When undercover federal agents visited Aunty Florence's West African Market in Darby in 2010, they found the owner willing to illegally exchange food-stamp benefits for cash.
Florence Kingsley, 59, of Darby, pleaded guilty Wednesday in federal district court to food-stamp fraud.
A Liberian national, Kingsley fled that country in 1992 amid a civil war and was given asylum here. In 2007, she opened a small food store and sold spices, fruits, vegetables and meats.
The feds became suspicious of Kingsley after she sought monthly payment for authorized food-stamp sales greater than the annual $80,000 estimate she gave in a 2008 application to participate in the program.
