That’s what I was thinking as well... However, in the first article I read on MSN (which was right before I came here), it did say that the shooter had entered the building before firing his weapon. Obviously a lot of conflicting stories at this point with the police being very tight-lipped about all of it thus far.
I thought at New Life Church, the gunman was shooting from the parking lot, outside of the church - but I could be wrong.
