Around twenty people mobilized in front of the Fontainebleau court. Ling-Diane Zhang, 25, has not been found since January 16.

The medical student is 1.55 m tall and was wearing beige jogging pants, a short black down jacket and white Nike shoes at the time of her disappearance. “We do everything we can to help them but despite our mobilization we are not professionals. Our area of action remains limited to searches in the forest carried out until nightfall and the distribution of missing persons notices in the city,” explains Caroline, who manages the Facebook group.
