A search is being carried out for a woman with Asperger syndrome, who has been missing for nearly two weeks.
Police said concerns are increasing for 46-year-old Tracey Topham who disappeared from her home in Barnstaple, north Devon, on 1 November.
Ms Topham, who sometimes uses the name of Stacey James, has not been in contact with any family or friends.
Her car, a green Ford Focus, was found abandoned in a car park in Braunton on Wednesday.
Asperger syndrome is linked to autism and people with the condition can have difficulty with communication and poor social skills.
Sgt Paul Jones from Devon and Cornwall Police said there was "extreme concern" for Ms Topham's welfare.
"Following the discovery of Tracey's car in Braunton we have been carrying out inquiries in the village.
"We would like the public to help us by searching their own gardens, outhouses, sheds and garages."
Ms Topham is described as 5ft 3in (1.6m) tall, of medium build with shoulder-length fair hair. She was last seen wearing dark clothing.
Anyone with information is asked to contact police.
