The gunmen demanded money and jewelry, then fatally shot the family dog before taking Perez.
Hours later, Atkins, Graves and Jackson repeatedly called Perez’s family demanding ransom money and drugs in exchange for her safe return, according to the federal indictment.
Perez was dropped off on Sept. 18 at a relative’s home in Conyers, police said.
Federal agents arrested Jackson within hours of Perez’s return while he was going to a Fulton County court hearing for unrelated charges, authorities said.
Jackson named Graves as one of his cohorts and FBI agents arrested Graves on Oct. 11.
Atkins remains at large.
Jail records show he was arrested twice in 2012 in Fulton County – once by Georgia State University Police – for snatching theft charges.
An arrest warrant was issued last month for Atkins’ arrest and the FBI asks that anyone with information about his whereabouts call 404-679-9000.
