Police responding to a ShotSpotter activation early Tuesday morning in Huntington Station found spent bullet casings on the ground in the area, but could not find anyone who’d witnessed someone firing a gun.

Suffolk County police said they are investigating whether the incident, which occurred on 10th Avenue, is related to two shootings in the area over the weekend.

Police said Second Precinct officers responding to the scene Tuesday at 1:30 a.m. found five men who reported hearing shots — and who said they saw “flashes of light.”

Police said, however, none of the men said they saw anyone fire a weapon.

Police did not say how many shell casings were recovered. There were no reported injuries.

Detectives are investigating if there is a link between the incident and two area shootings that took place Saturday.

In the first, a man was shot in the foot at the Long Island Rail Road commuter parking lot about 8 p.m., police said.

In the second, police said, someone fired shots at two men standing in the driveway of a home on East Sixth Street about 10:15 p.m. Some bullets struck a home while others hit a vehicle in the driveway next door. An 8-year-old child sleeping in the back of that vehicle was not hit, police said.

Police identified the man shot in the first incident as Jose Jurado, 20, of Huntington Station, who was walking through the railroad parking lot when a man stepped out of a vehicle and shot him in the foot. Jurado then fled to a 7-Eleven on New York Avenue where someone called police.

Jurado was taken by ambulance to Nassau University Medical Center in East Meadow where he was listed in stable condition. The status of his recovery was not known Tuesday.

Police ask anyone with information about the incidents to call Second Squad detectives at 631-854-8252 or Crime Stoppers at 800-220-8477. All calls will be kept confidential.
