Katie Shields (18) died after her car has hit by a 4x4 driven by Charles Dobney (51) as she waited to make a right turn on the A16 at Hop Pole.

A Lincoln Crown Court jury heard Dobney's Grand Jeep Cherokee had been travelling at more than 70mph on the 50mph "arrow straight" road.

On Thursday the jury took less than two hours to convict him of causing Katie's death by dangerous driving on April 26 last year.

Recorder Sam Mainds adjourned sentence and granted Dobney bail on condition he surrenders his passport, telling him a prison sentence will "almost inevitably follow".

The judge also asked to be given details of a previous fatal accident in which Dobney was involved.

On that occasion he was at the wheel of a Mercedes estate which plunged into the River Glen at Pinchbeck late on a Friday night in August 1993.

Although Dobney escaped from the sinking car and made it to the bank, his wife Yvonne (32) died.

This week the jury heard how Miss Shields was returning from a shopping trip when she was hit by Dobney.

Mark Van der Zwart, prosecuting, said Dobney's Jeep hit Miss Shield's car as she attempted to turn off the main A16 onto a track leading to her family home.

Miss Shields, a sixth form student at The Deepings School, died instantly from her injuries.

Mr Van der Zwart said that in the minutes before the crash Dobney's driving attracted the attention of other motorists because of the speed he was travelling at in a 50 mph limit.

Tests later showed that he was driving at a speed of at least 70mph when the collision happened.

Motorist Mavis Taylor was overtaken by Dobney, of Park Lane, Surfleet, moments earlier after she pulled out from a side road onto the A16.

Dobney, who did not give evidence at the trial, later told police he had hardly any memory of what happened in the moments before the crash.

He will be sentenced on Friday, June 13.

Speaking after the hearing Katie's parents Kevin and Christine said: "We are very happy with the verdict and we just want to say thanks to Lincolnshire Police and the emergency services.

"We also want to thank all of our friends and family who have supported us through this traumatic week."
