Laura Milne was murdered by Stuart Jack in Aberdeen
A man who murdered a teenage charity worker then cut up her body and hid it boasted in a mobile phone video he had enjoyed doing it.
Stuart Jack, 22, smiled as he spoke of killing Laura Milne and mutilating her.
Jack admitted murdering Ms Milne, 19, at a flat in Aberdeen's Union Street last year.
The details of the crime were heard at the High Court in Edinburgh. Sentence was deferred until later this month for background reports.
On Tuesday, Jack had also admitted attempting 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. They also admitted trying to hide the victim.
The phone recording was played to the court on Wednesday.
In the video, Buchan was seen putting her face towards the camera and saying: "This is the new and improved Laura Milne."
Jack replied: "Yes, she certainly is."
Buchan asks: "Did you enjoy cutting her throat?"
Jack replied: "Aye."
In the days after the killing, the trio made various phone calls and text messages to family and friends confessing they had been involved in Laura's death.
Jack boasted in the video about how he had enjoyed slitting Laura's throat
Buchan, who had known her since school, told an ex-boyfriend she had been fighting with a female who was now "lying there looking funny" and Mackinnon told a friend she had been present at a flat when a "girl had been killed".
Jack, who lived at the homeless hostel where Ms Milne worked, told two female residents he had "killed Laura" with a bread knife because she had said she was glad his granddad and sister were dead.
He told them Buchan and Mackinnon had beaten Ms Milne up, then he had gone through to the kitchen, grabbed a knife and cut her throat, and had then cut her head and legs off and that her body was in a cupboard in the flat.
He later told police he had decided to cut his victim up after failed attempts to get the body into the loft.
Jack took the women to the flat, opened the letterbox and said: "Can you smell her body? She is lying in there dead."
The women alerted police, who searched the flat and found Ms Milne's decomposing body wrapped in bedding in a kitchen cupboard beside the sink.
Ms Milne was brought up by her father Brian in Ellon, Aberdeenshire, and has an older brother and younger sister.
She had been diagnosed with mild learning difficulties and was living at the Stopover homeless accommodation in Aberdeen, where she was working as a volunteer in the kitchen.
Advocate depute David Young, reading out an agreed version of the events, said Laura was a "vulnerable, naive and easily manipulated" young woman.
In the days after her death, Buchan had replied six times to text messages from Ms Milne's family pretending to be her, in which he said: "I am fine I am staying with a friend and yes you will see me", said Mr Young.
Laura Milne's father earlier said she was too trusting and could not see the bad in people.
Brian Milne said his daughter was a "lovely young woman with a big heart". He added that she was always willing to help others.
Mr Milne said: "We continue to miss Laura every day - she was a major part of our family and it was rare for a day to pass without her being in touch with us. She was always on the phone or visiting us.
"Laura was a lovely young woman with a big heart.
"She was always willing to help others and this was reflected in the work she did with the Cyrenians [homeless charity]."
He explained: "Her failing was that she was too trusting and could not see the bad in people."
