GARDAI expect to have the results of forensic tests in the du Plantier murder by the weekend. Ms Sophie Toscan du Plantier (39), a French woman, was murdered in west Cork.
The appeal on Tuesday by Chief Supt Noel Smith to anybody shielding her killer had not yielded further information, according to gardai yesterday.
They continue to question local people who knew or met Ms du Plantier a freelance producer for French television. Reports that gardai have taken samples of hair from people in the area have been denied. Gardai have also denied they interviewed a woman they believe to be a suspect.
It is hoped that the forensic tests results will tell gardai whether Ms du Plantier was alone in her house on the night of her murder, or whether she had a visitor who was drinking wine with her.
It is not clear whether DNA tests have been carried out on hair found in her hand and believed to be that of her killer.
Gardai may also learn if the droplets of blood found on the ground between her battered body and the back door of her house was hers or that of her attacker. Her body was discovered at the laneway entrance to her home at Dunmanus West in the Mizen peninsula on December 23rd.
