The death toll from the collapse of an exhibition hall in Poland rose to 67 yesterday when a man died from his injuries, an official said.
"A 34-year-old man died in a hospital from injuries sustained during the accident," said Krzysztof Mejer, a spokesman for the government of the Silesia region.
Authorities gave up hope of finding any more survivors in the mangled wreckage of the hall after it collapsed during a racing pigeon event on Saturday afternoon.
Officials were turning their attention to demolishing the rest of the building.
Thirteen rescue dogs from Poland and the Czech Republic indicated that there were no more bodies in the debris, Mejer said on Sunday.
"The rescue operation is over," Mejer said. "We don't expect anyone else to be found under the wreckage."
CLEAN-UP STARTS
However, Janusz Gancarczyk, head of one of the firefighting units at the scene, said emergency workers would remove the wreckage carefully because "there is still a slight chance that some bodies could be under it."
About 500 people were in the building when its roof collapsed. The last person rescued alive was pulled out less than five hours later. About 160 people were injured.
Polish authorities said 51 of the victims had been identified by Sunday afternoon, including seven foreigners -- two Slovaks, two Czechs and one victim each from the Netherlands, Belgium and Germany. The Foreign Ministry in Berlin said two Germans were killed.
Rescue crews had used hand tools to carve through the sheet metal and snarled poles of the collapsed building so as not to risk harming any potential survivors.
Police initially said snow caused the roof to collapse. Transport Minister Jerzy Polacek told TVN24 television that there was about half a meter of icy snow on top of it at the time.
CAUSE UNKNOWN
However, the president of the Katowice company that organized the fair, Bruce Robinson, said that "the reasons are not clear" and that the firm was working with authorities to help determine them.
Grzegorz Slyszyk, a lawyer for the building's owners, said snow had been cleared regularly from the roof.
He said they had heard from a Belgian witness that the floor collapsed before the roof did -- raising the possibility of subsidence.
Other potential causes to be investigated include whether faulty building materials were used and how they reacted to the contrast between bitterly cold temperatures outside and the heated interior, Slyszyk added.
The "Pigeon 2006" exhibition at the 10,000m2 hall in the Bytkow district of the city had opened last Friday.
LOCKED EXITS
People who escaped have said two emergency exits were open, but other exits were locked, and that they saw people struggling to break windows to escape.
Crumpled bird cages were scattered inside the building near the entrance, and white and brown pigeons perched on the twisted rafters.
President Lech Kaczynski declared a national period of mourning that will continue until tomorrow. Visiting the scene of the accident, Kaczynski described it as "the greatest tragedy" to hit post-communist Poland.
