James Holmes: Timeline of CU e-mails in twelve hours after shooting shows confusion, fear
At 11:41 a.m., police chief Abraham asked all non-essential personnel to leave a certain part of the campus so police using specially trained dogs could make sure it was safe.
Faculty and staff continued to wonder about Holmes's state of mind.
Meanwhile, the dean of the graduate school, Barry Shur, sought details about Holmes's status as a student and when he'd begun the process of withdrawing from CU.
And staff continued to share rumors, including this tidbit about Holmes's mom.
