Tragic - and probably avoidable.
From what I've heard so far it was a combination of an aging 1970s construction and heavy wet snow fall. They checked the snow load a few hours before but still deemed it safe until they would have had started clearing the snow away later...
The question is why they cancelled a training session that would have been held later but didn't evacuate. We'll probably know more soon.
