Suffolk County Police detectives are searching for a man believed to have fired gunshots at a troubled Huntington Station location early Saturday.

A ShotSpotter device was activated at 2:16 a.m. at Melissa Restaurant, 1419 New York Ave., Suffolk County police said, where several patrons reported hearing gunshots. Shell casings have been recovered from the scene and Second squad detectives have determined that shots were fired, police said.

The restaurant, at the corner of Pulaski Road, and an adjacent parking lot have seen other violence during the past few years, including one homicide.

Most recently in March, Francisco Palma, 38, of Farmingdale, survived a gunshot wound to his left arm that he sustained while sitting in his vehicle in the parking lot behind the restaurant at 1 a.m., police said at the time. In June 2014, Luis Ramos-Rodriguez, 38, of Huntington Station, was found stabbed to death behind the restaurant on a Saturday night.

Hundreds of residents frustrated with the violence in their neighborhood marched to Huntington Town Hall after Ramos-Rodriguez’s death after a spate of other unsolved murders in the area. In an earlier incident in December 2012, someone threw a glass bottle at a woman in the restaurant, striking her in the face and causing injuries.

The suspect in Saturday’s incident is described as a male wearing a gray hooded sweatshirt pulled tightly around his face, police said.

A woman who answered the phone at the restaurant Saturday afternoon said no manager was available and she declined to answer questions.

Police said the investigation is ongoing. Detectives ask anyone with information to call the Second squad at 631-854-8252 or Suffolk Crime Stoppers at 800-220-8477. All calls will be kept confidential.
