In 1893 Dr. Oliver Crook Haugh, of Dayton, Ohio, boasted that he was on the verge of discovering a way to improve mankind; much like Robert Louis Stevenson had touched on in his book The Strange Case of Dr. Jekyll and Mr. Hyde. Instead, his use of cocaine and morphine turned Dr. Haugh into a monster who became a danger to nearly everyone who ever loved him. From the period of 1891 to 1905 it was thought that he had committed at least sixteen murders; with victims in Indiana, Michigan, Ohio and Wisconsin. Did he actually commit all of the murders? Did some of his victims die due to poor doctoring instead of outright murder? Was he guilty of the charge that eventually led to his execution at the Ohio Penitentiary in 1907? You decide.
