A woman who claimed to have a grandmother inside a writing class in Snyder Hall, where a portion the massacre unfolded, described the scene in a tweet. “The shooter was lining people up and asking if they were Christian,” she wrote. “If they said yes, then they were shot in the head. If they said no, or didn’t answer, they were shot in the legs. My grandma just got to my house, and she was in the room. She wasn’t shot, but she is very upset.
