The above is Cameron Todd Willingham. In 1991, Willingham was convicted of starting the fire that killed his three children. Willingham was executed by the state of Texas in 2004. The prosecution used bizarre evidence to prove to the jury that Willingham was a sociopath, including stating that his tattoo of a skull and snake was fit the profile of a sociopath, and that his Led Zeppelin poster was an indicator of occult activities. Since then, there have been multiple investigations into the evidence presented against Willingham...including an investigation by Gerald Hurst, a chemist known for his work investigating various arson crimes. Hurst stated that there was nothing to suggest Willingham started the fire that killed his children, and the innocence project has Willingham featured on their website as an innocent man that was wrongfully put to death.
