As dusk fell Monday, families waited outside the hollow carcass of the building, trying to glean information from officials about their missing relatives.
Adding a candle to the hundreds flickering by the perimeter fence, Zofia Zieba, was trying to find out what had happened to her niece's son, Radomir Kawecki.
He had been with a group of friends at the pigeon show but had left them to go to the toilet when the roof fell in.
"His friends are in hospital. They're all injured, but he's not there," she said.
"His parents are waiting at home and still hope that he will be found in some hospital. But after all this time..." Her voice drifted away.
"He's their only son, a great boy," Ms Zieba added, before being overcome by tears.
Nearby, Bozena Fraczek was standing in silent contemplation after lighting a candle.
She said she felt obliged to come to pay her respects to the dead.
"You can't not think about this. It's a tragedy of such proportions it weighs down on everybody," Ms Fraczek said.
Calls for lasting memorial
There are now calls for a permanent memorial to be built at the scene of the disaster, by chaplain who first counselled the survivors.
Henryk Kuczob, a fire brigade chaplain, said he was met by scenes of panic and terror when he got to the exhibition hall Saturday, shortly after the hall’s roof caved in.
"When they pulled out victims who were bleeding, that was a terrible sight. One survivor was shouting, 'Where's my brother?' Another one was shouting, 'Where are my pigeons, where's my equipment'?" said Father Kuczob.
"There should be some sort of memorial to the many people who lost their lives and hallowed this place with their blood. There should be something to keep their memory alive," Father Kuczob added.
Seriously negligent
Officials accused the collapsed building's owners of flouting safety laws.
Justice Minister Zbigniew Ziobro slammed the owners of the hall saying they had been seriously negligent.
"Several emergency exits were blocked and out of use on Saturday. Windows and doors had to be forced from the inside by people trying to flee, or by rescuers," Mr Ziobro told a press conference.
He also held up a thick block of ice, which he said had been taken from the corrugated iron roof of the collapsed building.
"This was apparently an attempt to save money on snow removal. It would be naive to say that the state of the roof had no bearing on what happened," he said.
A spokesman for the company that owns and manages the hall has denied that accumulated snow on the roof of the hall caused the accident.
