Tragedy brought people together in Crans-Montana and brought the country to a standstill.
On Friday, just down the road from the bar where 40 young people were killed by fire on New Year's Eve, church bells rang in their memory.
They tolled right across Switzerland, to mark a national day of mourning.
Then, moments after the last notes of a special memorial service had faded, came the news that one of the bar's owners had been detained.
Swiss prosecutors said Jacques Moretti, a French national, was a potential flight risk. He and his wife Jessica, who is also French, are suspected of manslaughter by negligence, bodily harm by negligence and arson by negligence.
Many of the victims' families had demanded action like this from the start: more than a week after the fire, the anger in this community has been increasing.
At the main ceremony in Martigny, down in the valley, relatives of the dead were joined by survivors. Some had come from hospital for the memorial. People held white roses in their laps and gripped each other's hands for support.
Marie, a survivor, painted a gut-wrenching picture of the disaster, describing it as apocalyptic and detailing her frantic attempts to assist the injured as they fled the inferno.
Listening in the front row were the presidents of France and Italy, whose citizens were among those killed and injured in the fire. Both countries have opened their own investigations.
Meanwhile, crumbling family ties and lingering questions about the causes of this tragedy weigh heavily on the community. Jacques Moretti has been remanded in custody as investigations continue to unfold.
The chilling details of the fire reveal a pattern of negligence that had long been flagged by locals. Alarming risks had been evident, yet many crucial safety measures were not in place, igniting outrage and despair as the search for accountability unfolds.
In Crans-Montana, fresh flowers adorn makeshift memorials as the community collectively grieves for a night that shattered lives and lessons unlearned.
