Overview
- A New Year's night fire at the Constellation nightclub in Crans‑Montana killed 41 people including six Italian teenagers who were found to have been lucid and to have little or no alcohol in their systems.
- Autopsies delivered to Rome in June 2026 show the six Italian victims died mainly from severe burns and lethal carbon‑monoxide inhalation and that they remained trapped because a safety exit was closed.
- Investigators recovered WhatsApp messages and audio from staff devices showing owners and employees discussed a blocked emergency door, warned that table sparklers could ignite the ceiling foam, and referenced ordering large quantities of sparklers.
- Jacques and Jessica Moretti are under investigation in Rome for multiple manslaughter, injuries and negligent arson while Swiss prosecutors in Sion continue a parallel probe of 14 people and are expected to send their files to Rome.
- Victims' lawyers are pressing prosecutors to upgrade charges to omicidio con dolo eventuale on the grounds that owners knew of the blocked exits, the use of highly flammable acoustic foam and repeated pyrotechnic shows.
