A possibly drunken driver killed two men when he hit another car yesterday on the Wantagh State Parkway in Levittown, State Police said.

Oscar E. Ramirez-Lopez, 29, an undocumented immigrant from Guatemala, was driving a Ford Windstar north on the parkway when he sideswiped a Kia Sephia.

Driver Ilario Scuteri, 49, and passenger Daniel J. Gambardella, 46, died when the car went out of control into a tree at around 4:50 a.m.

Ramirez-Lopez, who cops said had been drinking, was charged with first-degree vehicular manslaughter.
