The posted link only takes us to the front page (which when I first clicked it was about the death of a girl @ a fraternity formal and the one year anniversary of the death of a Kappa...no mention of a DZ). After further search, I found the accounts of the death of DZ Sister Nichole Birky. Such a tragedy. My thoughts & prayers are with the sisters of our Epsilon chapter.
Here is a direct link to the story about a candlelight vigil held in her honor:
