Nancy Evans Titterton, a novelist, was tragically murdered in April 1936. Initially found in her bathtub, the investigation faced challenges due to a lack of evidence. Breakthroughs emerged when detectives traced a rope and a single strand of horsehair to John Fiorenza, an upholsterer who discovered her body and later confessed to the crime. Despite claiming temporary insanity, his defense failed, leading to his execution in 1938. This case illustrates the early integration of forensic science in law enforcement and highlights societal perceptions of mental illness and crime.
