The Las Vegas couple accused of planting a piece of human finger in a bowl of Wendy's chili pleaded guilty Friday in a San Jose courtroom.

Anna Ayala, 39, and her husband, Jaime Placencia, 43, pleaded guilty to all charges without any conditions in Santa Clara County Superior Court.

Coming into the hearing, Ayala was facing a maximum possible sentence of nine years and eight months in prison. Placencia has been facing more than 13 years in prison but he has additional, unrelated charges against him for allegedly failing to pay child support.

The couple allegedly sought to swindle money out of the fast food chain by planting a piece of human finger in a bowl of chili that Ayala ordered at the Wendy's on Monterey Road in San Jose on March 22.

Authorities focused on the couple after learning that they had filed multiple lawsuits seeking money from big businesses prior to the Wendy's incident. Investigators ultimately traced the piece of finger to a former co-worker of Placencia's who claims to have sold it to him.
