Swiss Bar Owner, 49, Finally Cuffed for ‘Brutal Attack on Wife’ — Couple Now Face Prison Over Inferno That Claimed 41 Young Lives
The owner of a Swiss ski-resort bar where a catastrophic New Year’s fire killed 41 people has been placed in pre-trial detention on suspicion of violently assaulting his wife, adding a new layer of legal jeopardy to an already high-profile criminal case.
Jacques Moretti, 49, a French national who co-owned Le Constellation in the upscale Alpine town of Crans-Montana, was arrested at the couple’s home in the canton of Valais on the night of 11–12 August 2026. Authorities say the alleged attack left his wife and business partner, Jessica Moretti, requiring hospital treatment. The domestic-violence case is being handled separately from the ongoing investigation into the deadly blaze, but both spouses remain under formal investigation for their roles in the fire.
The tragedy unfolded in the early hours of 1 January 2026. Crowds of mostly teenage and young adult revellers packed the basement venue when sparklers attached to bottles of alcohol ignited highly flammable foam insulation on the ceiling. The fire spread with terrifying speed. Forty-one people died — the majority of them teenagers — and more than 115 others suffered injuries, many severe burns. Switzerland declared a national day of mourning. Families from Switzerland, France and Italy were among those devastated.
Prosecutors quickly opened a criminal inquiry against the Morettis on suspicion of manslaughter by negligence, causing bodily harm by negligence, and arson by negligence. Investigators examined multiple safety failures: an emergency exit that was locked from the inside, foam panels that had been installed without proper fire resistance, a narrowed staircase that hindered escape, and the absence of recent official safety inspections. Jacques Moretti was first detained in January 2026 after prosecutors cited a concrete flight risk based on his statements and personal circumstances. Jessica was released under judicial supervision.
Eight months later, the domestic-violence allegation has returned Jacques to custody. Lawyers for the couple have stressed that the alleged private incident must not be confused with the Constellation investigation. Yet the dual proceedings raise the prospect that both owners could face significant prison time if convicted on the fire-related charges. Under Swiss law, negligent homicide in cases involving multiple deaths can carry lengthy sentences, and the domestic-violence case carries its own penalties.
The fire has already prompted wider scrutiny of safety standards in Swiss nightlife venues, particularly those catering to young tourists in mountain resorts. Questions continue about how flammable materials were permitted, why exits were secured, and whether local oversight was adequate. Victims’ families have pressed for full accountability, while the Morettis have previously expressed grief and said they were cooperating with authorities.
As of late August 2026, Jacques remains in pre-trial detention on the domestic-violence suspicion. The fire investigation continues, with further hearings expected later in the year. The couple, once known for running a popular party destination in one of Switzerland’s most glamorous ski resorts, now stand at the centre of two separate criminal processes that together threaten to define the rest of their lives. The human cost — 41 young lives lost and dozens more permanently scarred — remains the starkest fact of the entire story.
