This search turned up on the blog today, and given that Robert Murat is expected to be interviewed by police again, let’s re-cap on Robert Murat and the Tapas 9.
The shortest answer is no. At the time Madeleine disappeared there is no suggestion of a connection. ZERO.
After he was made an arguido, 3 members of the Tapas 9 remembered Robert Murat being at apartment 5A on the night Madeleine disappeared.
One problem is that neither Kate nor Gerry McCann remembers Robert Murat at the apartment that night. There was a shortage of translators between the English and Portuguese. Silvia Batista was working as well as she could on this point. Another translator, Mr Murat, would have been very valuable. But Kate and Gerry do not remember him that night.
Nor do the police.
After Robert was made an arguido, Silvia Batista, who knew the parents of Robert Murat but not Robert himself, thought Robert might have been at 5A on 3rd May, but she was not sure. She pointed out that an English couple working a bar in Luz were present that night and could clear things up.
That couple was Paul and June Wright, who helped in the first search and who knew Robert Murat. Both gave statements that Robert Murat was not there on 3rd May.
The police used a standard technique to try to resolve the situation. They got the 3 from the Tapas 9 into the same room as Robert Murat and had a face-off. The 3 stuck to their statement that Robert was present on the night. Robert stuck to his claim that he was not.
In brief, none of the Tapas 9 knew Robert Murat before Madeleine disappeared, but because of events, they became aware of him afterwards. I am not aware of any links beyond this.
