The 21-year-old woman who claims to be Madeleine McCann has taken a DNA test to determine whether she is in fact the missing girl.
Polish woman Julia Faustyna made claims on social media that she believes she is McCann, the UK toddler who disappeared on a family holiday in Portugal in 2007.
According to the Sun UK, private detective Dr Fia Johansson, who is working on the case, said there is also the possibility she could be another missing girl, Livia Schepp, who went missing along with her twin sister in Switzerland in 2011.
"I've spoken to her about this and she is open to the fact she could be any missing child out there - not just Madeleine. Julia just wants to know the truth about who she is," Dr Johansson told the Sun UK.
Dr Johansson added Faustyna claimed she could be McCann because one of the suspects in McCann's case, Christian Brueckner, looked like a man who abused her as a child.
"Julia has taken a DNA test and we are investigating if it's possible to check her DNA with that of missing Livia," Dr Johnasson told the Sun UK.
"We are investigating all possibilities at this stage."
