French President Emmanuel Macron has said a new trial could be arranged for Ian Bailey if he travelled to France.
While Taoiseach Micheál Martin has appealed to anyone with information about the murder of French woman Sophie Toscan du Plantier to come forward.
Mr Martin and Mr Macron were asked about the filmmakers’ death while at a press conference during the French President's visit to Ireland.
Ian Bailey was convicted in absentia of the killing by a Paris court in May 2019.
Mr Bailey has consistently protested his innocence.
When asked what more can be done to ensure justice for her family given Ireland will not extradite Mr Bailey, President Macron said French authorities are considering their next move.
Taoiseach Micheál Martin said her murder was a “terrible, horrible deed.”
He said: “The murder of an innocent woman who loved west Cork and for the entire community in west Cork.
“It is still a source of great pain and great grief that such an atrocity occurred within what is a lovely community.
“And to the family of Sophie Toscan du Plantier, we send our sincere and ongoing sympathies but also empathy.
“I watched the recent documentaries and one could not but be struck by the nobility and dignity of Sophie’s family in respect of the enormity and the trauma that they have been going through.
“It is still an open investigation in respect of our police force...as you know we do not interfere in the judicial arm or judicial processes.
“But we want justice to be done.
“It’s a terrible stain in terms of our country and in terms of what happened, a person of great substance, who loved her visits to west Cork and indeed her family do.
“And as a person who loves that part of the country myself, it is incomprehensible what happened on that particular evening and it does continue to grip the Irish public in terms of interest and empathy with her family.
“We would appeal to anyone out there even at this stage that has any information that can contribute to justice being achieved here and that they will do so.”
Speaking to reporters at Government Buildings, President Macron said his thoughts are with the French filmmaker’s family and friends.
He said: “It is such a tragedy and of course so much suffering remains, personal suffering.”
Mr Bailey has consistently protested his innocence and complained that deliberate attempts were made to frame him for the crime.
The High Court here ruled that Ian Bailey cannot be extradited to France to serve a 25-year prison sentence imposed on him by a French court.
Speaking at Government Buildings, President Macron said because Sophie Toscan du Plantier is a French victim, legal proceedings were put in place in France,.
He said Ian Bailey has refused to come to France but if he did travel, a new trial “could be organised.”
President Macron added that the French court is now considering what to do next.
He said: “In this context, the Paris court of appeal launched an arrest warrant which at the moment and so far the High Court in Dublin refused to implement.
“The French court is now considering what to do next and will leave a window for a period of time for the Irish and the French courts to discuss and decide what to do next."
