The two other messages said: “I’m going to shoot my grandmother” and “I shot my grandmother.”

The shooter has been identified as 18-year-old Salvador Rolando Ramos.

After he shot his grandmother in the face, he drove to the school and crashed his grandfather’s car, and carried a rifle inside, Abbott said at a news conference.

Democratic Texas governor candidate Beto O’Rourke interrupted Abbott’s news conference, placing blame on him for the 21 lives lost in the deadly Uvalde School Shooting.

“This is on you until you choose to do something different,” O’Rourke said.

The Democratic Texas governor candidate was met with a harsh response from Abbott and other officials on stage, including the Uvalde mayor calling him a “son of a bitch” before O’Rourke was escorted out of the auditorium by police.

“I was just about to say, there will be plenty of time to discuss and analyze what happened yesterday and do everything that we can within our power to hopefully prevent it from happening again,” Lt. Gov. Dan Patrick said.

Abbott blamed the shooting on mental health and other factors such as access to semi-automatic weapons being too easy to access. Cruz said Wednesday that more guns are the answer, suggesting arming teachers in the classrooms.
