The private investigator currently aiding the girl who believes that she is Madeleine McCann has revealed why she took the case, and it all came down to one "small detail".
The case of Julia Wendell - also known as Julia Faustyna or Julia Wandelt - has caused intrigue as she continues her journey to get to the bottom of her true identity as she believes she has been misled from an early age.
Julia, 21, grew up in Poland but took to social media claiming to be Madeleine McCann, a British girl who disappeared while on holiday in Portugal on May 3, 2007.
One aspect of the case that furthered the 21-year-olds claims that she was Madeleine was the similar physical features they both share.
The pair have a distinctive dark mark on their iris known as coloboma as well as a dimple on the left cheek.
It was these features that private investigator Dr. Fia Johansson noticed that convinced her to take the case, and the pair now reside together in the US after Julia fled Poland.
In an interview with Sky Australia, Dr. Fia revealed why she became involved with the case and wanted to help Julia in the search for her true identity.
"At this moment, the case is very important and it's very sensitive to just go by the feelings and posts and a couple of pictures," Dr. Fia said.
"But she has this mark in her eyes... that I can see when she's talking to me. I looked at the eyes and said 'oh my god that's exactly the mark.'"
Dr. Fia appeared alongside Julia on Dr. Phil on Monday night, where they further detailed why the 21-year-old believes herself to be the missing British girl.
Speaking about her earliest memories, Julia appeared to describe the location in Portugal was Madeleine was last seen.
"It was the beach and water, like sea or ocean, and there were turtles and children," she began. "I remembered light-colored buildings, like white or very light colors, sunlight on these buildings."
Watch Julia's appearance on the show below:Julia also opened up about being sexually abused by a man called Peter Ney. "I believe that (Peter Ney) can be related to Martin Ney," she said.
"Martin Ney was suspected in [the] Madeleine McCann case and Martin Ney is an international child trafficker, serial killer."
Dr. Fia carried out three separate forensic tests to determine Julia's true identity and they are awaiting the results that'll give the 21-year-old the closure she is seeking.
Further fuelling her belief that Julia is not the biological daughter of her parents in Poland, Dr. Fia said: "Julia's mom refused to do the DNA test and she refused to answer any calls, texts, or communication. At this moment, I kinda know the truth. But until I get an answer, it's hard to say 100% - but it's also hard to deny it 100%."
The episode of Dr. Phil aired on Monday and is now available to watch on YouTube.
