So lets assume you're right and the McCanns are directly responsible for MM's disappearance when do you consider was the last reliable sighting of MM alive and well?
Afaik the McCanns and T7 did not have access to a vehicle before 10pm 3rd May? For those that believe PJ were less than thorough, given the high profile nature of the case, its almost certain that many with a ghoulish interest in the case would take it upon themselves to descend upon PDL and scour the entire resort wanting to claim 'I found Maddie'!
I've watched a couple of docs which highlighted the bins that were taken to landfill and may not have been searched thoroughly. Another doc highlighted a lot of deep wells and I doubt these have been searched properly. I can't see how a body could be disposed of in the ocean unless a boat was used?
The Smith sighting of a man resembling GM was circa 10pm? If this is correct GM was observed elsewhere by numerous others?
The last reliable sighting of Maddie alive, that I believe, would have been when she was at the creche.
I don't trust the McCanns or David Payne's supposed sighting.
The Smith's sighting was just after 10pm.
Matt Oldfield gave the time of Kate's check as 9,50, Fiona Payne gave 9.45.
Gerry gives a much later time, surprise surprise!
Kate wasn't searching the apartment for 15 mins, therefore, on the basis that the alarm was raised before 10pm there is sufficient time for Gerry to be the man the Smith's saw, whilst he was out 'searching'.... alone..... IMO
