Following the jury's sentence, Holst said outside the courthouse that she "couldn't be happier" with the decision.
Lead prosecutor Ed Shettle said it wasn't Granger's behavior in court but his actions during the courthouse shooting, his lack of remorse and his potential to hurt others that led jurors to their decision.
"Bartholomew Granger got the death penalty because he deserved the death penalty," Shettle said.
James Makin, one of Granger's attorneys, said he had hoped the jury would have decided against a death sentence, but added: "I'm a realist." Makin said he doesn't believe in the death penalty but acknowledged, "If I had a gun in that parking lot that day (of the courthouse shooting), I probably would have done something with it."
Granger testified during the trial that he emptied the 10-bullet magazine of his illegally purchased semi-automatic carbine, saying he fired toward his daughter. Then, when he saw his daughter was still moving while lying in the street, he ran over her with his pickup truck. The daughter spent three months in a coma.
The trial was moved 75 miles to Galveston, so jurors didn't have to walk past the crime scene each day.
Granger's daughter, now 22, was among the witnesses who testified against him.
Prosecutors said Granger parked outside the courthouse for hours, then ambushed the women when they appeared at the courthouse in the late morning. Sebolt also was outside at the time, accompanying a relative to the courthouse. She was shot twice and died in the revolving door at the courthouse entrance.
Granger subsequently came under fire from police, abandoned his bullet-riddled truck about three blocks away, walked inside a construction business and took several people hostage. At some point he was wounded and eventually overpowered by his captives, and police moved in to take him into custody.
