So sad. It always hits close to home when another climber dies. For me, even more so when I was occupying the same crag at the time the accident took place. My condolences to her family and friends. Thoughts also go out to those who witnessed, responded, and participated in the rescue. I know how difficult it can be to be so closely involved in an incident such as this.
I wonder if a girth hitched dyneema sling was involved.
