When officers arrived at the scene, they found four men had been shot inside the deli.
One man, identified as 47-year-old Manuel Cruz-Hernandez, was pronounced dead at the scene. The owner of the deli, 61-year-old Bolivar Rodriguez, of Amityville, was rushed to the hospital, where he died Monday.
Two others, 30-year-old Juan Ramone Avilla Roque, of North Amityville, and 40-year-old Daniel E. Acosta, of Copiague, were transported to local hospitals with serious injuries.
There is no word on what led up to the shooting, but 62-year-old Dionicio Calderon-Oseguera has been charged with one count of second-degree murder and three counts of second-degree attempted murder -- though one charge will be upgraded in light of Rodriguez's death.
Anyone with additional information is asked to contact Crime Stoppers at 1-800-220-TIPS.
