Clive Yorkin had a long criminal record behind him, including robbery, arson, and murder. Locked in solitary confinement, he clearly wasn’t getting out of prison anytime soon, so he agreed to undergo the experimental “Nephron Process.” The process would try to cure him of his violent impulses by making him associate crime with pain. Unfortunately Yorkin’s pleasure and pain centres were reversed, so the process drove him irretrievably mad. He escaped, and was next found standing over the dead body of Iris Allen. Police believed Yorkin to be her murderer until security camera footage showed he had only witnessed her death at the invisible hands of Professor Zoom. |
