The man convicted of killing a Christchurch teenager two years ago has lost his appeal against his conviction and sentence.
Hayden Miles, who was 15, was beaten to death and dismembered by Gavin Gosnell in August 2011, before his remains were buried in graves in two Christchurch cemeteries.
Gosnell was found guilty of murder after a trial in the High Court at Christchurch last year and was sentenced to life in prison with a minimum non-parole period of 18 years.
He appealed against his sentence on a number of grounds, including that his lawyer had not acted in his best interests and that he had wanted to give evidence.
The Court of Appeal has dismissed the appeal, saying Gosnell's lawyer, Craig Ruane,, handled the trial with commendable professionalism.
