Background
A jury found Stefan Lee Hannon-McGinn and Ethan Howe guilty of murdering Sydney Ross Bridson. Howe was also found guilty of arson, while Hannon-McGinn had pleaded guilty to arson at the beginning of trial. The offending followed disputes between Bridson and Hannon-McGinn’s father, who lived on a neighbouring rural property in the Waitaanga Valley.
Early on 11 October 2023, Hannon-McGinn and Howe took firearms to Bridson’s isolated home and called him outside. Hannon-McGinn shot Bridson at close range with a shotgun; Howe encouraged and assisted him and was convicted as a party to the murder. Hannon-McGinn dragged Bridson’s body into the house and set it on fire to destroy evidence, with Howe present and encouraging or assisting the arson. The house, Bridson’s body, and personal belongings associated with Bridson and the homeowner were destroyed.
The Court’s Holding
McQueen J held that the strong statutory presumption of life imprisonment for murder applied to both defendants and that neither case made a life sentence manifestly unjust. The Court found that the murder involved a high level of callousness under s 104(1)(e) of the Sentencing Act 2002 and that Bridson was particularly vulnerable under s 104(1)(g). Section 104(1)(c), concerning unlawful entry into or presence in a dwelling, did not apply because Bridson was shot outside his doorway and neither defendant was unlawfully inside the house.
Although s 104 was engaged, the Court held that its 17-year minimum period of imprisonment would be manifestly unjust for each defendant. Hannon-McGinn, the shooter and instigator, received life imprisonment with a 13-year minimum period; Howe, whose culpability as a party was lower and whose personal circumstances included relevant psychological limitations, received life imprisonment with a minimum period of 10 years and four months. Each also received a concurrent seven-year sentence for arson and a firearms prohibition order.
Key Takeaways
- Life imprisonment for murder is subject to a strong statutory presumption, displaceable where imposing it would be manifestly unjust; the presumption was not displaced here.
- Calling an isolated victim out of his home, confronting him with firearms, burning his body and house, and later concealing and handling the weapons supported findings of high callousness and particular vulnerability under s 104.
- Even when s 104 applies, a 17-year minimum term may be manifestly unjust; the Court differentiated the shooter’s culpability from that of the secondary party and considered each offender’s personal circumstances.
Why It Matters
The decision illustrates that the statutory questions concerning a life sentence and the minimum period before parole eligibility are distinct. It also shows that conduct falling short of unlawful presence inside a dwelling may still contribute to a finding of high callousness when offenders deliberately draw a victim from the sanctuary of the home.
The judgment further demonstrates that equal liability for murder does not necessarily require identical minimum terms. A party’s lesser role, together with causally relevant personal factors, may justify a materially shorter minimum period than that imposed on the principal offender.
