Unfortunately in Texas if you are already in prison for murder and kill again while in prison it is a capital crime. The law was passed because of a single man in the 80s named Brown. He had been sentenced to death but back then they housed death sentence inmates in general population until their execution date was set. The man murdered 8 of his cellies so he caught a new charge that took time to work it's way through the system and the state didn't want to execute someone with outstanding charges. He extended his own life by 15 years by killing new people.

That guys videos are funny when he covers a shooting. He covers the gun fore sound with a duck quack sound. It's pretty funny.
