Police concluded that Annie Borjesson had taken her own life
The mother of a Swedish woman who was found dead on a beach in Ayrshire three years ago will attend a memorial service for her in Prestwick later.
The body of Annie Borjesson, 30, was discovered on 4 December 2005 on the shore close to Prestwick Airport.
Police concluded that she had taken her own life but her family believe she could have been murdered.
The service for Ms Borjesson is due to take place at South Parish Church in Prestwick.
Her case has been highlighted on the website "A Search for Justice".
It states that during the autumn of 2004 Ms Borjesson studied English in Cambridge, before returning home to Sweden.
She travelled to Edinburgh in February 2005 to work.
When her body was discovered, she had been due to travel back to Sweden.
Ms Borjesson's luggage contained her Swedish passport and two library books, which she were to be returned to a library in Sweden.
She also had an appointment with her hairdresser in Sweden the following day.
After Strathclyde Police concluded that Ms Borjesson had taken her own life, her mother Guje and others travelled to Scotland to make their own inquiries.
They maintain that the information supplied by the police did not match their own, which pointed to a possible criminal act.
Ms Borjesson's family and friends are convinced that she may have been murdered and want the investigation into her death re-opened.
