A former Baldwin High School basketball star who admitted crashing a car while under the influence of alcohol and drugs, seriously injuring an 18-year-old passenger, was sentenced Thursday to 3 years in prison.

Keira Corbin, 21, of Wyandanch, was sentenced in Nassau County Court by acting Supreme Court Justice Christopher Quinn.

Corbin, who led her high school team to victory in the 2011 Long Island Class AA Championship, pleaded guilty in June to second-degree assault, reckless driving and driving while impaired by drugs and alcohol. She agreed to the 3-year sentence as part of a plea deal.

Authorities said the 5:20 a.m. crash on March 1, 2014, happened when Corbin lost control of a borrowed Chevrolet Cruze while trying to exit the Meadowbrook State Parkway in North Merrick to get on the Southern State Parkway.

Acting District Attorney Madeline Singas said in a statement that Corbin had been using a cellphone and driving 111 mph, which made "this terrible crash and the serious injuries inevitable" when combined with alcohol and drug use.

On the day she pleaded guilty, Corbin admitted using marijuana, being drunk and having Xanax in her system at the time of the crash.

Prosecutors said the car rolled and a guardrail cut open its roof, with the ragged edges causing a serious scalp injury and severing part of an ear of the 18-year-old woman, one of two backseat passengers.

The other passenger had minor injuries, according to prosecutors, who said Corbin asked people who stopped to help to not call police.

Defense attorney Monte Malik Chandler of Hempstead said at the June hearing that his client attended Farmingdale State College, worked in retail and has apologized to the victims.

He said while the former star athlete "clearly made some serious mistakes," he believed "the damage that was done is not commensurate with the plea offer that she was given."
