Swiss authorities have identified all 40 people who died in the New Year’s Eve bar fire at the mountain resort of Crans-Montana, police said on Sunday, confirming that teenagers made up more than half of the victims.

The final 16 bodies were identified following the early hours Jan. 1 blaze at the Constellation bar, Valais Police said. The fire ranks among the worst disasters in recent Swiss history and has triggered a nationwide outpouring of grief.

Of those killed, 26 were teenagers. The victims included two 14-year-olds, one from France and one from Switzerland. Police did not release names, but the mother of a 16-year-old Swiss boy, Arthur Brodard, confirmed he was among the dead.

“Now we can start our mourning, knowing he is in peace,” his mother, Laetitia Brodard-Sitre, wrote on Facebook.

In total, 21 of the victims were Swiss citizens, seven were French and six Italian. Others came from Romania, Turkey, Portugal and Belgium, along with one Swiss-French dual national and a 15-year-old girl holding French, Israeli and British nationality.

More than 100 people were injured in the fire, including many with severe burns. Swiss authorities said 35 patients have been transferred to specialised clinics in Belgium, France, Germany and Italy.

Hundreds of people joined a silent procession through Crans-Montana on Sunday, while mourners also gathered for a church service where Bishop Jean-Marie Lovey said condolences had poured in from around the world, including from Pope Leo XIV.

“Countless people join us – people whose hearts are broken,” Lovey told the congregation.

Switzerland will hold a national day of mourning on Friday, with church bells ringing across the country and a minute’s silence planned, President Guy Parmelin said.

Prosecutors said the fire likely began when “fountain candle” sparklers were held too close to the ceiling during New Year celebrations. Two people who ran the bar are under criminal investigation on suspicion of offences including homicide by negligence, negligent bodily harm and negligently causing a fire. They have not been taken into custody, police said.
