In a heartbreaking escalation that has stunned Switzerland and the world, prosecutors in the Valais canton have dramatically expanded their criminal investigation into the catastrophic New Year’s Eve fire at Le Constellation bar in the upscale ski resort of Crans-Montana. What began as a festive celebration for hundreds of young revelers turned into one of the nation’s worst modern tragedies on January 1, 2026, claiming 41 lives—mostly teenagers—and injuring over 115 others, many with life-altering burns.

The latest development, revealed in early March 2026, adds a shocking layer: the mayor of Crans-Montana, Nicolas Féraud, along with four current and former local officials responsible for public safety and fire regulations, are now formally under investigation. They face the same grave charges as the bar’s French owners, Jacques and Jessica Moretti: negligent homicide, negligent bodily harm, and negligent arson. Documents show summons for questioning, including the mayor on April 13, amid suspicions that repeated safety lapses allowed the disaster to unfold.

Preliminary findings indicate the blaze ignited when sparklers attached to champagne bottles—raised triumphantly by partygoers—touched flammable acoustic foam on the basement ceiling, triggering a rapid flashover. Flames spread with terrifying speed in the overcrowded venue, trapping dozens in choking smoke and intense heat. Survivors described scenes of panic: screams echoing as people struggled toward exits, some blocked or inadequate. The bar, popular among teens (drinking age 16 in the area), had not undergone a full fire safety inspection in years, raising questions about municipal oversight.

The Morettis were the initial focus, detained briefly amid flight risk concerns, and accused of allowing unsafe practices like interior pyrotechnics near combustible materials. Yet the probe’s expansion to local authorities suggests systemic failures: ignored regulations, missed checks, and perhaps a culture of leniency in a glamorous resort town reliant on tourism. Families of victims, already devastated, now demand full accountability, with some confronting suspects in emotional court appearances.

This isn’t just a fire—it’s a betrayal of trust. Young lives full of promise were stolen in moments of joy turned to horror. As Switzerland mourns with national tributes and memorials, the investigation presses on, seeking truth for grieving parents who lost children to flames that should never have been allowed to rage. The pain lingers, the questions burn brighter: How many warnings were ignored? Who failed these innocents? Justice, though delayed, must come—for the 41 gone forever, and for a nation forever changed.
