AUSTIN — The Innocence Project says it's discovered new documents that undermine the credibility of a key witness at the trial of a North Texas man whose execution for the arson deaths of his three children continues to be debated.
The New York-based nonprofit said Friday it had discovered a handwritten note that suggests prosecutors may have given leniency to a jailhouse informant who said Cameron Todd Willingham confessed to killing his three children in 1991.
The note included an Innocence Project court filing says suggests the witness, Johnny Webb, was charged with second-degree robbery instead of first-degree robbery.
The note is not signed or dated.
The Innocence Project wants Texas to give Willingham a posthumous pardon following his 2004 execution.
