In both cases:
The Texas school shared plans to attack a school on Facebook about 15 minutes before the gunman fired, the state governor said Wednesday, the weapon of attack was an AR-15 assault rifle.
Governor Greg Abbott also told a news conference that the gunman shot his grandmother in the face before going to elementary school, where he shot and killed 19 children and two teachers.
“The first post was to the point, he said ‘I’m going to shoot my grandmother,'” Abbott said.
“The second post was ‘I shot my grandmother.’ The third post, probably less than 15 minutes before school, was ‘I’m going to shoot an elementary school.’
Facebook quickly released a statement following Abbott’s remarks, saying the posts were “a private text message that was discovered after a terrible tragedy.”
Andy Stone, a spokesman for Meter, the parent company of Facebook, said: “We are working closely with law enforcement to investigate this.
Abbott gave an initial account of Tuesday’s attack.
“The first thing that happened was that the gunman shot his grandmother in the face,” he said.
“He then contacted the police. The gunman fled and while he was fleeing, a (vehicle) accident happened just outside the primary school and he ran to school.
“Officers … hired a gunman at the time. The gunman then enters the back door and descends through two small hallways and then into a classroom on the left.”
