A 29-year-old East Islip man was arrested and charged with drunken driving after a crash Sunday afternoon that killed an 84-year-old driver in Central Islip, police said.

Charles Koukalenios, of 129 Washington St., was charged with driving while intoxicated after his arrest by detectives from the Suffolk County Police Vehicular Crimes Unit, police said early Monday in a news release. He was not arraigned Monday because he remains hospitalized, authorities said.

Police said Koukalenios was driving his 2011 Chevrolet Camaro north on Carleton Avenue at about 3:30 p.m. when he crossed into oncoming traffic south of Spur Drive North, crashing into the 2002 Buick Century driven by Rogalle.
