A four-year-old girl has been found hiding inside a British-registered car in which three bodies were discovered eight hours earlier, French police say.
The three are thought to be British, a husband and wife, and a grandmother. An older girl from the family was found shot outside the car, in a critical condition.
A local cyclist was found shot dead nearby.
Mr Guillamet, who was camping at the same site as the family on the edge of Lake Annecy in the Haute-Savoie region, said the car was "riddled with bullets".
