From MS Statement taken on 26/5/07
States that it is not possible for him to recognise the individual in person or by photograph.
— Adds that in May and August of 2006, he saw ROBERT MURAT in Praia da Luz bars. On one of these occasions, the first, he was inebriated and spoke to everyone. He did not wear glasses at that time. He also states that the individual who carried the child was not ROBERT. He would have recognised him immediately.
From MS Statement taken 20/9/07
McCann turned his head down which was similar to what the individual did on 3rd May 2007 when we met him. It may have been the way he was carrying the child either. I would be 60-80% sure that it was Gerard McCann that I met that night carrying a child. I am basing that on his mannerism in the way he carried the child off the plane.
