I've been watching the live feed for awhile now at work, and talked to a friend of mine who has connections there and it seems that the original gunman, who is now dead, was black male, 50's, wearing navy attire was an officer who's work status had recently changed, aka disgruntled worker shooting.
Reports are that he opened fire from a 4th floor mezzanine that looked over the atrium and shot at people in the cafeteria below.
A cop was shot in both legs, a woman in the head another woman in the shoulder and they're all in surgery and should survive. They're not releasing exactly how many are dead and most places are still in lockdown.
There is a possible other shooter (mixed reports from eye witnesses), but everyone is also in shock/hysteria. The police are still searching, but no more shots have been fired for a few hours. I'm really hoping that everyone is safe and my thoughts are with the families of those who lost loved ones.
And yeah it is sad how this kind of thing has become so commonplace that it is no longer a big deal. It is and it's a tragedy that the US has come to that.
