Police said three children were in the house on a cold February morning when Konstantinos Koumboulis, 50, shot his wife, Georgia Koumboulis, 34, and then turned the gun on himself. The children were not physically harmed. According to the court decision, the Jaconos and their real estate agents, Re/Max, knew about the home's lurid history. They called the state Real Estate Commission who assured them that they were not required to disclose that information.
