WILTSHIRE Police are renewing the appeal for witnesses following a crash in which three people died.
The incident took place shortly before 5.45am yesterday morning and involved a silver Volvo S80 travelling towards Westbury from the Melksham direction.
It left the carriageway and collided with a tree before catching on fire.
A spokesman said: "Tragically all three occupants of the vehicle died at the scene.
"Due to the extent of the injuries sustained, formal identification of the deceased will take a number of days.
"It is believed that the deceased had connections to the Warminster and Melksham areas.
"Specially trained officers were required to remove the vehicle due to the extent of the damage."
The A350 between the Semington roundabout and Stony Gutter was closed for 11 hours.
Wiltshire Police would like to hear from anyone who witnessed the collision or saw the vehicle before the collision occurred.
Anyone with information is asked to contact the Serious Collision Investigation Team at Wiltshire Police on 101 or Crimestoppers on 0800 555 111 where information can be left anonymously.
