Georgia police are investigating the slayings of a boy and girl, both 17, found dead behind a supermarket in Roswell on Monday, PEOPLE confirms.
Natalie Henderson and Carter Davis were both found with fatal gunshot wounds to the head behind a Publix supermarket just before 6 a.m., Zachary Frommer, with the Roswell Police Department, tells PEOPLE. The manner of death for both teens is homicide, according to a police statement obtained by PEOPLE.
Frommer says delivery drivers found the teens’ bodies near two vehicles behind the supermarket in the tony Atlanta suburb.
“Early indications are that they were killed there. We don’t really have reason to believe they were killed elsewhere,” Frommer told the Associated Press.
Investigators are reviewing surveillance footage of the area and searching for witnesses in the shooting, Frommer tells PEOPLE.
“Drugs were not involved,” Frommer says. He adds, “It could be some kind of relationship-based situation. It may end up not being that. That was just an initial, quick assessment.”

No arrests have been made in the case, there are no suspects and police have not determined a motive for the killings, Frommer says.
Police executed a search warrant at a home in Cobb County, near Roswell, at around 8 a.m. on Wednesday, Frommer tells PEOPLE.
“We are not going to go into who lives there or how it may be related other than to say that it is not the residence of either of the victims,” he says.
He adds that things are “moving well” in the investigation, noting that there are several leads.
“We have a number of people that we have spoken to, a lot of potential evidence we have gathered and a lot of surveillance video that we have reviewed,” Frommer tells PEOPLE.
He declined to say what investigators learned from the surveillance footage.
In a statement to PEOPLE, Publix said it “sends our thoughts and prayers up for the families of the those affected by this tragic loss of life.
“We are cooperating with the Roswell Police; however, we cannot comment on the case because this is an open investigation.”
Both Davis and Henderson were entering their senior year of high school – she at Roswell High School and he at River Ridge High School, according to the police statement.
Frommer describes the pair as “friends.”
“Not saying they were or were not in a relationship,” he says. “We aren’t getting involved in defining their relationship so we will just say they were friends.”
Monday morning would have been Davis’ first day of school.
Roswell High School’s band director, Michael Moon, remembered Henderson in a statement posted Monday to the band’s Facebook page.
“Natalie Henderson was a thriving member of the Color Guard – a fun, smart, talented young woman who was loved by so many,” he said in the statement. “Her absence will be felt by each of us tomorrow and for a long time to come.”
In a Facebook post, officials with River Ridge High School’s lacrosse team uploaded a photo of Davis.
“Our Knights family is in mourning over the loss of our own Carter Davis,” the post read.
