Dark Mysteries #14 (1953)

A convict who has a job preparing executed criminals for burial at the prison hatches a plan to escape. He finds out that there are two bodies that will be shipped out. One to a cemetery and one to a crematorium. He hides in the coffin with the corpse that is supposed to be shipped to the cemetery with plans of escaping once the coffin reaches it's destination. Unfortunately for him, the name tags on the coffins get switched and the coffin he's hiding in gets sent to the crematorium instead!
