Jack Frew murder accused Craig Roy 'felt like monster'
The man accused of murdering Jack Frew told a psychiatrist that he "felt like a monster", a court has heard.
Dr Annie Bartlett told the High Court in Glasgow that she interviewed Craig Roy for five-and-a-half hours.
The psychiatrist said Mr Roy had an unspecified personality disorder and showed traits of borderline, dependent and avoidant personality disorders.
Mr Roy, 19, admits fatally stabbing 16-year-old Jack Frew in woods in East Kilbride in May 2010 but denies murder.
Dr Bartlett, who works at St George's University, London, and at Holloway Prison, told the court that she spoke to Mr Roy about his childhood, schooling, family, relationships and the lead up to Mr Frew's death.
Mr Roy told her that he could not remember the attack at all.
Dr Bartlett was asked by defence QC David Burns: "You said he was unable to remember anything about the incident with Jack until he is lying on the ground and he said this gap 'made me feel like a monster'."
She replied: "On discussing this incident he said he felt like a monster. He then said: 'If it was really me, I just don't want to be that person'."
Dr Bartlett said that she diagnosed Mr Roy as having an unspecified personality disorder and added that he had traits of borderline, dependent and avoidant personality disorders.
Speaking of the attack on Mr Frew, Dr Bartlett said: "It seemed to me to indicate a ferocious attack, which according to the pathologist's report, went far beyond that necessary to kill someone. It seemed to suggest a loss of control."
She added: "Mr Roy has no memory of how Mr Frew came to die. Afterwards he is described as being quiet and distressed.
"This represents a ferocious attack. He feels himself unable to remember details while at the same time realising he must have inflicted the wounds."
Dr Bartlett told the court that Mr Roy claimed he was being blackmailed by Mr Frew.
He alleged that the schoolboy, with whom he had oral sex with twice, was threatening to tell Mr Roy's lover, Christopher Hannah.
The psychiatrist also said Mr Roy claimed that Mr Frew was sexually harassing him and he claimed he took a knife to their meeting so that Mr Frew would listen to him.
Dr Bartlett added: "Mr Roy seemed very clear he wasn't able to get his message across that he would very much like not to be propositioned.
"The knife spoke for him as a way of bolstering his confidence about this unwanted and unresolved situation."
The psychiatrist said that Mr Roy told her that Mr Frew never took him seriously and claimed he was "an intimidating person".
Under cross-examination, advocate depute Jennifer Bain, prosecuting, said to Dr Bartlett that her diagnosis did not seem "very definitive".
She replied: "It was not a particularly obvious case".
Dr Bartlett added she was confident of her diagnosis and said: "These are quite subtle judgements. He has got a personality disorder."
She was then asked if somebody could deliberately inflict a large number of injuries and not have a personality disorder and replied: "It would be unusual, but it is possible."
Dr Bartlett was asked by judge Lord Doherty if Mr Roy's ability to control his actions would be impaired or not and she said it was up to the jury to decide.
The trial, before Lord Doherty, continues.
