Russell County sheriff's officials say the killings occurred Monday night near the small community of Hurtsboro.
The Russell County coroner identified them as 35-year-old Reginald Berry of Pittsview; and 27-year-old Michelle Denise Buchannon of Opelika.
Sheriff Heath Taylor tells The Columbus Ledger-Enquirer that both were shot multiple times. Their bodies were found slumped over in the car.
The sheriff said Berry was at a party earlier that night in Macon County, where a person was shot and wounded. Investigators suspect that suspects might have been seeking revenge against Berry or trying to eliminate witnesses from the earlier shooting.
