Two young brothers were killed and another man was wounded in an early-morning shooting yesterday on Long Island, Suffolk County cops said.

Enston Ceron Jr., 21, and Ricardo Ceron, 19, were sitting in a 1998 Nissan Altima on Lincoln Avenue in Brentwood when they were attacked at about 2:50 a.m., the cops said.

Both were pronounced dead at the scene.

The third man, sitting in a nearby car, was wounded and treated for nonlife-threatening injuries at an area hospital. His name was withheld.

Investigators said they were trying to determine a motive for the shootings.
