The Delaware County Sheriff's Office says preliminary autopsy results on Deanna Ballman shows no signs of trauma to her body. The 23-year-old woman, of Pataskala, was last seen by family members Tuesday afternoon when they say she left to answer a job inquiry. Ballman's body was found in her car Wednesday on Bevelheimer Road in Westerville. Ballman was nine months pregnant when she died. Ballman's cause of death remains undetermined. A full autopsy with toxicology results is not expected for eight to ten weeks.
