Police say the suspect accused of killing two teenagers near Atlanta stole the girl's wallet and the boy's car jumper cables after he killed both with gunshots to the head.
The details are contained in arrest warrants filed in the municipal court of Roswell.
The warrants say 20-year-old Jeffrey Hazelwood followed 17-year-olds Natalie Henderson and Carter Davis into an alley behind a Publix grocery store before shooting each teenager once in the head Aug. 1.
Hazelwood is charged with murder and theft. Police have declined to discuss a possible motive for the slayings.
Hazelwood's attorney, Lawrence Zimmerman, has said he will provide a vigorous defense.
Henderson and Davis, who used to live in Rapid City, South Dakota, would have been high school seniors this year.
A February 2015 report released by Roswell police lists Hazelwood as a suspect in the gun theft from his grandfather's house, where Hazelwood lived with his grandparents in Roswell.
Police released another report of officers called to the same home in 2013 in which Hazelwood's grandparents said their grandson, then 16, stole a sword and knives from their gun safe. That report, which doesn't identify the teen by name, says he'd told his grandmother that "he was going to blow and people were going to get hurt."
