The Kings Park woman charged with driving while intoxicated after a fatal Smithtown crash killed an Island Park man in March pleaded not guilty to a 12-count indictment on Wednesday, Suffolk County District Attorney Thomas Spota said.

Natalia Simons, 36, was driving her Nissan Rogue north on Route 25A when she crossed over into the southbound lane around 12:05 a.m. on March 13, colliding with 59-year-old Larry Garwood’s Toyota Camry, Spota said.

Garwood, who worked as a radiology supervisor at St. Catherine of Siena Medical Center, was taken to the same hospital, where he was pronounced dead, Spota said. Simons was taken to Stony Brook University Hospital via Smithtown Ambulance, police said.

Simons was charged with aggravated vehicular homicide, first-degree and second-degree vehicular manslaughter, second-degree assault, aggravated driving while intoxicated, driving while intoxicated, reckless driving, speeding and failure to maintain a lane, the DA said.

She was released on $50,000 bail, Spota said.
