11 There was no sign of any struggle or disagreement between Ms Harty and yourself before you shot her. There was no evidence at all of anything which could have given you even the slightest reason to contemplate doing her any harm, let alone brutally murdering her as you did. Your murder of Ms Harty was entirely senseless, needless and wanton. The evidence discloses beyond any doubt that this was not a case of a sexual encounter in which, in the heat of the moment, feelings or passions may have led to a spontaneous and irrational act of violence. Rather, and quite to the contrary, this was, most clearly, a callous, craven and senseless murder in cold blood of an entirely innocent, defenceless and vulnerable young woman. The evidence leads to the inevitable conclusion that you murdered Kristy Harty for no other reason than for the sheer sake of it. That factor, and the other factors to which I have already referred, make this a most serious instance of the crime of murder. Indeed, your counsel, on your plea, correctly recognised and accepted that the circumstances of the offence for which you have been convicted are extremely grave.
