On this day, April 10, in 1936, Nancy Titterton, a novelist and wife of an NBC executive, was found raped and strangled in her home in New York City. A single horsehair helped reveal the killer.

Titterton, 33, was discovered lying face down in her bathtub with her pink pajamas tied around her neck. Her wrists had been tied with twine.

The killing prompted a high-powered investigation and the early use of forensic science.

Horsehair used to stuff furniture was matched to a love seat that had been delivered to the home the day of her murder.

After five hours of questioning, upholstery shop worker Johnny Fiorenza, 24, confessed to killing Titterton. He was found guilty and executed by electric chair at Sing Sing prison.
