Hughes moved to Houston in 1983 from his native Buffalo, N.Y., where a rape charge against him was dismissed when the victim failed to appear in court.
He testified at his capital murder trial that he pulled a knife on "a guy who came up to me from behind" and "stuck him twice" but denied it was the 3-year-old boy or Charles.
"I didn't stab anybody," he said. "Stabbing and stuck is two different things."
