A beloved Nassau County police officer was killed early Saturday while off-duty when a suspected drunk driver blew a red light and slammed into her on a Long Island roadway, authorities said. Police Officer Patricia Espinosa, 42, was driving westbound in her Alfa Romeo on Route 347 in Saint James around 6:06 a.m. when the alleged impaired driver failed to stop at the red light and barreled his Chevrolet Silverado pickup truck into her, according to the Suffolk County Police Department.
