Speculation is rife there’s new information about the Chevaline massacre 12 years ago.
In September 2012, near Lake Annecy, a British family – husband, wife and their two little girls, aged 4 and 7 were shot. The girls survived - although one was seriously injured.
A passing cyclist was also shot dead.
The motive and killer remain a mystery.
A new French judge, now in charge of the cold case, has ordered a reconstruction of the event which will take place on a disused airbase near Paris.
The victims’ lawyers will also attend.
The gun used in the attack has not been recovered, but it is known that it was a World War 2 era Swiss made Luger.
Summer droughts have forced many Swiss cattle herders down from Alpine pastures earlier than usual, but the traditional désalpes will still take place across Romandy this autumn
