Texas authorities said Friday that the gunman who killed 19 children and two teachers inside an elementary school discussed his interest in buying a gun in private online conversations, but backed away from earlier descriptions that he made public threats less than an hour before the attack.
Gov. Greg Abbott said Wednesday, a day after the shooting, that “the only information that was known in advance was posted by the gunman on Facebook approximately 30 minutes before reaching the school.” Abbott's claim prompted questions about whether technology companies could have provided advance warning.
