Gerry suggested they all split up & search. He went off searching alone. Before 10pm. Then he got seen by the Smiths. It isn't complicated.
He had no control over where his mates would go or even if they would do as he said. You?re clinging to an absolutely absurd scenario out of sheer desperation and haven?t begun to come to terms with the sheer absurdity of it even now when I have spelt it out for you.
Once again, and read it properly this time:
So to suggest that the most logical course of action in order to dispose of a dead body in a tourist town is to relinquish ALL control of the situation by waiting until AFTER raising the alarm and drawing attention to yourselves BEFORE hiding the body, and then PARADING that body through the very heart of that tourist town is completely and utterly absurd. But some people seem to think this is what actually occurred that a) the McCanns were really really stupid and b) the McCanns were really really lucky to have gotten away with the dumbest cover up plan ever concocted.
