“(A 69-page True Crime Short with photographs) H. H. Holmes was a central character in Erik Larson’s hugely successful The Devil in the White City, which is planned as a movie starring Leonardo DiCaprio. Holmes is commonly viewed as a real-life Hannibal Lecter, a devious and cunning serial killer without equal. Holmes used the persona of a successful doctor and entrepreneur to draw untold numbers of young women to his three-story Chicago hotel to experiment on before killing them. Not one to waste, he’d often deflesh the corpses to sell the skeletons to medical schools. He enjoyed trying out methods of murder and watching his victims die. Scientists from his era believed Holmes’ brain would unlock the secret of his perversity, but he denied them the chance to find out. Today, we can figure him out without access to his brain. We know more today about the neuroscience of sadistic psychopaths and we can better understand what his brain – if dissected – would reveal. For the first time, we can look to research findings about killers to decode Holmes’s vile behavior.
