Instead, he discussed matters already mentioned in letters to the journalist.
“The most important thing for me is of course the fact that I have been in prison for many years for something that I could not have committed and that half the world believes me to be a cruel rapist,” he allegedly wrote in one letter.
He has also claimed he was “ᴀssaulted by another inmate — at least one rib was broken.”
“I now stay in my cell 24 hours a day. I don’t go out. Not even for food.”
Brueckner was acquitted for five non-related Sєx offences. These included three separate counts of rape and two cases of exposing himself to children.
But German authorities are reportedly looking to build a case against Brueckner as cops scour more than 20 plots of land in Praia da Luz.
Madeleine McCann, then three years old, vanished from a holiday spot near his house on May 3 2007 – becoming perhaps the most high-profile missing persons case this century.
Portuguese police have agreed to cooperate with the search after judicial authorities approved it following a formal request from German police and prosecutors, according to reports.
A source told the Sun: “German cops know it is now or never so they need to push ahead with every credible tip they have.
“Following Brueckner’s trial last year someone contacted them with theories on where anyone who took Madeleine might have dumped her, or her clothes.
“They told cops about trenches that were dug in Praia at the time Madeleine disappeared — and the house where Brueckner had lived on the edge of the village.
“Of course, all these places have been searched over and over again — but now they have a new weapon in their ground-scanning radar.
“It means they don’t need to dig for the sake of it. But as soon as they spot anything of interest they are ready to excavate and check it.
“With time running out they are praying they get a breakthrough.”
