New details have emerged in the investigation surrounding the tragic fire at the Le Constellation bar in Crans-Montana, Switzerland, which claimed the lives of 40 people on New Year’s Eve. Investigators have learned that a service door in the basement was locked from the inside, a revelation made by bar owner Jacques Moretti. This new information significantly impacts the ongoing inquiry into the cause of the Crans-Montana fire and potential culpability.
The incident occurred on December 31, 2025, at the popular ski resort bar, leaving a nation in mourning and prompting a thorough investigation by Swiss authorities. Moretti reportedly discovered several deceased individuals when he unlocked the door from the exterior, according to Swiss broadcaster RTS. The public prosecutor’s office is now actively examining the implications of this discovery.
Investigation Focuses on Locked Door and Potential Manslaughter Charges
The locked basement door is now a central point of the investigation. Several patrons reportedly attempted to use the door as an escape route when the fire broke out, but were tragically trapped, ultimately contributing to the high death toll. Moretti maintains he is unsure why the door was secured.
However, if prosecutors determine that Jacques and Jessica Moretti were responsible for the door being locked, the charges against them could be substantially increased. Currently, the couple faces accusations of involuntary manslaughter, negligent arson, and negligent bodily harm.
Possible Upgrade to Murder Charges
The possibility of a charge of murder with contingent intent is now being considered. This would require prosecutors to demonstrate that the owners were aware of the locked door and consciously accepted the associated risk. A conviction on this charge could result in a sentence of up to twenty years in prison for each individual.
Additionally, investigators are scrutinizing the acoustic dampening foam installed in the bar’s ceiling. Jacques Moretti stated he replaced older foam with a new product purchased from Hornbach, a DIY retail chain.
Swiss media reports suggest that bar staff were aware of the potential fire hazards associated with the new foam. A waiter allegedly warned guests about the flammability of the soundproofing material on New Year’s Eve 2019. The prosecutor’s office is currently verifying the veracity of this claim, which could further aggravate the charges against the Morettis.
Acoustic Foam and Building Safety Regulations
The use of flammable materials in public spaces is subject to strict regulations in Switzerland, and across Europe. Building codes typically require materials to meet specific fire resistance standards, particularly in areas where large numbers of people congregate. The Swiss Federal Office for Civil Protection oversees these regulations and investigates incidents involving building safety.
The type of acoustic foam used, and whether it complied with relevant safety standards, is a key aspect of the investigation. Experts are analyzing the material to determine its flammability and contribution to the rapid spread of the Crans-Montana bar fire.
In contrast to standard practice, the replacement of the acoustic foam without proper assessment or adherence to safety protocols raises serious questions about the bar’s operational procedures.
The investigation is also examining the bar’s fire safety systems, including the presence and functionality of fire alarms, sprinklers, and emergency exits.
As the investigation continues, authorities are expected to interview additional witnesses and analyze forensic evidence. The focus remains on determining the precise cause of the fire, identifying any negligence or wrongdoing, and ensuring that such a tragedy is never repeated. The outcome of this investigation will likely have significant implications for building safety regulations and fire prevention measures in Switzerland and beyond.
