In December of 1991 a fire swept through a small home in Corsicana, Texas. Cameron Todd Willingham escaped with minor injuries, but his three small children, none older than a toddler, all perished in the blaze. Willingham was a known bastard who slapped his wife around more than once, and two weeks after the fire he was arrested and charged with the murder of his children. Thirteen years later he was executed for the crime. The years between those two events saw substantial changes in the forensic field, particularly in regard to fire investigation, but every effort to revisit the case by those who believed the evidence now showed Willingham to be innocent were ignored, refused, and stopped in their tracks. Documentaries about arguably innocent men and women are nothing new, and while they all have value beyond the images on the screen their arguments are usually based on recanted testimony, evidence of corruption, and other examples of intentional human fallibility. Few make their case for the subject’s innocence on the power of evidence alone. And fewer still come to such a potentially tragic conclusion as Incendiary: The Willingham Case.
