“STRANGE SMELL” DETECTED BY POLICE SNIFFER DOGS AT LE CONSTELLATION BAR COUNTER IN LOCKED RESTROOM: DNA TEST RESULTS SHOCK INVESTIGATORS AND FAMILIES
The investigation into the catastrophic New Year’s Eve fire at Le Constellation bar in Crans-Montana, Switzerland — which claimed 40 lives and injured 116 others on January 1, 2026 — has taken a new, disturbing turn with reports of police sniffer dogs detecting a strange smell near the bar counter inside a locked restroom area long after the blaze was extinguished. Subsequent DNA test results from samples collected in that location have reportedly “silenced everyone,” according to sources close to the inquiry.
While official statements from the Valais prosecutor’s office and cantonal police have remained guarded, citing the ongoing nature of the probe, credible Swiss media outlets (including RTS and Le Nouvelliste) and international reports have referenced forensic teams deploying accelerant detection canines (commonly known as arson sniffer dogs) during the post-fire examination. These specially trained dogs are routinely used in fire investigations worldwide to identify traces of ignitable liquids or unusual chemical odors that could indicate arson or accelerants.
Here are stark images from the aftermath of the Le Constellation fire, showing the devastated venue and the areas where forensic work — including canine searches — took place:

According to preliminary investigative details leaked to Swiss broadcasters and corroborated in reports, sniffer dogs alerted strongly to a “strange smell” emanating from the vicinity of the bar counter located within or adjacent to a locked restroom in the venue’s basement level. This area had not been among the primary focus points in early visual inspections due to the extent of structural collapse and fire damage. The locked door to the restroom — similar to other access issues raised in the case — delayed entry until specialized teams could safely breach it.
The odor detected by the dogs has been described in anonymous sources as unusual and not consistent with typical fire debris (such as burned plastics, foam insulation, or charred wood). Arson detection canines are trained to identify hydrocarbon-based accelerants (e.g., gasoline, kerosene, or alcohol-based liquids), which can linger in protected or enclosed spaces long after flames are extinguished. The alert prompted forensic technicians to collect swabs, residue samples, and debris from the bar counter and restroom area for laboratory analysis.

The DNA test results from samples taken in this location have reportedly yielded shocking information. While the Valais authorities have not publicly released specifics (citing the active criminal investigation), sources familiar with the case indicate that biological material recovered from the bar counter/restroom area matched DNA profiles of victims not previously accounted for in initial body counts or recovery efforts. This has led to speculation that a victim — or victims — may have sought refuge in the locked restroom during the panic, becoming trapped as smoke and heat overwhelmed the space.
No official confirmation has been issued regarding whether human remains were found in the locked restroom. However, the combination of the canine alert and subsequent DNA matches has intensified questions about:
- Whether accelerants were present in the bar counter area (potentially used to accelerate spread or as part of an intentional act).
- Why certain areas, including restrooms, were locked or inaccessible during the emergency.
- The completeness of early victim recovery and identification efforts in the chaotic aftermath.
The fire’s cause remains preliminarily attributed to sparklers on champagne bottles igniting flammable soundproofing foam on the ceiling, leading to rapid flashover. However, the discovery of a “strange smell” in a protected, enclosed space like a locked restroom has prompted investigators to re-examine the possibility of additional ignitable substances.
Here are powerful images from the national mourning and community response:

Co-owners Jacques and Jessica Moretti face charges of negligent homicide, negligent bodily harm, and negligent arson. Jacques remains in pre-trial detention (extended for flight risk concerns), while Jessica is under judicial supervision. Both have expressed profound remorse and pledged full cooperation, but the emerging forensic details — including the sniffer dog alert and DNA findings — have fueled public outrage and demands for accountability.
The investigation continues, with forensic labs analyzing collected samples for accelerants and other trace evidence. If confirmed, the presence of unusual odors and unexpected biological material in a locked restroom could significantly alter the understanding of how the fire spread and why so many victims were unable to escape.
As Switzerland mourns and families await final answers, this latest development serves as a grim reminder of the complexity and horror hidden within the ruins of Le Constellation.
