I am very keen to trace this vehicle and would appeal to anyone with information to give my team a call.
Did you see the car in the area of the murder at around midnight on Saturday into Sunday (30 December)?
If you believe you may have seen this car anywhere subsequently, I would also urge you to get in touch as soon as possible.
