(CNN) -- At least one person was killed and at least two others were injured in a shooting Wednesday at a Texas courthouse, a judge said. The shooting occurred outside a courthouse in Jefferson County, Texas, Judge Larry Gist said. Witnesses saw an elderly woman dead on the sidewalk in front of the courthouse, said Kevin Steele, a reporter for CNN affiliate KBMT-TV. There was a defendant on trial. It was break time, lunchtime, and he apparently shot three people, maybe four," Gist told CNN. A witness in the case against the suspect was one of those shot, said Gist, who had left the courthouse for lunch and heard shots fired from a block away. Police shot the suspect, and the courthouse was evacuated after the shooting, Gist said. The suspect was in police custody Wednesday afternoon, Steele told CNN.
