From the Daily Mail:

…Kortney Moore said she was in her writing class when a bullet went through the window hitting her teacher in the head. Soon after, the shooter was inside the room demanding to know the religion of her fellow students.

The 18-year-old laid on the ground next to some of the victims shot by the gunman but managed to make it out alive.  

Anastasia Boylan, 18, was one of Harper-Mercer’s victims who only survived by playing dead.

Her father Stacy spoke to CNN and described his daughter’s horrifying ordeal, saying that Harper-Mercer at one point asked who was Christian, and told them all to stand up.

‘And they would stand up and he said, “Good, because you’re a Christian, you’re going to see God in just about one second,”‘ said Stacy.
