Movements of black Mercedes being traced after A189 crash killed cop
PC Jess Turnbull, 19, had been responding to a crash on the A189 Spine Road near Cramlington, Northumberland late on Monday (June 8) when she was struck by the Merecedes.[1] The car was unconnected to the original incident. She was taken to hospital but died on Wednesday, surrounded by her loved ones, having served with Northumbria Police's response policing team in Northumberland for less than a year.
Detectives are piecing together the movements of the 09-plate black CLC seen in the Blyth and Cramlington area on the day PC Turnbull was killed. The car is believed to have been in the area between about 3pm and 11.30pm on Monday, and officers want to hear from anyone who saw it or captured it on dashcam or CCTV. 
Sergeant Dave Roberts, from Northumbria Police's Serious Collision Investigation Unit, said their thoughts "very much remain" with Jess's family, friends and colleagues as the inquiry continues. He urged anyone with even small pieces of information about the black Mercedes, or footage from the Spine Road and surrounding routes, to get in touch as it "could prove important" to the investigation. Officers remain particularly keen to speak to members of the public who stopped at the scene on Monday night to help, and have asked them to come forward if they have not yet spoken to police.
Information, images and footage can be submitted via a dedicated online portal set up for the investigation, or by calling 101 and quoting reference NP-20260608-1198. 
He was subsequently further arrested on suspicion of causing death by dangerous driving and has been bailed while the investigation continues.
PC Turnbull had been dealing with a collision involving two cars in which the occupants of one vehicle fled the scene before she was struck.
Her death is understood to be the first time a Northumbria Police officer has been killed on duty since 2006, when PC Joseph Carroll was fatally injured after a prisoner pulled the handbrake in a moving patrol car.
