You are correct. He was arrested and released on bond. His case was referred to the Grand Jury by the DA who thought that since the guy was only beating him with his fists then perhaps he shouldn't have shot him.I believe the first CHL shooting in Texas was the one that occurred on the Mockingbird bridge in Dallas.
The CHL holder testified that he was afraid the guy was going to beat him to death due to how big he was and the fit of rage he was under. His attorney was sharp enough to have the Medical Examiner testify as to the fact that they had performed numerous autopsies on individuals that had been beaten to death by other people who were only using their fists.
The Grand Jury didn't take too long to "no bill" him.
