DUNN, N.C. — She's cool, she's calm, and police say she's robbed three banks in two weeks. Authorities from Johnston County and Wilmington are on the lookout for a female bank robber, and they need your help.

The woman that police are seeking is quiet, composed and casual. But police say her message to bank tellers is a menacing threat.

"She'll go into the bank, pass the teller a note asking for a specific amount of cash, and then she takes back the note, gets the money and walks out very calmly," said Benson Police Lt. Randy Beasley.

Like a shadow, she slips in and out in broad daylight, striking first at a BB&T in Benson.

"You rarely see a female go it alone," said Beasley.

Police describe the woman as a "fly by the seat of her pants" kind of robber. Either that, or she's extremely brazen, because the bank she robbed in Benson is right across the street from the police department.

She then drove 90 miles east to Wilmington and robbed a First Citizens Bank before heading back west to hold up a bank in Dunn, this time wearing an N.C. State baseball cap.

The female robber is described as being in her late 20s to early 30s, with a small build. Investigators are banking on surveillance photos to turn up some fresh leads.
