Police are renewing an appeal for witnesses following the death of a 26-year-old woman who was involved in a single vehicle crash at Ditchling Common, near Burgess Hill, on Tuesday 4 June.
The woman had been a rear-seat passenger in the vehicle, a blue Vauxhall Corsa. She died at the Royal Sussex County Hospital, Brighton, shortly after 9pm on Tuesday (11 June).
On 4 June emergency services were called to the B2112 Common Lane at Ditchling Common after a car left the road and collided with a tree before overturning in a ditch near the Oaks Poultry Farm.
Also in the car were a 29-year-old man and a 22-year-old woman, both of whom were seriously injured. They too were taken by ambulance to the RSCH. All three casualties were from the Haywards Heath area.
The coroner has been informed. Common Lane was closed to traffic until 6.30am.
Anyone who saw what happened or noticed the vehicle being driven shortly beforehand, who may have dash-cam footage or who has other relevant information, is asked to report details online, to email email@example.com or to phone 101, quoting Operation Alto.
