Jayne Evans: "The Porsche 944 was an 18th birthday present"

Satvinder Nijjer,19, ploughed into Lavinia and Winifred Carrington, 78 and 76, during a lunch break from his Wolverhampton school in February last year.

He is believed to have been driving at more than 60mph in a 30mph zone.

Nijer, who was convicted last month of causing their deaths, was also banned from driving for five years.

Nijjer: "Of previously blameless character"

Judge John Warner heavily criticised Nijjer's father, Surinder, for giving his son the red convertible Porsche 944 as an 18th birthday present, saying that he shared the blame for the tragedy.

"If he had thought about this he would have known this was an accident waiting to happen," he said at Birmingham Crown Court.

In sentencing, Judge Warner described the case as "a bad example of dangerous driving".

"You overtook as grossly excessive speed at upwards of 60mph in a 30mph zone on a damp road when it was plainly unsafe and you lost control."

'Criminal behaviour'

He said it was also clear that Nijjer had repeatedly driven at speed along the same stretch of road on previous days.

Killed: Sisters Lavinia and Winifred Carrington

"The term showing off is an emotive term, but has been used.

"I am sure you were showing your friends just what the car could do and what you could do in it during a short journey at the end of school lunch hour.

"Not one death, which would have been bad enough, but two deaths occurred as a result of your criminal behaviour.

"Mercifully, it would appear they did not know what had happened to them," he said.

The judge said that he had taken into account Nijjer's previously blameless character and "immaturity and lack of judgement" in sentencing him.

Mechanical defect

He also acknowledged that the effect on Nijjer's family, particularly his mother, had been "appalling" and that it was obvious his education had suffered as a result of the accident.

During the case, it was revealed that Nijjer, from Wolverhampton, had only received the £14,000 second-hand Porsche days before the accident.

His father had paid the £5,000 insurance premium.

Police said that the teenager had marked out a racetrack near St Edmund's Roman Catholic School and used it to impress his friends.

He is believed to have been travelling at up to 70 mph when he hit the two sisters.

Nijjer, now a student at Birmingham University, claimed he was only travelling at 30mph and the crash was caused by a mechanical defect.
