Ling-Diane Zhang, a 25-year-old medical student, left her home in Houilles (78) on January 16 to go to Fontainebleau. Since then, her family has had no news and has taken steps to try to find her.

On Tuesday, Wednesday and this Thursday, around fifty gendarmes, from all over Seine-et-Marne, began a vast search campaign. “We searched the caves, the holes, we combed the terrain,” confides a soldier.
