Here's a snippet about Barara Sibley from TIME.

Quote..

Barbara Sibley was being a good mom—but she did not know she would have to walk into hell to prove it. Her eight-year old had left something at home and so she drove over to the Sandy Hook School to deliver it. But something was odd about the compound when she got there at around 9:30. "It's an elementary school," she recalls to TIME. “There are usually kids outside or something. It was very quiet." She ran into another mom at the front entrance, where visitors had to be buzzed in. Thats when it became clear something was amiss: the window next to the door had been shattered. "There was glass everywhere," she says. "And that's when we heard gunfire."

But she's not a teacher. She is a mother of one of the students. As for the lock-down that would have started with the sound of the gunfire in my estimation. If the Babara arrived at 9:30 as she says then maybe she did call 911 or maybe the other mom they mentioned in the article made the call. Hard to say.

But that would mean the shooting lasted longer than five minutes wouldn't it. We're shortly before 9:30 until 9:40 ?? Because they say the police didn't arrive until 9:41 and I think the shooter was still active at that time. Sounds like the official report is wrong.
