In 2005, Williams was one of the subjects of Sister Prejean's book, "The Death of Innocents: An Eyewitness Account of Wrongful Executions". She noted that the defense had been weak, failing to discuss his low IQ of 65, which is below the range establishing mental retardation (now referred to as intellectual disability). Such people may be suggestible and it may have contributed to his confessing to officers. The attorney also failed to discuss mitigating factors such as abuse in his childhood. His lawyer was later disbarred for incompetence.
