A judge has detained a young motorist who caused a fatal crash because she was texting at the wheel, saying the case should send a "terrible warning" to anyone using a mobile phone while driving.
Nikita Ainley, 20, was sent to a young offenders' institution for three and a half years after she admitted causing the death of Mary Rutherford, 68.
Judge Stephen Ashurst at York Crown Court told her: "No message is so urgent that it requires someone to lose their life."
Ainley was driving to work at Asda in Bilton, near Hull, in her Renault Clio when she ploughed into a Fiat Panda, the court heard. She was 18 at the time. Mrs Rutherford, from Withernsea, East Yorkshire, was in the back seat of the Fiat, returning from a supermarket trip with friends.
The judge said the result of the crash, in a country lane between Hull and Withernsea, was a "scene of devastation".
Ainley initially denied she had been texting on her BlackBerry at the time of the crash. She said she had pulled over in order to exchange messages with a friend about a night out. But a painstaking inquiry by Humberside Police established that the last of two messages she sent was transmitted only 48 seconds before a witness to the crash dialled 999.
Judge Ashurst told Ainley: "No message is so urgent that it requires someone to lose their life as a result of it. It was your thoughtless use of a BlackBerry phone that has brought about a completely unnecessary death."
Ainley, from Roos, East Yorkshire, who has no previous convictions and was described as being a "normal young woman", was banned from driving for five years and ordered to take an extended driving test if she wants to drive again. She stood in the dock wearing a purple jacket over a black top and looking straight ahead. She cried as she was led down the steps to the cells.
Outside court, one of Mrs Rutherford's daughters, Dawn Timmings, said she had a simple message for drivers following the death of her mother on May 30 last year. Fighting back tears, she said: "Just put the phone somewhere where you don't need to hear it or see it. It's not complicated."
Despite Ainley's barrister, Heidi Cotton, saying her client was sorry for what she had done, Ms Timmings said she did not see any remorse. She said she wanted the defendant to have "some insight into the pain that she's caused".
