The man who mowed down a runner and admitted to murdering her should spend more time in jail for the brutal nature of his crime, the Crown believes.
Matthew Kinghorn, who admitted to murdering 45-year-old Anne Elizabeth McCullough while she was out running on a semi-rural road in New Plymouth in October 2012, is serving a minimum non-parole period sentence of 13 years for the crime.
The sentence, handed down by Justice Rodney Hansen in the High Court at New Plymouth last year, was incorrect, the Crown has submitted.
Today, Crown lawyer Madeleine Laracy argued in the Court of Appeal in Wellington that Justice Hansen committed "errors of law" in deciding on the sentence in December.
At the time, Justice Hansen settled on 15 years as the minimum period of jail, and then discounted that by two years for several mitigating factors - including Kinghorn's guilty plea and appearance of showing genuine remorse.
