An uncle of Sophie Toscan du Plantier says he believes 'all outcomes are possible' of a Garda review into her case.
The French filmmaker was beaten to death with a brick and a rock outside her holiday home in Schull in west Cork, two days before Christmas in 1996.
Jean-Pierre Gazeau told Pat Kenny they are hopeful, but tempered, on the outcome of the review.
"My reaction is of course very positive.
"At the same time, because we had after 25 years so many deception, that we have to keep - in some sense - a kind of expectating behaviour."

"But of course if something in Ireland - new evidence is unveiled - of course for us it can be considered as very positive.
"But all that is in the hand of the Garda and in the hands of the DPP.
"We cannot have any influence of that - just we are observers - we don't [want] to have just some noise which could give us wrong hope.
"We are very, very pragmatic and very, very realistic; we are waiting for official outcome."
And he says they have exhausted their options in France.
"We should find definite solution, it's not possible to wait for, we should find definite solution in Ireland.
"In France there is no other possibility... all is in the hands of Irish police and the DPP - and that's all."
Asked what would happen if Ian Bailey was eliminated as a suspect, he says: "All is possible - all outcomes are possible, of course.
"That will leave again a new, very strong interrogation [about] what happened really on December 23rd 1996 in Schull".

"Twenty-five years looking for justice, taking me a lot of time to fight, to respect and to take some time for speaking with you, for speaking with the Irish police, to the French police, to do the trial.
"I have to pay a lot of lawyers - so it's a nightmare, it's still a nightmare.
"You can never find some peace with this sort of thing.
"Every day, every week for 25 years I have information, I have an exchange with journalists, with people in Ireland, with people in France.
"So every day it's a nightmare", he said.
