French police have revealed new details of their investigation into the murder of three members of a family from Claygate in Surrey. Saad Al-Hilli, his wife and her mother were shot dead in the Alps a year ago.
Police say that recordings Mr Al-Hilli made of his telephone conversations could hold the key to the case as Ronke Phillips reports.
Mr al-Hilli's brother Zaid, who is from Chessington, Surrey, is due to answer police bail next month after he was arrested on suspicion of conspiracy to murder amid claims he doctored documents to ensure he inherited the family estate.
French prosecutors say the inheritance dispute remains a central line of inquiry, and they are looking into the brothers' father's property in Baghdad.
Zaid al-Hilli denied any knowledge of why his brother was killed when approached by Sky News.
When asked if he knew why his brother died, he told the broadcaster: "No, no idea, absolutely none."
Police investigating the deaths of four people, who were gunned down while on holiday in France, say they've gleaned vital clues from recordings of phone calls made by one of the victims.
Saad al-Hilli, from Claygate in Surrey, was killed along with his wife Ikbal, his mother in law Suhaila al-Allaf and a French cyclist, near Annecy in south east France just over a year ago.
One of his daughters Zainab was shot in the shoulder, but survived, and the other Zeena was discovered hiding under her mother's corpse.
French and British investigators held a joint press conference today, at which they revealed that Mr al-Hilli had recorded all of his telephone calls and the audio files were now being analysed.
Annecy prosecutor Eric Maillaud said: "The victim recorded all his telephone conversations. We therefore have some very precise details."
