The state of Florida is killing an innocent person, Diaz said from the gurney

"The state of Florida is killing an innocent person," Diaz said from the gurney.

"The state of Florida is committing a crime, because I am innocent.

The death penalty is not only a form of vengeance, but also a cowardly act by humans.

I'm sorry for what is happening to me and my family who have been put through this."
