A real estate agent, presumed murdered, was found dead inside a vacant home near Kent, Ohio, early Tuesday. His death follows another agent who was found murdered on Monday in Youngstown, Ohio. The wife of Cutler Realty agent Andrew VonStein, 51, notified the sheriff shortly before 4 a.m. that her husband was missing. She also called the car's OnStar service, which in turn called the car, but did not get a response, according to news reports. Tracking the vehicle through the OnStar GPS system, deputies found the car in the driveway of the vacant home. In Youngstown where the owner of Essence Realty was discovered on the kitchen floor in a burning home on Monday, police are treating the death of 67-year-old Vivian Martin as a homicide. She had gone there to meet a client. It was originally thought that the home burned due to a gas explosion, but WFMJ-TV reported that the gas to the vacant home was shut off and thus not the cause.
