On March 22, 2005, Anna Ayala claimed she found a finger in a bowl of chili at a San Jose Wendy’s restaurant. The finger became the talk of the Internet and late-night talk shows, spawned numerous bizarre tips and theories about the source of the finger, and led to dozens of copycat claims. Wendy’s lost tens of millions of dollars.

Turns out the finger belonged to a co-worker of Ayala’s husband who severed it during a construction accident and was planted in the chili in a misguided attempt to extort money from Wendy’s.

In Jan. 2006, Ayala, 40, was sentenced to nine years; the hubby got more than 12 years.

Two days ago, police in York, Pennsylvania, charged Shelby Lyn Adams, 40 (righ, exactly as shown), of York, with killing her 90-year-old grandmother, Ada Adams, by poisoning her Wendy's chili with morphine three years ago in York Township.

The investigation lasted about three years -- set back by the lengthy gathering of scientific evidence and a change in investigators because of a promotion in 2010, said Chief Thomas Gross with York Area Regional Police.

"The detectives did a thorough job at the scene, which was difficult
considering the death of a 90-year-old woman with no real evidence of a disturbance," Gross said Thursday afternoon.

Police also had to wait on autopsy and forensic results from vomit on Ada Adams' blouse, which showed the plant substances found in Wendy's chili, according to court documents.

Gross said that suspicious family members were "very persistent in getting justice for their mother."
