A disqualified driver who crashed whilst out with his girlfriend admitted he had let her die rather than face the authorities.
Andrew Bennett, 20, should have called an ambulance immediately after Kirsty Cash shot through the windscreen of his Subaru Impreza. 17-year-old Kirsty, who had not been wearing a seatbelt, sustained serious injuries and lost consciousness.
But instead, Bennett - who had lost control of the vehicle and collided with a line of trees on Long Lane, Worrall - arranged for Cash to be driven home in another car before the 999 call was made.
In the eyes of Cash's parents, the extra half-hour spent moving her undoubtedly cost their daughter's life.
Her father, Stanley Cash said "It just cuts you in half to think that all Bennett would have had to do was dial 999 and Kirsty would still be alive today."
The police estimate that Cash had an 85% chance of survival if she had been treated immediately.
Bennett and two accomplices hoped they could conceal the accident - and so prevent police from finding out he had been driving without a licence or young driver car insurance - by setting fire to the already burnt-out Subaru. But he gave himself up just a day later when South Yorkshire police made a public appeal for his whereabouts.
In court, Bennett pleaded guilty to manslaughter, driving without a valid licence or motor insurance, and conspiracy to pervert the course of justice. His accomplice Steven James Scott admitted tying a sweatshirt around one of the Subaru's wheels and setting fire to it.
Det Insp Tom Whitely, in charge of the investigation, said "It was originally dealt with as causing death by dangerous driving but as the full circumstances emerged, particularly the actions of Andrew Bennett, it became clear that this was unlawful killing.
"Following a road traffic accident where a young girl was unconscious an ambulance should have been summoned immediately - there is no question about that."
A spokesperson from Hoot Car Insurance services, the young driver car insurance experts, commented on the tragic case, saying, "It's sad that someone was so concerned about not having motor insurance that they let another individual die."
