Well, come on then...or do I have to spend hours googling again?
P.S. I reckon you've got inside knowledge of who owns all those private apartments in block 5 to have identified the owner of the grey car.

Pagasus please point to the evidence that sister witnesses have changed statements, as I recall it is not only them but six witnesses in total cast doubt over Murat alibi.

The barrister has described Mr Murat's behaviour that evening as "odd", saying Mr Murat insisted on going to change his clothes because it had been a long day - when they were certain he had already changed earlier. -
Second witness about his constant clothes change.
Three friends of the McCanns. It is understood they have given statements to police insisting Mr Murat introduced himself to them on the night Madeleine vanished. It is claimed he said: "I am Robert.
