Pics all at south end of all (to the left when walking down main hallway/entry).
Some anomalies here. Bluedress person is kneeling, but facing opposite way from Mecca. As if they are in the prayer position. The exit which you can see someone deke out of earlier in livestream is right behind them.
Shooter has not even shot in this direction in last 3 pics.
Blue dress person, switches to blue pants the second time shooter enters building.
