Authorities in Switzerland have detained Jacques Moretti, co-owner of the Le Constellation bar, following a tragic fire that claimed the lives of 40 people during New Year’s celebrations on January 1st. His wife, Jessica Moretti, remains free under judicial supervision as investigations unfold. Swiss prosecutors have suggested the detention was necessary to mitigate a "risk of flight," highlighting the serious nature of the charges they face, which include involuntary homicide and arson by negligence, according to Reuters and Channel News Asia.

As part of the national day of mourning observed on January 9, church bells rang throughout Switzerland, and memorial services were held, including a minute’s silence in remembrance of the victims. Swiss President Guy Parmelin addressed attendees in Martigny, stating, "Our country is appalled by this tragedy. It bows before the memory of those who are no longer with us," as formal ceremonies and gatherings took place across the nation, according to India Times and CBS News.

Investigators are focusing on how the fire ignited shortly after midnight, with initial reports suggesting that sparklers attached to Champagne bottles ignited soundproofing material when placed too close to the ceiling. Authorities revealed that no fire safety inspections had been conducted since 2019, raising significant concerns over compliance with safety regulations, as reported by ABC News, Le Monde, and South China Morning Post.

The tragic event has impacted many young lives, with reports indicating that a significant number of victims were teenagers and young adults, some as young as 14. Italian officials have joined the investigation effort, with Prime Minister Giorgia Meloni stating that the incident was a result of negligence and demanding that those responsible be held accountable. Meanwhile, families of the deceased are grappling with their loss while also seeking justice, as voiced by Meloni and reiterated by officials in both Italian and French jurisdictions involved in the case, according to Al Jazeera, South China Morning Post, and Channel News Asia.
