Erwan Blais, 18, disappeared on the night of February 10 to 11 in Deux-Sèvres. The Niort prosecutor's office explained to BFMTV "to work on all the hypotheses" The police have since stepped up their searches and combed the area with the help of a dog, a helicopter and a drone.

A “moment of solidarity” on Sunday must take place “in a positive and friendly atmosphere to share a moment of solidarity. Because the search continues and we are not giving up”
