The New York Post reports that Silling A. Man, a Georgia State student, was discovered in the vacant fast-food restaurant at Gwinnett Place Mall in Atlanta.
Officials believe that Man was dead two week prior to being found at the Duluth mall.
According to authorities, Man went missing again two days later, and would not be found again until her body was discovered. One spokesperson said law enforcement's "main goal" was to "identify her and then begin looking into her past, people she associated with and the timeline leading up to the discovery of her body". She had not enrolled for the spring semester.
A sketch provided by county detectives led to an aunt of Man's drawing a connection between the story and her missing niecing, according to WSBTV.
Investigators said the death has not been ruled a homicide, but added in a press release that "the circumstances surrounding her death are still being investigated". She was dressed in a black, mesh-style jumpsuit, police said.
She was previously reported missing in October by a family member, but returned home shortly after.More news: Why young, healthy people are dying from the flu this season

Man's body was first discovered December 21 around 11 a.m. EST by a mall maintenance staff during a routine check.
"What's suspicious about this case is the cause of death has not been determined".
She has since been identified as Silling A. Man.
There were no surveillance cameras in the mall corridors at the time, police said. Police urged anyone with information regarding her activities from mid-October to mid-December to come forward.
Those who can help are asked to call 770 513-5300.
"It's probably not a great reflection of the current private owners of the mall", Jace Brooks, a local county commissioner, told an Atlanta Journal-Constitution columnist.
