The man accused of driving drunk and killing two Roslyn teens in a wrong-way crash was arraigned on a 15-count indictment and pleaded not guilty to all charges.

Amandeep Singh was indicted on several charges, including aggravated vehicular homicide, vehicular manslaughter, driving while intoxicated, drug-impaired driving, leaving the scene of an incident and new assault charges.

According to the Nassau District Attorney's Office, the 34-year-old was driving 95 mph on May 3 with cocaine in his system and had a blood alcohol content of more than twice the legal limit when he crashed into an oncoming car.

Nassau District Attorney Anne Donnelly says Singh was drinking at a party and continued drinking once he left. She says Singh had an empty bottle of tequila in his car and thought he was in New Jersey when police found him four hours after the crash.

The crash killed 14-year-old Ethan Falkowitz and Drew Hassenbein.

"A reckless driver stole the lives of two extraordinary young men. And on behalf of the DA's office, I extend my condolences to the Hassenbein and Falkowitz families," Donnelly says.

The prosecution said they have a variety of statements Singh gave that night because it was all captured on police body cameras. Donnelly says Singh also told police not to tell his wife he was out with other women that night.

Singh's attorney says his family is mourning the loss.

"He's in a very difficult position – he has been from the onset of this...it's very sad. He and his family will be mourning all of the loss in this case," said attorney James Kousouros.

Kousouros also says the defendant's family and friends remain supportive of Singh, "who is otherwise a good man, married with child, a college graduate, owned a business."

The crash also injured two other teens who were in the car that was struck.

"The two other teenagers that were injured will remember it for the rest of their lives," Donnelly says.

Singh remains behind bars. He is due back in court on July 25.
