Gardaí have issued a fresh appeal for information in the case of Sophie Toscan du Plantier.
The French woman was murdered at her holiday home near Schull in December 1996 and Gardaí are convinced that someone out there knows what happened.
Journalist Ian Bailey was arrested but was never charged with her murder in Ireland; Mr Bailey denies any wrongdoing.
The Garda Serious Crime Review Team is examining the case and Superintendent Joe Moore of Bantry Garda Station said, “We will not stop until we bring it to a conclusion.”
Gardaí want to speak to anyone who met the French woman during her trip to Ireland and hope this will help lead them to the killer.
“I want to establish the movement of Sophie Toscan Du Plantier between 4.30pm and on 22nd December 1996 and on the following morning when her body was discovered at 10am,” Superintendent Moore told journalists.
“Some person has knowledge of this period of time and we want them to come forward to An Garda Síochána.”
