This might be the worst climbing accident I've ever heard of. It is one thing for someone leading to take a bad fall; they presumably chose to take the risks that caught up with them. But a 22 year-old girl, who has every reason to believe she is safe on a top-rope, being killed because of a failure of the anchor rigging? Awful, just awful, and all the more so because nothing like this should happen, ever.
May she rest in peace, and may her family find solace in her memory.
