The Court sentenced the offender to 22 years' imprisonment with a 16-year non-parole period for the murder of his informal carer by repeated hammer blows to the head. Verdins limb 5 (imprisonment more burdensome due to mental impairment) was engaged, but limbs 1, 3 and 4 were not established because Dr Barth's evidence fell short of demonstrating a causal connection between the offender's schizophrenia and the offending. The Court held that the distinction between an intent to kill and an intent to cause really serious injury was, on the facts, of little weight in assessing moral culpability, and that equivocal evidence about the state of the relationship with the victim at the time of offending was insufficient to establish provocation or a significant relationship of violence contributing to the offence.
