New evidence has surfaced that leads police to believe the McCann account of the night Madeleine vanished may be seriously flawed. Police believe they have evidence proving the children of the families were present, something the McCanns deny.
Several witnesses have come forward stating that only the McCann's apartment was visited by any of the parents that evening. One of the McCanns friends, Russell O’Brien, was absent from the restaurant for 25 minutes just prior to the disappearance.
Police are now utterly convinced that Madeline was killed inside the apartment and the body hidden, however they are unsure exactly by whom.

Investigating Officer: Paulo Rebelo.
