Two drivers who caused a crash which killed a young mum-to-be have been jailed.
Ryan Williams and Christopher Cottingham became involved in a spat on the B1192 near Boston.
Kimberley See (21), who was a passenger in Williams’ Citroen Saxo was killed and both drivers were seriously injured.
Ms See, from Whaplode, was returning home from a night at Billinghay Fair with her friend Vicky Smart and Williams.
But as he drove along the B1192 at New York, Williams became involved in a spat with Cottingham, trying to block him from overtaking.
Williams, who had earlier blocked another motorist from passing him, repeatedly touched his brakes and drove onto the wrong side of the road to block Cottingham.
Then, as Cottingham tried to undertake him, Williams returned to his side of the carriageway. The cars collided and Williams’ vehicle hit a tree.
Mark Van der Zwart, prosecuting, said: “Cottingham saw the way Williams was driving. He should have slowed down or created a gap so there wasn’t any danger.
“Instead of keeping his distance and not engaging in what appears to have been something of a duel he got too close. The cars collided. It was enough to cause both drivers to lose control and both left the road.
“Kimberley was trapped and died inside the car. She was 20 weeks pregnant. There was no reason for this to have occurred but for the driving by the people involved.”
On Monday, a jury at Lincoln Crown Court convicted Williams (23), of Sussex Avenue, Boston, of causing death by careless driving as a result of the crash on October 14, 2011.
Cottingham (21), of New York Road, Coningsby, admitted the same charge.
Williams was jailed for a year and Cottingham for 46 weeks. Both were banned from driving for three years.
Judge James Sampson told them: “No sentence can adequately reflect the loss of Kimberley’s life. The lives of her family have been turned upside down.
“The consequences were devastating. You were equally the cause of her death.”
Michael Cranmer-Brown, for Williams, said: “The deceased was a close friend. He had introduced her to his girlfriend and they had become friends.
“He is wracked with guilt. It is something he will have to live with for the rest of his life.”
He said Williams has lost his job as a mechanic as a result of what happened.
Joe Spicer, for Cottingham, said his client had shown remorse.
“The clear evidence from all of the prosecution witnesses was that he is normally a careful but cautious driver. There is no evidence of speeding during the course of what took place and there is no evidence of other careless driving.
“He accepts it was a misjudgment given that he could have sat back and let Williams go on.”
