Eric Maillaud says that two years after shooting of British family in French Alps it will take a 'stroke of luck' to solve the case.

Move comes amid claims murdered British woman Iqbal Al-Hilli's 'secret' first husband may have been poisoned on same day as Alps shooting.

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

French authorities probing murder of British family and French cyclist say the 48-year-old local man had 'not appeared on their radar' until now.
