From Texas Standard:
Papers across Texas and across the nation led the news with information on the carnage in Oregon Thursday at Umpqua Community College. Ten people were reported dead, including the 26-year-old shooter.
Investigators are now looking into an online conversation before the shooting took place. Someone wrote: "Don't go to school tomorrow if you are in the northwest."
But it's yet to be determined if the web post was made by the shooter, or if it was just an eerie coincidence. Either way, it didn't seem to set off alarms, raise flags or lead to a call to the authorities. Instead, it garnered plenty of responses like this:
"I suggest you enter a classroom and tell people that you will take them as hostages. Make everyone get in one corner and then open fire."
