Northumbria Police have released footage showing two joyriders racing each other in Whitley Bay - just moments before one of them crashed and killed a young jogger.
William Dorey was running on the A193 The Links in the town when he was struck by a Renault Megane that had lost control and mounted the pavement.
The impact sent the 18-year-old victim flying into the air and left him with catastrophic injuries that proved to be fatal.
In the moments before the crash on May 7 last year the driver of the Renault Megane, Joshua Cherukara, had been racing his friend Harry Cable's Vauxhall Corsa along the coast.
At around 10pm that evening CCTV captured the moment Cherukara lost control of his vehicle and collided with Willliam Dorey.
A court heard how Cable had only passed his driving test four days before the tragic collision while in the moments after the collision Cherukara told a friend "I think I've killed him".
Now officers at Northumbria Police have released the footage as the joyriders were jailed at Newcastle Crown Court for a total of more than 11 years.
Both men admitted death by dangerous driving.
Sergeant Lee Butler, of the Force's Motor Patrols Department, said:
This is a devastating case which shows what can happen when people take for granted the damage a vehicle can do.
Cable, 18, of Deneholm, Whitley Bay, was jailed for 4 years 6 months for death by dangerous driving.
Cherukara, 20, of Dachet Road, Whitley Bay, was jailed for 6 years 9 months for death by dangerous driving.
The family of William Dorey released the following statement:
Today simply marks the end of the legal process that began a year ago with the death of our dear son and brother Will, a truly awful event for our family.
