Yeah. I've since been corrected on this. I wasn't sure if the relation between the chamber and hallway. Two completely different locations. I saw one video of people milling around and heard the shot and watched the girl go down. Didn't see anything that looked like a shooter. I doubt what I saw was the only video though.
Thanks for the response. Seems the tweet of the shooter is still up.
