A police officer has been found guilty of causing the death of a 16-year-old schoolgirl by dangerous driving.
Pc John Dougal, 41, had accelerated to 94mph (151km/h) in a 30mph zone before he hit Hayley Adamson in Newcastle in May, the city's crown court heard.
A police driving expert told the court that the patrol officer's speed was unjustified, but Dougal had claimed he had been driving safely.
The car's siren and lights had not been activated at the time, the jury heard.
Following the conviction, Judge David Hodson said a prison sentence was inevitable.
