A Lake Charles woman has pleaded guilty in federal court to defrauding the food stamps program.

Rosalyn Hilliard is one of three siblings who were arrested following an investigation into two of their convenience stores in Lake Charles.

Court documents show Hilliard and her brothers would allow customers to purchase ineligible items, such as alcohol and tobacco, with their food stamp cards.

Hilliard's brothers, Craig and Hillary Nash, had already pleaded guilty to similar charges. U.S. Attorney Stephanie Finley says more than $2 million was fraudulently obtained in the scheme.

Hilliard faces up to five years in prison and a fine of up to $250,000.
