Rescue teams expanded sonar sweeps, added divers and deployed a remotely operated vehicle after Luigi Cavallari, husband of Minister Eugenia Roccella, resurfaced from a dive at Lake Vico saying he felt unwell and then disappeared while the boat was not anchored.Authorities are focusing searches along the southern shore where currents and night drift may have carried him away; divers, underwater cameras and a Rome helicopter have so far found no trace and operations will continue into the next day.Medical experts say thermal shock, a sudden circulatory collapse after moving from hot conditions into cold water, remains the leading hypothesis; Prime Minister
Giorgia Meloni condemned hostile social media messages against
Eugenia Roccella and urged respect while prosecutors monitor the case.
