I still stand by the first message I ever posted here, which is also the reason I signed up.
I believe Annie went to Amistad briefly and I believe she was supposed to be in Bennett's 10:30 AM class, which ended at 12 noon. It was a TA job and and a paid one to boot. She didn't show up, which is exactly why Bennett sent an email "around noon" that Annie didn't show up for work.
She is carrying notebooks which make sense. IF the news stories of the emails from Clark are true, she was likely carrying her mouse notebooks and the "rules" on protocol. This would explain the binder and slim book underneath.
She was killed between 10:10 AM (the time she entered) and 12:40 PM (the time Clark exited).
That is a very long time period. I don't even want to think about what could happen in that long period. And IF it is true that he entered Amistad AFTER she did, it suggests to me that his feeble mind thought that because he came in later and because they don't have to swipe to exit, that would make a "BIG" difference.
