(AP) — The gunman who opened fire in an Oregon college shot one classmate after saying he could save her life by begging, and others were killed after being told to crawl across the floor, according to relatives of students in the classroom. Pastor Randy Scroggins, whose 18-year-old daughter Lacey escaped without physical injuries, said she told him that the gunman called to a student, saying: "'Don't worry, you're the one who is going to survive.'" Harper-Mercer then told the student that inside the shooter's backpack was "all the information that you'll need, give it to the police," Scroggins said, citing the account by his daughter. Scroggins also said his daughter heard the gunman tell one victim he would spare that person's life if the student begged, then shot the begging victim anyway. The law enforcement official who disclosed the existence of the manifesto did not reveal its contents but described it as an effort to leave a message for law enforcement. Stephanie Salas, the mother of Rand McGowan, another student who survived, said she was told by her son that the shooter asked victims whether they were religious but did not specifically target Christians. Law enforcement officials have not given details about what happened in the classroom. [...] they released a timeline that shows police arrived at the scene six minutes after the first 911 call and exchanged gunfire with the shooter two minutes later.
