A missing Tennessee woman was found dead in the trunk of a car driven by her girlfriend — who killed herself after exchanging gunfire with cops in suburban Detroit. Eleni Kassa, 31, of Murfreesboro, was reported missing on Nov. 18 by her family after she failed to pick up her daughter from school, police in the Tennessee city said in a statement. A probe “revealed a possible domestic violence incident occurred with Kassa’s and her girlfriend, Dominique Hardwick, 36, following an argument at Kassa’s Murfreesboro apartment,” cops said.
