No report of any dead people yet.
I suggest that only the wounded that could make it out are amoung the counted. The dead are still lying there and not being counted as the media is still on the outside. Until the entire mall is cleared of all perps the time won't be taken to move the dead to the outside.
Of course, you're right. This may be far worse than it sounds, and it sounds bad enough.
They probably will lie there until all evidence can be obtained.
