Gardai hunting Sophie Toscan du Plantier's killer are tracking down everyone she was in contact with during her visits to Ireland.
Detectives are building up a profile of anyone she knew or was seen with during her regular holidays to west Cork in the last few years of her life before she was battered to death on Christmas, 1996.
They are also trying to establish if Ian Bailey, who was arrested twice over the killing but never charged, actually knew and had met Sophie before she died.
