A July 4 block party on Hudson Avenue in Roosevelt, New York, ended in gunfire and the death of 27-year-old Tavon Greenhill of Hempstead. The celebration, attended by roughly 75 to 100 people and featuring children’s bounce houses, a DJ and street vendors, was disrupted at about 7:30 p.m. when a dispute between two groups — reportedly beginning two weeks earlier — escalated and multiple shots were fired. Greenhill was struck in the back of the head and pronounced dead at the scene.

A 31-year-old woman from Uniondale and a 21-year-old man from Hempstead were also wounded and taken to hospitals in stable condition. Investigators later arrested two men: 34-year-old Michael Wright of Roosevelt, charged with second-degree murder, two counts of second-degree attempted murder and criminal possession of a weapon, and 29-year-old Lawrence Sims of Hewlett, charged with second-degree attempted murder, criminal use of a firearm and criminal possession of a weapon. Wright was held without bail and pleaded not guilty; Sims was released on bail.

Does anyone who attended that block party or knew Tavon have information that could help clarify what happened that night?
