“As of this time, the only information that was known in advance was posted by the gunman on Facebook approximately 30 minutes before reaching the school,” he continued. “The first post was to the point of he said ‘I’m going to shoot my grandmother.’ The second post was ‘I shot my grandmother.’ The third post, maybe less than 15 minutes before arriving at the school, was ‘I’m going to shoot an elementary school.’”
Facebook spokesperson Andy Stone said shortly after those comments that the messages described by the governor were “private one-to-one text messages that were discovered after the terrible tragedy occurred.”
A spokesperson for Abbott’s office directed inquires to the Texas Department of Public Safety, which did not immediately respond to request to clarify the allegation.
