The death of a young woman from Ayrhsire whose body was discovered by a roadside is now being treated as suspicious by police.

Officers found the body of Annalise Johnstone, 22, on Thursday afternoon in a wooded area by the side of the B8062 between Auchterarder and Dunning in Perthshire .

Police Scotland has released details of a silver Ford Galaxy, registration ST67 HXL, that may be linked to the discovery.

Officers also want to trace the woman's iPhone, wallet and medication.

Police had earlier asked anyone who used the road in the previous days and who saw anything suspicious to call them. They especially wanted to speak to drivers with on-board cameras who filmed their journeys.

Now Det Supt James Smith has confirmed Ms Johnstone's death was being treated as suspicious.

He said: "I would like to take this opportunity to offer my sincere condolences to the family and friends of Annalise at this time.

"We have specialist officers assisting the family through these difficult times.

"Our enquiries are continuing to establish the full circumstances surrounding this death and I would like to appeal to anyone who may have any information to come forward.

"Officers are carrying out forensic examinations as well as reviewing CCTV and speaking to the local community in and around the area."

Missing belongings He said Ms Johnstone left her home address in Ardrossan at about 17:00 on Wednesday 9 May and had travelled to the Tayside area.

She was last seen near Ruthven Court, Auchterarder, at about 22:00 that same day having been dropped off there.

Detectives want to trace the movements of a silver-coloured Ford Galaxy, registration ST67 HXL, which has been linked to the enquiry.

Det Supt Smith said: "I would appeal to the public who may have seen this vehicle to also contact police.

"We are also looking to trace her iPhone 5s mobile phone which is lime green in colour, within a red flip style case, and a small wallet which has the Marvel superheroes thereon.

"A clear bag of medication which is 4-5 inches in size which will have a sticker on it with Annalise's name is also missing.

"We are doing everything we can to try and find out what has happened to Annalise and would seek the assistance of the public in that respect.

"Please get in touch with us even if you think your information may not be relevant to the enquiry, it may prove vital in establishing what has happened to Annalise."

Ch Insp Ian Scott, local area commander for Perth and Kinross said: "We are aware the incident may raise concerns in Perthshire and the wider community but I would like to take the opportunity to reassure the public that there will be a visible police presence whilst investigations are carried out.

"I would like to thank the local community for their patience whilst this is ongoing and if anyone has any concerns or information, they should speak to an officer."
