CORSICANA, Tex. — For more than 20 years, the prosecutor who convicted Cameron Todd Willingham of murdering his three young daughters has insisted that the authorities made no deals to secure the testimony of the jailhouse informer who told jurors that Willingham confessed the crime to him. 

Since Willingham was executed in 2004, officials have continued to defend the account of the informer, Johnny E. Webb, even as a series of scientific experts have discredited the forensic evidence that Willingham might have deliberately set the house fire in which his toddlers were killed.

But now new evidence has revived questions about Willingham’s guilt: In taped interviews, Webb, who has previously both recanted and affirmed his testimony, gives his first detailed account of how he lied on the witness stand in return for efforts by the former prosecutor, John H. Jackson, to reduce Webb’s prison sentence for robbery and to arrange thousands of dollars in support from a wealthy Corsicana rancher. Newly uncovered letters and court files show that Jackson worked diligently to intercede for Webb after his testimony and to coordinate with the rancher, Charles S. Pearce Jr., to keep the mercurial informer in line.
