Her belief escalated to an attempt to call the hospital where both the McCanns worked.
A 20-minute call to the switchboard led to a report back from the NHS trust’s communications manager to Operation Grange, the British investigation into the disappearance.
The jury was told Ms Wandelt made further attempts to contact the authorities and then Mr McCann directly via email in June 2023.
In one email, she wrote: “I could be your daughter, it’s possible I’m her.”
She added people were “trying to cover up the story” and claimed there were similarities between her and Madeleine, including having scars in the same places.
But her attempts went unanswered, which Mr Duck KC said “did not deter” Ms Wandelt – who then made contact with Madeleine’s younger sister Amelie via social media.
Telling her she was her “only hope”, she sent doctored images to show they were “somehow related” and claimed to have memories of life before the abduction, the court heard.
These claims, the court heard, were repeated in 2024 when Ms Wandelt is alleged to have “consistently” messaged Mrs McCann’s mobile over the course of a day – calling her “mommy”, claiming to recall feeding Madeleine’s younger brother Sean, of playing ring a roses in the back garden of the family’s home in Rothley, Leicestershire, and of the night Madeleine was abducted.
In one message, she said: “I remember you came to my room before the abduction, rubbed my head and said ‘I love you and I will find you’.”
The trial of Ms Wandelt, of Jana Kochanowskiego in Lubin, Poland, and Ms Spragg, of Caerau Court Road, Cardiff, continues.
