A shooting early Sunday outside a popular nightclub in New Rochelle left one man dead. Police say they arrived at the Casa de Laya nightclub on Union Avenue to find Rigoberto Nunez lying on the ground bleeding heavily from a gunshot wound under his chin. Salvador Nunez, his brother, says he is shocked by Rigoberto's death. Investigators say they don?t have details about what led to the shooting. They say they are searching for the gunman. They hope the surveillance camera from outside the club may hold some answers.
