9:36:15: The individual I have on the phone is continuing to hear what he believes to be gun shots.
Two separate 911 calls for sure -- one from female and the other from male.
And there may have been more, including the nurse who called 911 after shooter had killed the principal and the psychologist, and would not have used the words "believes" and "thinks" at that point.
Can you post the dispatch conversations so I/we can check it out???
