A 21-year-old Polish woman claims to be the long-lost Madeleine McCann who disappeared in 2007. But the mystery deepens as her family reportedly refuses to take a DNA test that could reveal the truth.

The woman, Julia Faustyna, has similarities with Madeleine including facial moles and a distinct brown smudge on the right iris. Despite this, her mother won't hand over a genetic sample. Private detective Fia Johansson has been representing Faustyna and believes that if any of her direct family members agree to take a DNA test, the truth could be revealed.

She has reached out to the family but they continue to refuse to cooperate. Kate and Gerry McCann have previously agreed to take a DNA test, but Johansson says it’s “not necessary” to disrupt them.

Francisco Marco, a second private detective linked to the case, has cast doubt on Faustyna's claims. However, if Faustyna’s parents simply take a DNA test, it could rule out that she is the abducted girl.

The mystery surrounding Madeleine's disappearance has caused much pain for her parents, and false claims have been made over the years. The case continues to baffle the world.
