The face of the "lunatic" driver who killed his girlfriend in a horrific Bucks crash has been revealed.

Thames Valley Police has published the mugshot of Christopher Mattin, 34, after he was jailed for 10-and-a-half years on Friday.

Mattin, of Dairy Grounds, Kings Sutton, Oxfordshire, had been driving at 91mph along a 30mph stretch of Stowe Avenue, near Buckingham, when he lost control and crashed into a tree.

Sarah Jacobs, Mattin's girlfriend and passenger, died almost immediately in the impact. Ben Gibson, Mattin's nephew and the backseat passenger, also suffered life-changing injuries.

Sentencing Mattin at Aylesbury Crown Court on Friday, Judge Francis Sheridan said: "You drove like a bat out of hell, like a complete lunatic and a selfish one, intoxicated and under the influence of drink and drugs.

“You killed this young lady’s mum and you maimed your relative.

“You were driving at massive speed, 91mph in a 60 and in a 30, three times the limit. You were clearly unfit to drive.

“Sarah Jacobs had her life snuffed out, snuffed out by your dangerous driving”

The court heard how Mattin was drunk, on drugs, disqualified from driving and had never even possessed a full driver's licence when he crashed on May 10, 2020, at around 6.30am.

He had been speeding at 91mph before losing control in a residential area and crashing into a tree.

After the impact, the car burst into flames. Mattin was able to escape the wreck, but Ms Jacobs, who was already dead, suffered severe burns before her body was recovered.

Mr Gibson, Mattin's nephew, fell from the car during the crash, and suffered severe injuries.

Mattin had initially pleaded not guilty to charges of causing death by dangerous driving and causing serious injury by dangerous driving, but changed his plea to guilty two weeks before the trial was due to start.

As well as a jail term, Mattin was also given a 10-year extended driving ban.
