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.
The images we faced were unbearable. A scene worse than a nightmare. Screams ringing out in the icy cold, the smell of burning. It was apocalyptic, a young woman called Marie told the audience.
She had been in a bar opposite Le Constellation when the fire broke out and suddenly found herself helping the injured as they ran from the flames.
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.
In Crans-Montana, people have similar questions regarding the response to the tragedy. Currently, the only two formal suspects are the co-owners of Le Constellation, Jacques and Jessica Moretti. The duo has been remanded in custody following the fire.
Mobile phone footage reveals how a sparkler tied to a champagne bottle triggered the fire, quickly igniting the soundproofing foam in the bar.
As the crowd rushed for emergency exits, panic ensued, exacerbated by blocked emergency doors.
Witnesses and relatives echoed the need for justice, criticizing both the bar owners and local authorities for neglect and insufficient safety protocols.
