British ex-pat Robert Murat says he will happily take part in a reconstruction of the night Madeleine McCann disappeared if asked to do so by Portuguese police.
Detectives want to recreate a "Crimewatch-style" event later this month in Praia da Luz, the Algarve resort where the toddler vanished just over a year ago.
Her parents Gerry and Kate McCann - who are still considered suspects, or 'aguidos' in the case - have not ruled out a return to Portugal.
But the two doctors say they are worried about how helpful it would be for the police investigation given the huge media interest in the story.
"It is under discussion. It is back to what additional information will help the search," Mr McCann added.
But Mr Murat, the third suspect in the case, confirmed through his lawyer Francisco Pagarete that he would help out if asked.
Mr Pagarete told Sky News Online: "If there was a reconstruction, he would take part - he likes having tea with his mother.
"That was the exact thing he was doing on the night of May 3, drinking tea, and then he went to bed."
But Mr Pagarete questioned the timing of the police reconstruction, adding: "In my point of view, it should have been immediately after the event."
Locals in Praia da Luz say they are surprised the McCanns have not yet agreed to help the investigation, even if it only has the slightest chance of helping police locate their daughter.
It is feared Mrs McCann, 40, would find such a trip too traumatic.
A friend of the couple said: "Kate is upset. There's been no sense of concern for her feelings or the anguish it will cause her.
"On an emotional level she is not sure she can go through with it."
The McCanns have not been back to the resort since returning to England in September.
