Stuart Jack murdered Laura Milne in a flat on Union Street
A man has admitted murdering a teenager and hiding her partly-dismembered body in a cupboard in Aberdeen.
Stuart Jack, 22, admitted murdering Laura Milne, 19, at a flat in Union Street in December last year.
He also attempted to defeat the ends of justice by trying to cut off her head, legs and breast, cutting off her ear and hiding her body.
Co-accused Debbie Buchan, 19, and Leigh Mackinnon, 18, both admitted attempted murder, at the High Court in Edinburgh.
The court heard Jack admitted kicking open a bathroom door at a flat on Union Street between 12 and 19 December.
He forced Ms Milne from the bathroom, removed items of her clothing and glasses, repeatedly punched and kicked her, forced her to the floor, stamped on her head and body, and repeatedly struck her on the head and body with a knife or something similar, murdering her.
He also admitted trying to conceal the crime and destroying evidence by cutting off her ear and attempting to cut off her head, legs and breast, then wrapping and binding the body with a plastic bin bag, curtain, bedding, sticky tape and dressing gown cords and trying to hide it in the loft space of the flat before hiding it in a cupboard.
Buchan and Mackinnon also admitted trying to hide the victim.
The case was adjourned until Wednesday when the facts of the case will be heard.
Grampian Police Det Chf Insp Mark Cooper said: "This is a tragic case involving a vulnerable young lady who had clearly sought friendship from those who were ultimately convicted today.
"Those individuals, whom she thought of as friends and with whom she drank in companionship, turned on her in the most violent terms.
"It beggars belief that Jack then went on to attempt to dismember her body in a sinister bid to hide their actions and that they concealed her body for a matter of days while they continued to come and go from the flat in which they had carried out their savage attack."
Laura Milne's relatives said they were devastated at her death
He went on: "None of the accused had any police record to speak of - so for all three to have become so involved in this type of crime is highly unusual.
"Laura was a friendly, outgoing young lady who was popular with her close circle of friends. She kept daily contact with her father by telephone until her death and our thoughts are still with him as he comes to terms with her death."
Det Chf Insp Cooper said that the manner of death and the "harrowing scene" with which officers were faced had caused distress.
He said: "It is a testament to their dedication and professionalism, and close working with the Crown Office Procurator Fiscal Service, that this matter reached a successful conclusion."
Relatives had said in a statement at the time of her death: "We are extremely distressed by the death of Laura who we loved dearly and will miss dreadfully."
