"There is, in my opinion, very little doubt that Mr Turner has a psychotic mental illness. This is, in my opinion, a mental disorder which, at its core, resembles schizophrenia but includes significant symptoms affecting his mood (of affect) so that the eventual diagnosis may be schizoaffective disorder or schizophrenia. Cannabis has undoubtedly played a part and may have contributed to both the development of his mental illness and at times worsened or maintained symptoms..."
"Mr Turner's mental illness is the most important factor in understanding this offence. He was, in my opinion, suffering from an abnormality of mental functioning arising from a recognised medical condition..."
"... that his abnormal mental function substantially impaired his ability to both exercise selfcontrol and form rational judgments..."
"In terms of diagnosis, in my opinion Liam Turner is suffering from a schitzoaffective disorder with affective (depression, elation, overactivity) and psychotic delusions ..."
"I reject the suggestion that the defendant is suffering from a mental illness, for example schizophrenia or a schitzoaffective disorder ..."
"I acknowledge, in my second report, that I cannot rule out the possibility that the defendant suffers from a schizoaffective psychosis. This is because psychiatry is an inexact science and it is often to rule out diagnosis entirely. However, when looking at all the circumstances surrounding the killing, it is more likely that the defendant's behaviour at the time was due to personality structure, interacting with voluntary intoxication, rather than due to schizophrenia affective psychosis. Hence I reject that diagnosis when considering the defence of manslaughter on the grounds of diminished responsibility."
"I find ... his behaviour was as a result of anti-social personality traits, coupled with his anger and stress and possibly exacerbated by cannabis and alcohol consumption ..."
"In my view it did, but only to a small extent. The mental health disability from which Mr Turner was suffering would have been significantly improved had he co-operated with the mental health professionals by taking his medication ..."
"... I accept that this mental health disorder was a contributory factor to his behaviour in April, even though it falls short of a statutory defence and even though much of the culpability for his mental health contributing to his behaviour lies with him."
"...has always accepted the facts of what took place, without seeking to mitigate."
"Where the sentencing court is satisfied that there were particular circumstances which significantly reduced the defendant’s ability to understand what was alleged or otherwise made it unreasonable to expect the defendant to indicate a guilty plea sooner than was done, a reduction of one-third should still be made. In considering whether this exception applies, sentencers should distinguish between cases in which it is necessary to receive advice and/or have sight of evidence in order to understand whether the defendant is in fact and law guilty of the offence(s) charged, and cases in which a defendant merely delays guilty plea(s) in order to assess the strength of the prosecution evidence and the prospects of conviction or acquittal."
"This analysis should not be taken as indicating that in every case of murder, pursuing a defence of diminished responsibility should not deprive a defendant of credit as if a guilty plea had been entered at the first available opportunity. In most cases, a defence of diminished responsibility depends on a version of facts which in large part emanates from the defendant; if those facts are rejected by the jury, there should be no question of credit for admitting manslaughter beyond that which is identified in para. 11(c) of Schedule 21 to the 2003 Act ('mental disorder or mental disability which (although not falling withinsection 2(1) of the Homicide Act 1957 ), lowered his degree of culpability'). Furthermore, depending on the nature of any disorder or disability, adults will be in a different position to children, and more likely to be able to make informed decisions based on an assessment of the evidence. The facts in this case are very unusual, and must be seen as such."
"Each case must be considered on its own merits ..."
