A 16-year-old girl who pleaded guilty to charges after a fatal crash in Richmond County last year has been sentenced in Port Hawkesbury Provincial Court.

She was sentenced to 12 months' probation and 100 hours' community service for her part in the fatal crash in Grand River, Cape Breton, that killed a 17-year-old boy.

The girl, who was 15 years old at the time of the crash and cannot be identified because of her age, was driving with five other people in the car. 

The passengers, ranging in age from 13 to 22 years old, were all taken to hospital after the crash.

Allan Lafford, 17, of Chapel Island was later airlifted to the Queen Elizabeth II Health Sciences Centre in Halifax.

He died of his injuries a few days later.

Elizabeth Benoit, Lafford's foster mother, was at his side went he died. 

"For what she did she should have had more responsibly," Benoit said.

The driver's grandmother said the driver and victim are related.

"She's only a kid and she made a mistake," she said. "She made one big mistake and she regrets it."

In April, the girl pleaded guilty to careless driving and operating a vehicle with too many passengers.

A third charge — operating a vehicle without a licensed driver in the passenger seat — was dropped.

In addition to the probation and community service sentence, the teen is banned from driving for a year.
