Luger retrieved from Lake Annecy may link to 2012 murder of British family in French Alps

French officials say a Luger pistol recovered from the bottom of Lake Annecy bears similarities to the weapon used in the notorious 2012 killings in the village of Chevaline, where a British-Iraqi family and a French cyclist were murdered. The case has remained unsolved for over a decade, and the discovery opens a new investigative lead.
