She went to the meeting knowing the meeting was about tenure. Most likely, rumors had been spreading throughout the faculty, as they do in any company, corporation, or educational facility, etc., and she had heard she would not be given tenure. She did bring a gun with her and as soon as the announcements were made, she pulled her gun and started shooting. Naturally, a lot of information will be withheld until this goes to court, “if” this goes to court.
Once this has been proved, this will be considered premeditated murder with the “Intent” to do bodily harm to others.
From all the information obtained at this time, she did plan this....this biology professor came to the meeting with the "INTENT" to kill as many people as possible because she was not given tenure. This is truly a sad sad situation. God be with those families who have lost their loved ones.

Actually the meetings was not about tenure, at least not hers. She had been notified some time ago. This was to have been her final semester. Now it certainly is.

So,there's a bit more to the story than "professor goes berserk when denied tenure". It still could be about tenure, but it could be about other disputes between her and the department.
