All 116 people injured in a bar fire at a Swiss ski resort have now been identified, officials have said. Forty people were killed when a fire tore through a busy venue in Crans-Montana on New Year's Eve, with victims' ages ranging from 14 to 39 years. While the dead had all previously been identified, work had been ongoing to establish who the injured are, some of whom remain in critical condition. Swiss police confirmed on Monday that 83 people remained in hospital, with the injured including at least 12 nationalities. Most of the injured suffered severe burns, which in some cases meant they could not be identified. Investigators said 119 people had been injured, but that number has been revised down in the latest update. A criminal investigation has been launched into the French couple who managed the Le Constellation bar - a venue known to be popular with a younger crowd in the ski resort town, where the drinking age is 16. Sparklers on bottles being carried too close to the ceiling were the likely cause of the fire, a preliminary investigation has found. Details have begun to emerge about some of those who lost their lives in the tragedy, including Charlotte Niddam, believed to be 15. Her family expressed their deep sorrow on social media. The mother of Arthur Brodard, 16, confirmed he had died in the fire, while Italian media named junior golfer Emanuele Galeppini, 16, as another victim.
