I found another prisoner with ties to Rockport and Port Aransas. He was 16 in 1978 when he murdered an elderly woman and was arrested. I found a comment on a Port Aransas site that claims he had been arrested with some of his friends (sounds like he hung around with him) not long before the murder for stealing a car. He was tried as an adult and sentenced to life. It doesn't say he was at the Ellis Unit but the trial was held in Huntsville. His younger sister would have been around the age of WCJD but she seems to be accounted for. Its possible he could have had a girlfriend that wanted to visit him.
