BREAKING: Charles Grant stabbed in nightclub

The Saints' defensive end was stabbed in the neck and a pregnant woman shot to death at an Atlanta nightclub Saturday evening. Holy shit. Grant was not seriously injured, though, but the immediate reaction is: WTF?!?!?

It would irresponsible to jump out with the whole "athletes getting into trouble" again storyline....but here are my questions, in no particular order:

--Why was Charles Grant there?
--Who was the woman who was shot and killed? Was she connected to Grant? Why was she there if she was pregnant?
--Who did the stabbing and the shooting? Have they been arrested?
--Where is the nightclub located?
--What lead to the incident?

--Is there anything I'm missing here???

NFL Network's Adam Schefter gets the jump on the story. The Saints said they know about the incident.
