On a Saturday evening in January 2016 during a blizzard, 37-year-old Zdzislaw Golabek was found unresponsive with a single, fatal gunshot wound to the head inside an apartment on 45th Street in Sunset Park, Brooklyn. He lived in the same building; the shooting occurred in a neighbor’s unit and he was pronounced dead at the scene just before 8 p.m.

A 32-year-old resident of that apartment, Maciej Gorecki, was taken into custody. Early speculation suggested a game of Russian Roulette, but Gorecki told investigators he had been showing off a handgun and, believing it to be unloaded, pointed it at Golabek’s head and pulled the trigger as a joke. Gorecki was charged with manslaughter and second-degree criminal possession of a weapon.

What details about the evening or the relationship between the neighbors might help explain how this confrontation escalated?
