On the morning of April 10, 1936, Nancy Evans Titterton, novelist and wife of NBC Radio executive Lewis Titterton, was found sexually assaulted and strangled to death in the bathtub of her apartment in Beekman Place, a prominent New York City apartment building. Upon first inspection, the crime scene yielded few clues—a fingerprint in the bathroom, a length of rope used to bind her hands, and little else.  Within a week, detectives were no closer to solving the case than they were on day one, until a break finally came when the rope and a single horsehair was traced to a local upholstery shop, and ultimately to an apprentice upholsterer named John Fiorenza, who, along with his boss, Theodore Kruger, discovered Nancy’s body while delivering a piece of furniture.  Eventually, Fiorenza confessed to assaulting and murdering Nancy Titterton, but claimed temporary insanity. At the trial, the jury rejected Fiorenza’s defense and he was found guilty and he was executed in January 1938. Although the case of Nancy Evans Titterton may seem rather straightforward, it stands as an early example of science and law enforcement coming together to solve a case that had previously seemed destined to remain unsolved.  Thank you to the Incredible Dave White of Bring Me the Axe Podcast for research and Writing support!
