The main event in question happened between approximatly 17:30 and 22:30 on 3rd May 2007. Just five hours in May which still have to be investigated and explained in full. At the time there exist but only two opposed versions (vers. 1 and vers.2) of the event.
A summary can be found on → McCannFiles:
“It should be remembered that we know very little, as fact, about what happened throughout the day and evening of 3rd May. The inconsistencies in the statements made by the McCanns, the tapas group and eye witnesses has led the Policia Judiciaria to believe that resolving this confusion is at the 'heart of the case'.”
