Firefighters are working with the hypothesis that the sixteen-year-old adolescent disappeared in Roses (Alt Empordà) while riding a jet ski would have lost his vest at some point and sunk. Now, rescue efforts are focused on tracing the coast along the southern part of Roses, up to Begur and Palamós. Drones have also been flown over the Medes Islands and GRAE divers are making dives between two and four meters, taking advantage of the "acceptable" visibility in the area. Firefighters plan to trace the coast by helicopter this Saturday from Roses to Begur before suspending the search for the young man. This Friday's search will stop when night falls and will resume tomorrow morning.
