A 29-year-old East Islip man already accused of drunken driving in a fatal crash earlier this month has been indicted on additional charges that includes aggravated vehicular homicide.

Charles Koukalenios pleaded not guilty Friday to aggravated vehicular homicide, aggravated driving while intoxicated, vehicular manslaughter, driving while intoxicated—the initial charge—speeding and reckless driving. Bond was set at $300,000.

The indictment stems from a fatal crash in Central Islip on May 4 that killed 84-year-old Mary Rogalle in her hometown, police said.

Police said Koukalenios was driving his 2011 Chevrolet Camaro north on Carleton Avenue when he crossed over into an oncoming lane and struck a center median when he tried to return to the northbound lane. He then lost control of the car, police said, and struck Rogalle’s 2002 Buick Century. Authorities said Koukalenios registered a .13 blood alcohol level four hours after the crash.

Rogalle was pronounced dead at Southside Hospital in Bay Shore, police said.
