Officers found “numerous expended shell casings” in the area after a search. Police said the incident “does not appear to be the result of a random act” and it is possibly related to an earlier reported incident — though police declined to detail that prior incident, citing the investigation.

Police asked anyone with information about the incidents to call them at 631-727-4500, ext. 332.
