MADELEINE McCann cops have still not searched the property of chief suspect Christian Brueckner’s lover.
That is even despite the rapist calling the woman on the night the three-year-old was taken.
The woman’s father and the German prosecutor urged police in 2022 to go to the compound in Portugal to look for potential evidence.
They were told about the site near Farol — less than 30 miles from Praia da Luz where Madeleine was abducted in May 2007 — but failed to act.
It belonged to the ex that Brueckner rang the night Madeleine disappeared, telling her he had been in Tomar — a renowned paedophile hub.
It was also where he regularly parked his camper vans.

His former girlfriend told his trial in Germany that during the call he said he was driving to her home — but she did not know if he arrived.
She said: “I don’t know if he came late that night and parked the vehicle outside and slept in there, and left that morning again.”
Her dad told The Sun on Sunday: “I’ve twice told the German FBI they must dig up the garden and home there.
“Unfortunately, I worry there could be a link.”
German prosecutor Hans Christian Wolters said: “We gave the information about the compound to the Portuguese police but I don’t know if they are going to do anything.
“We can only ask them. We can’t go on our own.”
German investigators believe Brueckner, 47, abducted and murdered Madeleine — although no charges have been filed.
He is on trial for rapes and indecent exposures unrelated to the Madeleine case.
He denies the charges.
