Famed parenting author and motivational speaker Kristine Barnett and her ex-husband, Michael Barnett, have been charged with the neglect of their 11-year-old daughter Natalia, whom the couple left to fend for herself in an apartment. But according to a new report, Kristine thinks Natalia, who was adopted from the Ukraine in 2010, was actually 22 when she lived with them. She claims her adoptive daughter is a mentally disturbed adult posing as a little girl, and that she threatened to kill them.

As the Daily Mail, points out, the case mirrors the plot of 2009 horror film Orphan, starring Isabelle Fuhrman as adopted orphan Esther, who attempts to murder her family when it’s revealed that she’s actually 33.

Here’s everything you need to know about this stranger-than-fiction case.

Kristine Barnett was famous for her parenting skills

Author of “The Spark: a Mother’s Story of Nurturing, Genius, and Autism,” Kristine was praised for raising her “genius” physics prodigy son, Jake, who was diagnosed with autism at the age of two. Jake’s first academic paper was published at 12, and he later enrolled as an undergraduate student at Purdue University. Kristine and then-husband Michael were featured in a “60 Minutes” report in 2012 highlighting Jacob’s successes. (You can see Natalia appear onscreen next to Kristine in the above video at the 1:37 mark).

A critic for The Washington Post, called the book “compulsive reading,” and adding that, “Barnett not only fights heroically on Jake’s behalf, she also beats down every other obstacle that life hurls at her and her family.” Kristine’s author page on Penguin Random House says that she, “lives in Canada with her husband, Michael, and their three boys, Jacob, Wesley, and Ethan. She is a public speaker on alternative education for children with autism.”

Michael and Kristine Barnett adopted Natalia in 2010

Kristine and Michael reportedly adopted Natalia, who has a form of dwarfism called spondyloepiphyseal, two years after she came to the U.S. from the Ukraine through an adoption program in 2008, according to court documents obtained by several news outlets, including WLFI News 18, ABC 7 Chicago and Fox 59. They were told Natalia was 6 years old.

They all lived together in what The Washington Post describes as a “cozy suburban home north of Indianapolis.”

Kristine claims Natalia threatened her family with violence

Speaking exclusively to the Daily Mail (which obtained purported photos of Natalia), Kristine says her and her family were terrorized by the girl for years. “She would make statements and draw pictures saying she wanted to kill family members, roll them up in a blanket and put them in the backyard,” Kristine told DailyMailTV. “She was standing over people in the middle of the night. You couldn’t go to sleep. We had to hide all the sharp objects.”

“I saw her putting chemicals, bleach, Windex something like that, in my coffee and I asked her, what are you doing? She said, ‘I am trying to poison you,'” adds Kristine. “The media is painting me to be a child abuser but there is no child here.”

Kristine goes on to tell DailyMailTV that Natalia was “a woman, she had periods, she had adult teeth,” and that she “never grew a single inch, which would happen even with a child with dwarfism.”

“The doctors all confirmed she was suffering a severe psychological illness only diagnosed in adults,” she said. “She was jumping out of moving cars. She was smearing blood on mirrors. She was doing things you could never imagine a little child doing.”

Kristine and Michael legally changed Natalia’s age to 22 in 2012

Kristine claims she became suspicious of Natalia’s age the first time she gave her a bath. “I noticed that she had full pubic hair. I was so shocked. I had just been told she was a six year old and it was very apparent she wasn’t,” she told the DailyMail. According to the outlet, there were other signs that Natalia was older—and perhaps not even from the Ukraine:

Natalia shunned dolls and toys, sought the company of teenage girls and appeared to use sophisticated vocabulary way beyond someone her age. She didn’t have any trace of a foreign accent and when the family asked a Ukrainian friend to speak in their native language Natalia couldn’t understand or describe her homeland.

However, according to The Washington Post, Natalia’s doctors determined she was likely 11 in 2012. But that same year, Kristine and Michael were somehow able to change her age to 22 by going to an Indiana probate court. The outlet reports:

Officials haven’t yet explained how they were able to do so, but Kristine Barnett gave WISH-TV a copy of a letter that purportedly came from another doctor who said that the date on the girl’s birth certificate was “clearly inaccurate,” since she had both the teeth and the secondary sex characteristics of a grown adult.

The station wasn’t able to confirm the authenticity of the letter, which alleges the girl “has made a career of perpetuating her age facade,” since hospital officials declined to comment. The same document also claims the girl had been committed to a psychiatric hospital and diagnosed with sociopathic personality disorder in 2012 and, around that time, started to admit that she was over 18. Determining her true age was difficult, the letter states, because records provided by Ukrainian officials were “grossly incomplete” and her condition, spondyloepiphyseal dysplasia congenita, meant that the typical assessments weren’t helpful.

Michael reportedly told police a different story

According to The Washington Post, when interviewed by detectives, Michael said they knew Natalia was a minor when they changed her age to 22. He also that Kristine coached Natalia to tell people that she just looked young.

Kristine and Michael abandoned Natalia in an apartment in 2013

According to a probable cause affidavit obtained by NBC News, police first became involved in the case around September 2014 when Natalia told authorities the Barnetts rented her an apartment in Lafayette. Then, she says, they moved to Canada. According to WLFI, Kristine and Michael admitted earlier this month that they didn’t financially support Natalia other than paying rent, after leaving her in the apartment. According t0 court documents obtained by WISH-TV, Natalia was evicted for not paying rent in 2014, less than a year after she was left her alone.

Seven months after moving to Canada, Michael and Kristine filed for divorce, according to WISH-TV.

Five years later, Kristine and Michael were charged with neglect

It remains unclear what happened between 2014 and now—but just two weeks ago, the ex-couple were charged with two counts of felony neglect of a dependent. According to the DailyMail, Kristine surrendered to authorities on Thursday and was released after posting a $5,500 bond. Michael also surrendered and was released after posting $5,000 bail.

Kristine has posted a Facebook status about her case, writing: “I am sick and devastated from the idea of any of these charges and maintain that they are false charges.”

Where is Natalia now?

According to several local news outlets, attempts to track down Natalia have been unsuccessful.
