DeKalb County Police Chief William O'Brien said 46-year-old Dennis Ronald Allaben, of Tucker, visited relatives in Virginia and told them about the murder before driving two days to Clayton County and turning himself in.
O'Brien said Wednesday that police recovered the body of 43-year-old Maureen Allaben from the truck bed. He said no signs of struggle or other evidence of a murder was found at the couple's home.
Allaben was booked into the DeKalb County Jail on felony murder charges Tuesday.
O'Brien could not say why Allaben killed his wife, who had worked as a commercial photographer.
