Gardai in West Cork say they believe there are people with information about the murder of Sophie Toscan du Plantier who have not yet come forward.
Gardaí held a media briefing in Schull yesterday, almost 26 years after the French TV producer was killed close to her holiday home in Toormore.
Investigating officers say they have identified new witnesses in Ireland, France and the UK who will be interviewed in the future.
They are also appealing to anyone who was in contact with Sophie between 4:30pm on the 22nd of December 1996 and when her body was discovered on the morning of the 23rd to contact them.
Superintendent Joseph Moore said Sophie's family deserve to know what happened to her.
"She was a mother, a sister, a daughter, a wife, a friend. She has been denied the right of being a grandmother.
"She deserves the truth. Her family deserve the truth. And at this point I'm asking for any person without information to come forward and speak to us.
"The investigation team is based at Bantry Garda Station on the numbers. 027-20860 You can contact your local Garda station or the Garda confidential line on 1800-666-111.
