Jeffrey A. Hazelwood appeared before a Fulton County Superior Court judge for his arraignment Thursday, FOX 5 reports.
The 20-year-old was arrested on Aug. 3 and charged with two counts of murder in the deaths of Carter Davis and Natalie Henderson, both 17.
Both were fatally shot in the head at close range on Aug. 1 behind a Publix supermarket in Roswell, hours before they were found by delivery truck drivers at 6 a.m., police said. Henderson’s body was found in a pool of blood and had been stripped naked and posed in a sexually suggestive manner, according to an autopsy report obtained by PEOPLE.

At a court hearing, police said Hazelwood allegedly confessed to the crime, saying he had acted alone. Cell phone records confirm Hazelwood was in the area when the crime was committed, police have said.
Police allege Hazelwood tortured Henderson, forcing her to stand nude with her hands on the hood of Davis’ car while he spanked her buttocks. He also sexually assaulted her with his finger, according to police.
Hazelwood was arrested 48 hours after the alleged murder. In a search of Hazelwood’s room at his grandparents’ home, police allegedly found drawings and writings expressing his desire to be “an assassin.”
When questioned by police, Hazelwood’s grandparents said they were afraid of their grandson.
It is unclear when Hazelwood is scheduled to make his next court appearance. His attorney, Kenneth Schatten, did not return PEOPLE’s calls seeking comment.
