BAD REICHENHALL, Germany — Rescue workers today pulled the bodies of two boys from the ruins of a skating rink in this southern Germany town, raising the death toll to 13. Crews were still searching for a missing woman and girl.

The boys' bodies were found several hours apart after rescue crews and dogs resumed their search of the debris following a lengthy break forced by fears that the wrecked structure could further collapse. Eight children were among those confirmed dead.

Authorities said the boys and the missing girl were between 12 and 16, but did not give their individual ages. A 40-year-old woman was also missing as hopes faded of finding survivors after a second night of snow and freezing temperatures.

The roof caved in after heavy snowfall Monday afternoon with about 50 people inside, including many children on Christmas break from school.

On Tuesday afternoon, rescue efforts were halted after one of the collapsed ceiling crossbeams shifted. Special cranes were brought in, and workers spent the night tearing away pieces of the facade and the remains of the roof.

Rescuers using dogs, shovels and their hands found a 5-year-old girl with only minor injuries late Monday, but had found no one alive and heard no calls for help since then.

Prosecutors opened an investigation for possible negligence, an automatic step after a fatal accident.

All the victims came from the area around Bad Reichenhall, an Alpine spa town of 15,000 inhabitants on the Austrian border. People in the town questioned why a public building could not withstand a heavy but predictable snowfall.

Experts suggested a structural flaw was a more likely cause than the heavy snow that fell Monday.

Local officials said there was an 8-inch layer of snow on the roof at the time of the collapse. Mayor Wolfgang Heitmeier said that was well within the building's safety margin.

Still, town officials had planned to close the rink after the end of the day because the snow was continuing.
