On the execution platform, Campbell refused to stand. Corrections officers had to forcefully strap him to a board. Campbell then repeatedly moved his head so that neither the cloak nor noose could be put on easily. It took prison officials 90 seconds to place a hood on his head, and to fix the noose before the trap was opened. The execution took place, and Campbell was pronounced dead about two minutes later. An autopsy confirmed that he had died of a fracture of the cervical spine, and that his death was quick.
