A farm worker who strangled a woman and dumped her body in an Aberdeenshire field is facing prison.
Joseph Harrison claims to have heard alien voices
Joseph Harrison has been in hospital since admitting killing prostitute Susan Third and leaving her body in Catterline.
Harrison, 29, of Brechin, was originally charged with murder but admitted culpable homicide on the grounds of diminished responsibility.
Doctors have now suggested Harrison should go to prison.
He is due back in court next month to learn his fate.
Harrison picked up the 21-year-old prostitute at Aberdeen Harbour in February last year.
She saw Harrison weeping in his car because he had argued with his mother, then let him pour out his life story to her before saying she needed money.
CCTV security camera footage showed Harrison drawing money from a city centre cash machine before returning to his car.
However her partly clothed body was later found nearly about 20 miles away in a field near the village of Catterline.
Reports by pathologists suggested Miss Third had been strangled by a ligature such as a thin cord.
The court also heard that there was a 70% chance Harrison had sexual contact with the victim after she died.
Harrison talked about hearing alien voices and believed he was just an observer on earth. He was also said to be a heavy user of amphetamine and ecstasy.
He has been in hospital for doctors to carry out tests on his mental state.
Lord Abernethy was told at the High Court in Edinburgh on Tuesday that the latest medical report suggested Harrison should go to prison rather than Carstairs State Hospital.
