Texas may well be about to admit that when it — scratch that; WE — executed Cameron Todd Willingham in 2004 for murder-by-arson after a 1991 house fire killed his three children, the state was actually murdering an innocent man.

In a withering critique, a nationally known fire scientist has told a state commission on forensics that Texas fire investigators had no basis to rule a deadly house fire was an arson — a finding that led to the murder conviction and execution of Cameron Todd Willingham.

The finding comes in the first state-sanctioned review of an execution in Texas, home to the country’s busiest death chamber. If the commission reaches the same conclusion, it could lead to the first-ever declaration by an official state body that an inmate was wrongly executed.

Indeed, the report concludes there was no evidence to determine that the December 1991 fire was even set, and it leaves open the possibility the blaze that killed three children was an accident and there was no crime at all — the same findings found in a Chicago Tribune investigation of the case published in December 2004.

Willingham, the father of those children, was executed in February 2004. He protested his innocence to the end.

Among Beyler’s key findings: that investigators failed to examine all of the electrical outlets and appliances in the Willinghams’ house in the small Texas town of Corsicana, did not consider other potential causes for the fire, came to conclusions that contradicted witnesses at the scene, and wrongly concluded Willingham’s injuries could not have been caused as he said they were.

The state fire marshal on the case, Beyler concluded in his report, had “limited understanding” of fire science. The fire marshal “seems to be wholly without any realistic understanding of fires and how fire injuries are created,” he wrote.

The marshal’s findings, he added, “are nothing more than a collection of personal beliefs that have nothing to do with science-based fire investigation.”

Over the past five years, the Willingham case has been reviewed by nine of the nation’s top fire scientists — first for the Tribune, then for the Innocence Project, and now for the commission. All concluded that the original investigators relied on outdated theories and folklore to justify the determination of arson.

Even better: the fact that the “experts” who called it arson were full of shit was apparently clear to anyone looking into the facts in plenty of time to save this man’s life. Governor Perry ignored those facts. Thanks, Goodhair! Way to go!
