The search was suspended at 2:35 p.m. local time (8:35 a.m. ET) Wednesday — well beyond the theoretical survival time for someone in the water. Two Jet Skis and a coast guard vessel involved in the hunt returned to port.
Local police will instead patrol the coastline.
Lt. Col. Christophe Triollet said teams were looking for “clues which could have washed up along the beaches.”
He added: “Other than that, we also continue our investigation to try to understand … the circumstances of his disappearance ... and to reconstruct the timeline and the facts to better understand the situation."
