Julia Faustyna who claims she may be missing UK girl Madeleine McCann may have cancer

The woman who submitted a DNA test in the hope it would prove she’s missing British girl Madeleine McCann has been dealt crushing news.

A Polish woman who claims she could be missing British girl Madeleine McCann may have cancer.

Julia Faustyna, who also goes by the name Julia Wendell, stunned the world when she took to social media to reveal her belief that she may be the missing four-year-old girl.

Madeleine disappeared from her family’s holiday resort in Portugal in 2007.Faustyna, 21, had submitted samples for three different forensic examinations that will outline her DNA sequence, along with a 23andMe-style genetic test to establish her ancestry.

But her spokesman has revealed Ms Wendell may be battling leukaemia as she awaits test results back.

Julia Faustyna is a 21-year-old aspiring musician and model.

“We are still waiting on the result of DNA testing that will show us exactly what Julia’s ethnic background is and what country she and her true family are from. These kinds of tests are very accurate,” Ms Wendell’s representative and private detective Dr Fia Johansson told The Sun.

“Of course depending on the result of that we will continue our investigation to see if Julia could be Madeleine or another missing person.

“She has had a neglected childhood and suffered much abuse. Her health is very poor she has bad asthma and she suffers lots of pain in her bones. She is booked in for a CT and MRI scan because of the pain in her bones.

“Her blood work is also abnormal so my doctor here in the US is investigating whether she could have leukaemia so we are awaiting the results of that. And if she needs any treatment we will make sure she gets that.”

The woman has reportedly moved due to death threats.

If Ms Wendell’s ancestry comes from the same region as Madeleine’s parents, Gerry and Kate McCann, Dr Johansson said she will immediately send the DNA sequence to Portuguese investigators for comparison.

“If the results come back that she’s British or from that area then we are going to continue our investigation into Madeleine McCann and communicate with the detectives in Portugal,” said Dr Johansson, who this month revealed she had moved Ms Wendell from Poland to a safe house in the US after a series of death threats.

“We have a lot of evidence right now that shows Julia was definitely trafficked to Poland from another country by an international sex trafficking group.

“We are still conducting an investigation but Julia is definitely not the biological daughter of her parents in Poland.”

Ms Faustyna alleges she has few memories of her early childhood and has never seen her birth certificate.

She claimed: “I don’t remember most of my childhood but my earliest memory is very strong and it’s about holidays in hot place where there was a beach and white or very light-coloured buildings with apartments.

“I don’t see my family in this memory.”

The Polish woman has documented apparent physical similarities between herself and Madeleine — including a distinct brown smudge on each girl’s right iris.

“I have similar eyes, shape of face, ears, lips, I had the gap between the teeth [as Madeleine],” she wrote in one post, with side-by-side photos of herself and the kidnapped child.

Ms Wendell’s family in Poland, meanwhile, have spoken of their “devastation” at her claims.

“For us as a family it is obvious that Julia is our daughter, granddaughter, sister, niece, cousin and step niece. We have memories, we have pictures,” the family said in a Facebook statement, via Polish missing persons organisation Missing Years Ago.

“Julia also has these photos, because she took them from the family home with the birth certificate, as well as numerous hospital discharges.

“We always tried to understand all situations that happened with Julia. Numerous therapies, medicines, psychologists and psychiatrists – Julia had it all guaranteed. She wasn’t left alone.

“Threats to our address from Julia, her lies and manipulations, activity on the internet. We’ve seen it all and we’ve tried to prevent it, to explain, we’ve asked her to stop.”

The family hinted at Ms Wendell’s motivations, writing that she “always wanted to be popular”.
