Police searched a Central Ohio home Thursday for clues in the death of a pregnant woman found in a car parked along a Delaware County road on Wednesday. Authorities did not say if they found anything linked to the case of 23-year-old Deanna Ballman of Pataskala, who was last seen on Tuesday. The Colorado Army National Guard says Ballman was a supply specialist with the 220th Military Police unit and was transferring to a unit in Ohio.
