Trial by Fire
David Grann on Cameron Todd Willingham, who was convicted, on scant scientific evidence, of a deadly case of arson, but who may have been innocent.
Cameron Todd Willingham stood on the front porch, chest blackened with soot, screaming "My babies are burning up!" A neighbor later told police he intermittently cried then fell silent, as if he had "blocked the fire out of his mind." David Grann investigates whether Texas executed an innocent man.
