A senior detective in the Madeleine McCann case has revealed new evidence and theories on prime suspect Christian Brueckner who is poised for release.
Brueckner will be freed on Wednesday after serving a seven-year sentence for the rape of a 72-year-old American woman in Praia da Luz two years before Madeleine vanished.
In 2020, German authorities declared Christian Brueckner their prime suspect for the abduction and murder of Madeleine, but charges have yet to be formalised.
Brueckner has also previously been convicted of unrelated counts of child sexual abuse and drug trafficking.
ITV's new documentary Madeleine McCann: Searching For The Prime Suspect, follows criminologist Dr Graham Hill, a former senior Met detective who was sent to Portugal in the early stages of the investigation, as he returns to Praia da Luz for the first time.
