The Du Plantier Case: This gripping RTÉ One documentary airs tonight

In a heartbreaking new RTÉ One documentary which airs tonight at 9.35pm, the son of Sophie Toscan du Plantier reveals how her death impacted him and his family.

On December 23 1996, the body of Sophie Toscan du Plantier was found in a laneway outside her holiday home near Schull, West Cork.

Sophie's son, Pierre-Louis Toscan du Plantier, was just 14-years-old at the time and reveals how that day was his “last day of being a child,” adding, “She was everything for me.”

Sophie's murder was a tragic event that sent shock waves through the local community, and over 20 years later, her family are still searching for answers.

The Du Plantier Case documents the story of one of the most infamous murders in recent Irish history, looking at the case from both sides.

On one, a grieving family fighting for justice, and on the other, a man campaigning for his innocence.

In tonight's programme, viewers will hear unprecedented testimony form Sophie's mother, Marguerite Bouniol, and her brother Bertrand.

Although Ian Bailey was never convicted, he was publicly identified as a suspect in 1997 and has protested his innocence for the past 20 years.

Since then, he has brought his case to the High Court alleging a Garda conspiracy to frame him for murder.

Ian Bailey has now been indicted for murder by the French courts who want him to stand trial in Paris, however, this morning, the High Court refused to order his extradition to France, though it is still possible that he will be tried ‘in absentia’ in Paris.

As part of tonight's documentary, Ian Bailey was interviewed by reporter, Philip Boucher, along with his partner, Jules Thomas.

“It is in my mind and intention to write a letter to the DPP and I’m going to suggest that the DPP or the authorities in Ireland invite the French prosecutors to travel here to Ireland and to overview, under Irish law, my trial here. I would welcome it.”

The Du Plantier Case airs on RTÉ One tonight at 9.35pm.
