A Jefferson man has been arrested and charged in the death of a teenage girl and her unborn child, the Georgia Bureau of Investigation reported Friday.

An autopsy showed the death of Cheyanne N. Hair, 16, to be a homicide, the GBI said. The agency has not announced the cause of death, citing an active investigation.

The GBI on Friday arrested Jonathan Michael Smith, 34, of Winder Highway, Jefferson, and charged him with one count of murder and one count of feticide.

Smith and Hair had moved from Spalding County and were living at the Winder Highway residence where the GBI says Smith killed the teen, who was pregnant.

The GBI news release did not reveal the relationship between the two.

The Jackson County Sheriff’s Office and the GBI consulted with Piedmont Judicial Circuit District Attorney Brad Smith regarding the charges. Additional charges may be brought against Jonathan Smith as well.

Smith has been held in the Jackson County Jail since Wednesday on a probation warrant in Spalding County. It wasn’t known late Friday whether he has an attorney.

Hair died Wednesday at Athens Regional Medical Center after being transported from the Winder Highway location. A 911 call was received requesting medical service at the residence.

The Jefferson Police Department responded initially. The Jackson County Sheriff’s Office and GBI are conducting the investigation.
