The area was searched by nine vessels and a helicopter, while the barge was towed to shallower waters for a thorough and safe hull investigation by Swedish divers.
The chances of surviving unprotected in the Baltic Sea temperatures are slim, but there remained hope that the couple had survived in an air pocket inside the barge's hull. Meanwhile, Swedish authorities announced that one person was found dead on the ship's hull, while the other was still missing.
Swedish prosecutors said investigations were underway to determine alleged offenses such as gross negligence in maritime traffic, causing death by negligence and marine intoxication. The Danish Meteorological Institute stated that the fog was not dense and that the conditions were not unusual for the time of year.
