SAN JOSE, Calif. (AP) - A Nevada couple pleaded guilty Friday to all charges related to planting a human finger in a bowl of Wendy's chili in a scheme to extort money from the fast food restaurant chain.

Anna Ayala, 39, and Jaime Placencia, 43, pleaded guilty to conspiring to file a false claim and attempted grand theft in a scheme that the Dublin, Ohio-based Wendy's International Inc. claimed cost it $2.5 million in lost sales because of bad publicity.

Ayala's attorney, Rick Ehler, said she was truly remorseful.

Wendy's President and Chief Executive Officer Tom Mueller said he hoped the guilty pleas would "send a strong message and serve as a deterrent to others who may contemplate a fraudulent crime against the restaurant industry."

Ayala faces up to nearly 10 years in state prison when sentenced Nov. 2. Her husband faces up to 13 years behind bars.
