The man who police believe is the prime suspect in Madeleine McCann's disappearance has now been linked to a secret compound, giving authorities a new lead 14 years after the toddler's disappearance.
Christian Brueckner -- who is a convicted pedophile -- reportedly had access to the compound, located in Portugal’s southern Algarve region where the three-year-old British toddler went missing in 2007.
According to a new report, the compound belonged to Brueckner’s ex-girlfriend, German native Nicole Fehlinger.
German authorities recently discovered the compound when they interviewed Fehlinger’s father, Dieter, for a second time.
"No one knows that my daughter not only had the private residence in Portugal at her disposal, but also a separate compound,” Dieter told The Mirror.
“No one has ever searched there or the property has never turned up in connection with Maddie.”
Fehlinger's dad also told the outlet, four “aggressive” dogs guard the compound that has now been overgrown with weeds.
“The area is completely overgrown, not visible. No one could get in or out, only my daughter and perhaps Brueckner with her," he explained.
Madeleine went missing from her family’s apartment in Praia da Luz while on vacation in May 2007.
The toddler disappeared while she slept as her parents -- Kate and Garry McCann -- were nearby having dinner with friends.
The incident happened right before her fourth birthday.
According to The Sun, police do not believe Brueckner's former girlfriend has anything to do with Madeleine's disappearance.
Authorities named him as their prime suspect in connection to Madeleine's case last year after phone recordings allegedly placed him at the resort the night she went missing.
Brueckner has always denied any involvement in her disappearance.
He is currently serving time in a German prison for an unrelated rape conviction.
Brueckner has not been charged in the Madeleine case.
