THE BBC have announced a four-part documentary which will delve into the mysterious death of a Swedish woman whose body was found on an Ayrshire beach.

Questions are still left unanswered in the death of Annie Borjesson, a 30-year-old Swede and Edinburgh student who was found dead on Prestwick beach on Saturday, December 4, 2005.

The 30-year-old had travelled to Prestwick airport the previous day and was due to fly home to her native Sweden.

However, Borjesson was discovered face down and fully clothed by a dog walker on the South Ayrshire coast.

And now the BBC have announced their four-part series “Body on the Beach, which is being made by Glasgow-based production company Rogan Scotland. It is rumoured that show will present new evidence in the case.

A show description reads: “How did Annie Börjesson die? BBC Three and BBC Scotland have co-commissioned Rogan Scotland to make a series to try to find the answer to this mystery.

“The series will look at the death of a young Swedish woman, Annie Börjesson, whose body was found on Prestwick beach in South West Scotland in 2005.

“Immediately labelled as suicide by authorities, numerous question marks now exist over that verdict.

“Investigating the mysterious circumstances leading up to and following her death, the series will open up this cold case, piecing together information in the public domain and turning up new evidence.”

Annie’s death was officially ruled as suicide according to police and investigators, however family and friends of Annie have repeatedly rejected that decision, and back in 2014 spoke to the Advertiser about their grief and search for the truth.

Annie’s mother Guje Borjesson spoke about the hell she lived in for more than eight years living in the aftermath of her daughter’s death. Guje broke cover after a 19 page dossier handed into Police Scotland by The Scottish Review calling for the re-opening of her daughter Annie’s case was rejected by cops in June 2014.

She told the Advertiser: “She was missing 16 hours before she was found dead.

“I’ve tried not to be too harsh on the Scottish police but it seems to me that they are the criminals if they are refusing to investigate a crime.”

It has been suggested that Annie was mistakenly killed by CIA agents targeting a journalist with the same name who was looking into US rendition flights carrying terrorists through Prestwick Airport but Guje said: “It sounds like a crime novel but the circumstances surrounding my daughter’s death are so strange I’m ready to believe even that.

“I know for sure that one person was threatened by police. Two or three months after my daughter’s death this particular person was very helpful.

“Suddenly he stopped writing to me after two policemen from Glasgow had come to see him and told him that if he continued to help me and a murder investigation was opened he would be the prime suspect.”

Both Scottish and Swedish authorities have always maintained that the most likely cause of death to be drowning.

However, the Swedish government has refused to fully disclose files related to Annie’s passing, saying they have been classified as ‘secret’ and doing so may harm ‘national interests’.

After initially agreeing to release the documents detailing conversations with Scottish authorities in relation to the suspected suicide, the Swedish foreign ministry heavily redacted the files sent on the grounds of them being classified.

Explaining why the documents had been changed, Daniel Andersson from the Swedish Government, said: “Information has been deemed classified as secret according to the provision of Chapter 15, section 1 of the Public Access to information and Secrecy Act and as been redacted to the attached file.

“The reason for this is that information concerns Sweden’s relations with a foreign state and a foreign authority and it can be assumed that a disclosure will damage Sweden’s international relations or, in other ways harm national interests.”

Speaking in 2014, Annie’s best friend Maria Jansson said: “It is not only a feeling that makes us all convinced that something terrible happened to our Annie, there are also so many strange and unexplained things, many of which we believe are strong evidence that shows that the case should be re-opened.”

Hopefully, the BBC’s four-part series will shed new light on the strange death of Annie Borjesson.
