French authorities say a Luger pistol recovered from the bottom of Lake Annecy is being examined for possible links to the unsolved 2012 murders of a British-Iraqi family and a French cyclist in the nearby village of Chevaline. Officials say the gun shows similarities to the weapon thought to have been used in the killings, providing a new lead in a case that has remained unresolved for more than a decade.

Both outlets report that investigators are now assessing the firearm as potential evidence. The development is notable because the murders have previously baffled investigators despite extensive searches and inquiries. The latest work focuses on technical comparison of the recovered pistol with the suspect weapon characteristics tied to the 2012 shootings. Authorities have not reported a definitive match or announced whether the pistol is conclusively connected to the Chevaline case.
