ROSWELL, Ga. -- Court documents reveal new details in the murders of two teenagers behind a Publix in Roswell.

Natalie Henderson and Carter Davis, both 17, were found dead behind the grocery store on Woodstock Road in the early morning hours of August 1. They had each died of a single gunshot wound, according to the medical examiner.

Police have arrested 20-year-old Jeffrey Hazelwood in the deaths. He's facing eight charges, including murder.

According to arrest warrants, police believe Hazelwood followed the teens behind the Publix before shooting them.

Arrest warrants also allege that Hazelwood took Henderson's wallet after shooting her, and then used her debit card at a Flash Foods gas station seven miles away from the Publix. The manager of the store told 11Alive that she provided surveillance footage from that night to police.

Hazelwood also stole jumper cables from Davis' car after the murders, the warrants indicate.

Police said that Hazelwood's cell phone has provided key information in the case.

Authorities have not speculated on the relationship between the three, or said why they were behind the grocery store. They have also not released a motive in the killings.

Wearing a wedding ring and shaking heavily, Hazelwood waived his first court appearance on Friday. He'll be back in court later this month. He's being held at Fulton County Jail.
