Dorset Police are renewing their appeal for information about the driver of a Volvo XC90 which failed to stop at the scene of an accident in which Jade Clark, 16, was killed.
Jade was struck by a Volvo XC90 as she rode her scooter along the A31 near Ashley Heath at 8.23pm on Sunday 24 February 2013.
Today Dorset Police extended the investigation into Gloucestershire.
Dorset Police can confirm that the case is a joint investigation between the Force's Major Crime Investigation Team and the Traffic Department.
A dedicated team of officers have begun visiting all registered keepers of Volvo XC90s and so far in excess of 300 vehicles have been eliminated in over six counties.
Speaking directly to the motorist, DI Marcus Hester, of MCIT, said: "If you own or use such a Volvo XC90 we will be coming to visit you.
"I'm directly appealing for the person who failed to stop to come forward and help me with the investigation into the tragic death of 16-year-old Jade Clark."
Police can now reveal they are searching for a light coloured Volvo XC90 registered between 2003 and 2007. This will include vehicles with 52 to 57 plates and also those with personalised registrations.
DI Hester added: "If you know anything about where this car is or who may have been driving it, please call us.
"I am appealing to the public to search their conscience – someone clearly knows where this Volvo is. Do you know a neighbour, friend or colleague who uses an XC90? Has it suddenly disappeared?
"Or have you noticed a change in someone who drives an XC90? Have they become stressed or been off work sick?
"I believe the vehicle would have suffered front-end damage during the collision.
"Do you work in a body repair shop and have you been approached to repair this vehicle? Or maybe you work in a vehicle spares or car breaker yard and have received an enquiry for parts to repair a damaged XC90? If so please come forward – that one phone call could be the breakthrough we need."
