The unidentified woman that made off with more than $13,000 worth of jewelry during an armed robbery at North Georgia Premium Outlets last month is now being considered a suspect in at least three other jewelry store heists.

"In all [the] cases, the woman has the same M.O. She comes in early in the morning, forces the employees to the back of the store and zip-ties their hands," said Dawson County Sheriff's Maj. Ray Goodie.

No one was injured in the Aug. 5 robbery of the Zales Outlet in Dawsonville, though the woman did brandish a handgun when she entered the store just after 10 a.m.

Less than a week later, a jewelry store in Panama City Beach, Fla. was held up by a woman who was able to escape with more than $400,000 in jewelry, according to authorities.

In the latest incident, a woman fitting similar description hit a jewelry store in Bluffton, S.C.

An FBI press release on Tuesday calls the white woman, who has been seen with a black male, suspect in all three capers, as well as in a jewelry heist at a store in Woodstock back in April.

Each of the "robberies mirrored the Panama City Beach robbery and the suspects appear to be of the same build in reviewed surveillance video," according to the FBI Jacksonville office.

Authorities believe the woman is in 20s, approximately 5'8" tall and 130 pounds. The black male suspect is described in his late 30s to early 40s, about 6' tall and 250 pounds.

Surveillance photos appear to show the suspects' vehicle as a red 2009-2010 Honda Civic LX with tinted windows.

They are considered armed and dangerous.

The Jewelers' Security Alliance is offering a reward of up to $10,000 for information leading to the arrest of the female robbery suspect.

Anyone with information is asked to call the FBI Jacksonville Field Office at (904) 248-7000. The reward hotline can be reached at (800) 325-1883.
