According to Mr Amaral in his book, Rachael, Fiona and Russell all recalled seeing Murat in the immediate vicinity of apartment 5 shortly after the realisation that Madeleine disappeared but took two weeks to disclose this and then only after having mingled with him for much of that time.
Bear in mind that the Tanner surveillance episode must have been carried out just before the PJ got a search warrant and searched the Murat villa on May 13th when later that morning Robert Murat was taken in for interview and given arguido status.
For The Profilers, Murat Is The Guilty Party
As if the memory of the McCann's family friends suddenly came back to them all, - Rachael Mampilly, wife of Matthew Oldfield, Fiona Payne, wife of David Payne, and Russell O'Brien Jane Tanners partner, recall having seen Murat on the night of May 3rd, shortly after the announcement of the disappearance, in the immediate vicinity apartment 5A. They themselves were in direct contact with him during the previous days. However, it is only on May 16th that they deliver this information to us. As for the officers of the National Guard who were on the spot, they didn't see him that night, only the next morning, when he came to offer his services as interpreter.
On July 11th at 10am, a confrontation is organised between the witnesses - Rachael Mampilly, Fiona Payne and Russell O'Brien - and Robert Murat. Nothing new comes out of it. The former persist in stating that the suspect was definitely in the area on the night of the disappearance. Murat denies the whole thing and even accuses them of lying. Each side stands its ground. The only positive aspect of this meeting: the McCanns' friends undertake to return to Portugal for the purpose of the investigation. That will not happen.
