From the Washington Post, Tuesday March 10, 2015:
CORSICANA, Tex. — More than a decade after Cameron Todd Willingham was executed for the arson murder of his three young daughters, new evidence has emerged that indicates that a key prosecution witness testified in return for a secret promise to have his own criminal sentence reduced.
In a previously undisclosed letter that the witness, Johnny E. Webb, wrote from prison in 1996, he urged the lead prosecutor in Willingham’s case to make good on what Webb described as an earlier promise to downgrade his conviction. Webb also hinted that he might make his complaint public.
Within days, the prosecutor, John H. Jackson, sought out the Navarro County judge who had handled Willingham’s case and came away with a court order that altered the record of Webb’s robbery conviction to make him immediately eligible for parole. Webb would later recant his testimony that Willingham confessed to setting his house on fire with the toddlers inside.
Jackson’s handling of the case is now under investigation by the State Bar of Texas, following a formal complaint of prosecutorial misconduct last summer. That grievance asked that Jackson be sanctioned or even prosecuted for falsifying official records, withholding evidence and obstructing justice.
On Monday, an attorney for Jackson said he expected the Texas bar to notify his client soon that it will pursue formal charges of misconduct. The attorney, Joseph E. Byrne, said Jackson would seek to have any such charges heard by a jury, as the bar rules allow.
