According to Governor Greg Abbott, the shooter at an elementary school in the US state of Texas announced his plans on Facebook shortly before the crime. He initially wrote that he would shoot his grandmother, Abbott said at a press conference on Wednesday.

His second post was that he shot his grandmother. About a quarter of an hour before arriving at the school, the 18-year-old wrote that he was going to shoot at an unnamed elementary school, the governor said.

According to Abbott, the shooter had no criminal record. However, it is not certain whether the gunman had any entries as a young person. That still has to be determined. Mental illnesses are not known, according to Abbott.

The governor also announced that the gunman shot his grandmother in the face – she survived. At school, he then broke into a classroom that was connected to another.

Abbott expressed special thanks to the police and the emergency services on site. “The reality is, as horrific as what happened, it could have been worse.”
