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, 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.
Sitting in the front row were the presidents of France and Italy, whose citizens were among those killed and injured. Both countries have opened their own investigations.
Back in Rome, Italy's prime minister vowed to make sure all those responsible were identified.
This was no accident. It was the result of too many people who did not do their jobs, Giorgia Meloni said.
For now, the only two formal suspects are the co-owners of Le Constellation, Jacques and Jessica Moretti. They are being investigated for causing death and injury through negligence but have not been charged.
Now Jacques Moretti has been remanded in custody. In a statement, the public ministry said the move followed a new assessment of the flight risk.
At the memorial, survivors and family members united in their grief and questions, demanding accountability and closure.
Weeks after the disaster, the community stands with flowers and silent prayers, seeking justice for the lost and healing for the living.
