A third man has been indicted in connection with the September kidnapping of a Clayton County teenager, federal authorities said.

Christopher Joseph Atkins is wanted by the FBI for his alleged role in kidnapping Ayvani Hope Perez, 14, during a home invasion in the predawn hours of Sept. 17.

And federal authorities are asking for the public’s help to find the 19-year-old Atkins.

Wildrego Jackson and Tony Graves were arrested and are in federal custody on kidnapping and other charges in connection with the incident.

On the morning of Sept. 17, authorities said two armed men pried open the back door of the home near Ellenwood where Perez lived with her younger brother, their mother and her boyfriend, authorities said.

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.
