And she is awfully good at altering her look. She is believed to be in her 20s. She changes her clothing and oversized dark glasses, she's about 5 feet tall and 140 pounds.
Yesterday, on opening day, she was sporting a Phillies cap. She robs with a demand note, but has not shown a gun.
"The note implies she has one, but she has never displayed a weapon," said Delaware State Police Corporal Jeffrey Hale.
She has hit three times. Thursday it was at a WSFS branch inside a Shop Rite on West Newport Pike in Stanton, Del. Prior to that she hit a Citizens Bank/Acme combo on Limestone Road in Pike Creek not once but twice in about ten days.
Why the supermarket branches? One theory her "covered up look" would draw less attention in a busy store than in a standalone branch.
Outside the Citizens branch Friday, people reacted to news of the female bank robber.
"Times are tough," said Dave Winward of Wilmington. "I guess she needs the money if she walks into same supermarket twice to get some cash.
Female bank robbers are a rarity despite some legendary ones like the female half of an infamous 1930's duo.
"Like Bonnie and Clyde, but she seems to work alone," said Connie Sansone of Wilmington. "You never expect a female bank robber."
But there she is behind the disguises.
