The gunman warned about the shooting in private messages on Facebook minutes beforehand, a spokesperson for Meta said Wednesday. The warning on Facebook was made in "private one-to-one text messages that were discovered after the terrible tragedy occurred."
The gunman sent three messages on Facebook about 30 minutes before the shooting saying: "I'm going to shoot my grandmother," "I shot my grandmother" and "I'm going to shoot an elementary school," Texas Gov. Greg Abbott said at a press conference.
Abbott said the suspect was reportedly a high school dropout. Officials have reportedly not identified a criminal history for the suspect, but Abbott said he may have had a juvenile record, but that is yet to be determined.

Father of victim says he holds school, police responsible for the massacre
Jacinto Cazares, the father of Jacklyn Jaylen Cazares, a 10-year-old killed in the Texas elementary school shooting, told ABC News he blames the school and police for the massacre, not the murder weapons.
"I want to say we hold the school responsible for not having locked doors and no protocol, no training. Also the Police for not having a better and faster tactical response time. There was at least 40 lawmen armed to the teeth, but didn't do a darn thing till it was far too late," Cazares told ABC News in a statement.
He added, "The situation could've been over quick if they had better tactical training and we as a community witnessed it first hand. I'm a gun owner and I do not blame the weapons used in this tragedy. I'm angry how easy it is to get one and young you can be to purchase one."
