Woman who confessed to kidnapping prank takes lie detector test in revealing new book

Coming clean hasn’t been easy for Sherri Papini.

The California mother of two was given an 18-month prison sentence in 2022 for fabricating her own kidnapping to rekindle a relationship with an ex-boyfriend. Her vanishing act led to a three-week search across multiple states until she resurfaced on Thanksgiving Day in 2016.

Now, at the age of 42, she is revisiting her disappearance and undergoing a polygraph test on the show “Sherri Papini: Caught in a Lie” on Investigation Discovery (ID).

During the show, Papini revealed that she engaged in an emotional extramarital relationship with Reyes due to her dissatisfaction with her marriage and the fear of losing custody of her children. However, she maintains that the kidnapping was not staged. The discovery of Reyes’ DNA on the clothing she wore when she was found supports her version of events.

Rittenmeyer said this is the first time Papini is publicly sharing this account.

Monica De La Mora, or “Mo,” spoke about what it was like being behind bars with Sherri Papini. (ID)

“She never shared it with anyone except for us and very close members of her family,” said Rittenmeyer. “This is going to be the first time Shasta County sheriffs will hear this story when they watch it with the rest of the viewers.”

Fox News Digital reached out to the Shasta County Sheriff’s Office, Keith’s attorney and Reyes for comment. According to the docuseries, Reyes vehemently denies kidnapping and abusing Papini.

“He maintains that any harm he inflicted on her was done at her direction,” the docuseries shared. “He has not been charged with any crime in connection with Sherri’s disappearance.”

When questioned by FBI agents, Reyes claimed that Papini planned “everything,” including the decision to use a wood-burning tool to brand her shoulder. He passed a polygraph test.

“What I learned… is that her particular form of personality disorder results in a lot of pleasing,” Rittenmeyer continued. “There’s an effort to please, which served us well when we did reenactments and the polygraph because she didn’t want to do those things, but she did them.

Attorney Bill Portanova represented Sherri Papini and spoke about his famous client in the docuseries. (ID)

“… We assume people lie because they’re trying to deceive because there’s financial gain or something that they’re trying to get over on us. And in the case of her personality disorder, she lies as a protective mechanism. It’s like default. She’s gotten a lot of therapy, and she’s a lot better than she used to be. But… there was so much more nuance to her and why she did the things that she did, and what drove her to do them.”

In 2022, Papini accepted a plea bargain with prosecutors and acknowledged she made up the story that prompted the frantic search. That same year, Keith filed for divorce.

“I am deeply ashamed of myself for my behavior and so very sorry for the pain I’ve caused my family, my friends, all the good people who needlessly suffered because of my story, and those who worked so hard to try to help me,” she said in a statement at the time. “I will work the rest of my life to make amends for what I have done.”

The plea agreement called for Papini to pay restitution topping $300,000.

Rittemeyer said that Papini, now out with her story, is “working on being a better person.”

“I do think the person I interviewed is very different from the one… Shasta County interviewed,” said Rittenmeyer. “She went through it. She served her time. She’s done a lot of therapy… If there’s a lesson to take away from this film, I think it’s don’t lie. You kickstart events and you’re going to spiral horrifically out of control.”
