The crimes happened back on February 8th and February 15th at the Panera Bread store on East Main Street.
Investigators say two different victims reported their wallets and credit cards stolen while they were at the store.
The cards were later used at the Christiana Mall.
In the months since the theft, police say they have been unable to identify a suspect who was caught on surveillance camera.
Anyone with information on the woman's identity is asked to call Cpl. Robert Vernon at 302-366-7110 ext. 452 or Robert.firstname.lastname@example.org.
