Father of Umpqua college shooting victim: Gunman singled out Christians-CNN
"The gunman, while reloading his handgun, asked the students to stand up and asked if they were Christians [shooting woundee Anastasia] Boylan told her family.
"And then he shot and killed them."
There are NO reports that Mercer was of a religion other than Christianity, the motive, at this confusing stage, seems to be that he had a dislike for all organized religion. But then why would he ask the victims if they were of one specific religion and not, "Are you religious?"
