Chevaline

French investigators admit that time is running out in their efforts to explain the murders on September 5th 2012 of British-Iraqi family members Saad al-Hilli, 50, his wife Iqbal, 47, and her 74-year-old mother, who were shot dead in a layby near the French Alps village of Chevaline along with French cyclist Sylvain Mollier.

State prosecutor says the 48-year-old ex-cop has 'no direct link' to murders though he is still under investigation for arms trafficking.
