Which still leaves the question why did no one who knew him say he was there that night ?
How many of the OC staff or holidaymakers would have known who he was? He had lived in the UK for years, only returning to Luz in 2005 and had spent much of his time from Sept 2006 to May 2007 in the UK.
Sylvia Batista said she had known the Murat family for over 30 years but she didn't know of Robert's existence.
