Hughes, who knew Charles through a friend, denied any involvement in her death. However, he made statements while in police custody that implicated him, one of his trial attorneys recalled this week.

But Hughes has insisted he is innocent. "The fact is I didn't kill anyone," he told The Associated Press last month from death row.
