Winfield D. Gillespie, 39, was shot outside a home on Woodoak Drive in Baldwin, New York, in the early hours of September 5, 2015. He was found with a single gunshot wound just before 1 a.m., taken to a local hospital, and pronounced dead hours later. Gillespie had traveled from Stroudsburg, Pennsylvania, to the house to discuss a business transaction with a former associate and was the father of three.

Authorities arrested the homeowner, 45-year-old Nathan Barnwell, after investigators say an argument preceded the shooting and Barnwell hid the firearm. Barnwell was charged with first-degree manslaughter and two counts of second-degree criminal possession of a weapon; his attorney later said Gillespie brought the gun and it discharged during a struggle. In October 2017 Barnwell pleaded guilty to first-degree manslaughter, and at sentencing in January 2018 he received nine years in prison and apologized to Gillespie’s family.

Does anyone have information about Gillespie’s final visit to Baldwin or the events that led to the argument?
