The 20-year-old man accused of killing two teenagers behind a Roswell grocery store has been indicted on 15 counts, including murder, aggravated assault and sexual battery, according to a Fulton County indictment released Monday.

Jeffrey Hazelwood is accused of shooting and killing Natalie Henderson and Carter Davis, both 17, in the early-morning hours Aug. 1, according to police. On Friday, a grand jury indicted Hazelwood on charges of murder, felony murder, aggravated assault with a deadly weapon, kidnapping, aggravated assault with a deadly weapon, kidnapping, aggravated sexual battery, financial transaction card theft, identify fraud, theft by taking and possession of a firearm during the commission of a felony.

Around 3 a.m. Aug.1, Hazelwood told police he watched the teenagers for about 20 minutes before he opened the back door of Henderson’s SUV with one hand while holding a gun with the other. Hazelwood first shot and killed Davis, he said, before he told police he sexually assaulted Henderson, then shot and killed her.

After the shootings, Hazelwood left the scene and then returned to steal Henderson’s bank card, which he later used, and jumper cables belonging to Davis, according to police.

Shortly after 6 a.m., a delivery driver came upon the bodies of the teenagers, lying on their backs on the pavement, and called 911. Officers arrived within minutes, and the investigation into the double homicide began. That morning, Davis was supposed to start his senior year at River Ridge High School and Henderson was to start 12th grade at Roswell High School the following week.

Local and state investigators worked quickly to identify a suspect, based on his physical description, surveillance footage and vehicle ownership records. Within 48 hours, Hazelwood was taken into custody and charged with two counts of murder. He has remained in custody without bond since his arrest Aug. 3.

In hours of interviews with investigators, Hazelwood explained what he did to the teenagers, but never offered a motive

District Attorney Paul Howard has not said whether he plans to seek the death penalty.
