Authorities said the robberies took place on Dec. 27 -- one at about 5:30 p.m. at the Crown Fast Fare at 2516 S. Saunders St. and the second at about 9:30 p.m. at the Circle K at 2948 New Bern Ave.

Investigators say it is highly unusual for women to be charged with robbery and they hope video surveillance released to the media Thursday could help generate leads.

"I do not recall anything like this, so it's our hope that someone recognizes this young lady and has some information, and can pass it along to us," said Sgt. Stacey Deans.

Last year, there were 362 men charged in connection with armed robbery cases, but only 36 women -- "very few instances, especially in regard to handling or possessing a weapon and committing a commercial robbery like that," Deans said.
