Police are looking for a Volvo XC90 after a 16-year-old Ringwood girl died after a collision on the A31.
Jade Clarke was killed while riding her red scooter along the westbound carriage of the A31 near the Ashley Heath roundabout at around 8pm on Sunday February 24.
Police believe a number of vehicles were involved in the crash and police are keen to find the Volvo which left the scene before the arrival of officers.
Traffic Inspector Matt Butler said: "We know from our investigation so far that a number of vehicles were involved in the incident and one of these vehicles - a Volvo XC90 - left the scene before police arrived.
"I need to trace this vehicle and urge anyone with information to contact me. I particularly appeal to the driver to get in touch.
"The front of the vehicle will be damaged. If anyone is aware of a Volvo XC90 which has sustained damage or has been repaired in the last few days, they should call police urgently.
"I also urge any witnesses to the collision, and anyone with information, to contact me."
Witnesses or anyone with information should contact Dorset Police on 101, quoting incident number 24:393.
