The Delaware County Coroner say a young mother found dead in her car earlier this year died from acute heroin intoxication. The manner of death for 23-year-old Deanna Ballman has not been determined pending further investigation after an autopsy found no signs of trauma. Ballman lived in Pataskala and had been reported missing the day before her body was found in Harlem Township. Ballman's family says she said she was going to meet someone for a house cleaning job when she was last seen.
