20-Year-Old Man Arrested in Connection With Deaths of 2 Georgia Teens, Police Say

— -- A 20-year-old man has been arrested and charged in connection with the shooting deaths of two teenagers in Roswell, Georgia.

The suspect, Roswell resident Jeffrey A. Hazelwood, was arrested and charged with two counts of murder around 5:00 this morning, said Roswell Police Chief Rusty Grant. Hazelwood was being held at the Roswell Detention Center and was expected to be transferred to the Fulton County Jail.

Police believe Hazelwood acted alone but were unable to comment on any motive or statements he may have given to police, Grant said. It is unclear whether Hazelwood had a criminal record or knew the victims, Grant said.

Detectives located Hazelwood Tuesday night at a gas station in the area, said Roswell Police Detective Zachary Frommer.

The victims, Natalie Henderson and Carter Davis, both 17, were found dead by a delivery driver behind a Publix supermarket in Roswell shortly before 6 a.m. Monday, the Roswell Police Department said. Detectives were reviewing surveillance video to look for witnesses and follow up on leads.

After the autopsies were performed, the Fulton County medical examiner said Henderson and Davis each died from a single gunshot wound to the head and ruled that both deaths were homicides.

Henderson was a rising senior at Roswell High School and was described by her mother as "whip-smart, funny, sassy and strong." Davis was a senior at River Ridge High School, where he played football and lacrosse and "excelled in the classroom and was always willing to help out classmates," the school's principal, C. Darrell Herring, wrote in a letter to parents Monday.

Publix spokeswoman Brenda Reid told ABC News that the company could not comment on an open investigation but said, "Our prayers and thoughts are with the family members of those two young people. We just pray for their peace of mind and recovery."
