On the morning of February 14, 1977, a workplace mass shooting at the Neptune Worldwide Moving Company in New Rochelle, New York, left multiple people dead. James Green, a 45-year-old Black mover from Mount Vernon, was among the first victims. Witnesses say Green turned to run after the initial shots and was shot in the back, dying on a stairway to the second floor.

The shooter, 33-year-old Frederick F. Cowan, a recently suspended co-worker and U.S. Army veteran, entered the warehouse just before 8 a.m. wearing military-style clothing and armed with a semi-automatic rifle and several handguns. Cowan, who harbored racist and anti-Semitic beliefs and collected Nazi memorabilia, fatally shot three other employees—Joseph Hicks, Frederick Holmes, and Pariyarathu Varghese—and killed New Rochelle police officer Allen McLeod during a day-long siege. Cowan was later found dead from a self-inflicted gunshot wound inside the building; a search of his home turned up a large weapons cache and Nazi propaganda.
