Nicholas Bain (1824 – December 15, 1854), also known as Beheehan or Behan, was a farmworker responsible for a notorious murder in Long Island in 1854.
Bain was an Irish farmhand who worked for James and Francis Wickham on the Wickham Farmhouse on Long Island, New York. Bain murdered the Wickams on June 2, 1854. Bain had become romantically involved with Ellen Holland, a female servant of the household, but a dispute arose between them which led to James Wickam dismissing Bain from his service on June 1, 1854. In the early hours of June 2, 1854 Bain murdered the Wickams with an axe. Bain was identified because he left his hat and distinctively large bloody footprints. He was arrested on June 6 and hanged on December 15, 1854.
