerini accepted that Natalia Kankova, 22, an immigrant from the former Soviet Union, had killed Giorgos Kehiopoulos, an ethnic Greek and former Red Army officer, in the heat of the moment. Hours after the March 11 killing, Kankova confessed to stabbing her brother-in-law with a kitchen knife in the Aristotelous Square office they shared, but told police Kehiopoulos had been forcing her to have sex with him since she was 14. She claimed to have stabbed him after he attacked her when she begged him to leave her alone. Initially, Kankova had said she was Kehiopoulos’s daughter, having been registered as such as part of an immigration scam.
