That big ol' blurb of lights to the right represents a bunch of emergency vehicles responding to a wreck on northbound 287 right before the 730 exit. It looked like a tan pickup had rolled and, although I'm not sure, it looked like there was a sheet over the driver's area.
Edit: The Messenger's Update is reporting that it involves the fatality of a Decatur High School female student.
Edit #2: Fox 4 has a
blurb about it.
