Madeleine McCann: Searching for the Prime Suspect.

In this powerful new documentary, criminologist Dr Graham Hill, a former senior Met detective who was in Portugal during the early stages of the investigation assisting local police, returns to Praia da Luz for the first time. Revisiting the scene of her disappearance, unpicking Brueckner’s criminal history in both Portugal and Germany and meeting those who knew him to build a detailed offender profile, Dr Hill examines the case against the man who remains the prime suspect- and who has consistently denied any involvement in Madeleine McCann’s disappearance.
