As stated in the article written by the legal scholars at the Innocence Project:
> "There is no reliable evidence proving that Marcellus Williams committed the crime for which he is scheduled to be executed on Sept. 24. The State destroyed or corrupted the evidence that could conclusively prove his innocence and the available DNA and other forensic crime-scene evidence does not match him."
DNA evidence is based on proven science, and the DNA evidence that was not destroyed by the state is exculpatory.
