Detectives continuing to question a woman in connection with the murder of a business graduate have made a further appeal for witnesses to come forward.
Catherine Wells-Burr, 23, known to friends as 'Caf', was found inside her burning red Ford Focus car, which was abandoned in a field by the side of a road near Ilminster, Somerset.
The grim discovery was made by firefighters alerted to the blazing five-door vehicle by passing motorists shortly before 6.30am on Wednesday off the A358 in Ashill.
A 32-year-old woman was arrested on Thursday night on suspicion of murder and currently remains in police custody.
Police also questioned two men but have since eliminated them from the inquiry.
Avon and Somerset Police have appealed for witnesses describing the death as "tragic and brutal".
Detective Chief Inspector Simon Crisp said: "Investigations continue into Catherine's death and we are still working to piece together her life.
"I am particularly keen to appeal to the driver of a dark coloured people carrier that we were believe was travelling from Ilminster to Taunton, past the scene about 6.10am on Wednesday. We believe the car braked at the point of the car fire.
"I would also like to speak to anyone who saw a white transit or smaller van or was in a white transit or smaller van that was parked in the vicinity of the scene.
"My final appeal is to members of the public who saw anyone in the area wearing a high visibility jackets, these people may have information that is significant to this investigation."
