That's a good report.

I notice how they say in this report that his mother worked at the school -- which is apparently now wrong.

How is it possible that all the news agencies to have all reported that. A school district official, when asked if she worked there, said that she is not in their database. That wasn't the question.

Could she have volunteered there and still not be in the database. Or had she been in the database and the school district removed her when she left.

How did this kid single out this school that was 5 miles away.

Here is a recent post with a scoop from NBC that adds info:

Gunman had "altercation" with school staff day before masssacre
