Nicholas Bain (1824 – December 15, 1854), also known as Nicholas Beheehan, was an Irish farmhand who worked for James and Francis Wickam on the Wickam 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. He was arrested on June 6 and hanged on December 15, 1854.
