I also did not know of her, but I looked her up.

She seemed like a great woman. That's a shame. I also hope they catch the guy.

It sure seems from the circumstances that if it were just a coincidence, that would be a pretty incredible one. The only article I could find on the actual event (Washington Post.com didn't have anything but Sept 11 memorial coverage) didn't have much info. Does anyone have a good article with more details?
