Twenty-year-old murderer Johnnie Puna has been sentenced to life imprisonment with a non-parole period of 14 years. Puna was 19 when he murdered Mark Beale at Haumoana, Hawke’s Bay, on February 6 last year. He was sentenced in the High Court at Napier on Thursday, following a guilty verdict at the end of a week-long jury trial in November. Beale, 45, was found critically injured near the Tukituki River mouth. He was taken to Hawke’s Bay Hospital, but later died of his injuries. The Crown said Puna became angry after Beale accidentally knocked him over, and killed Beale with a series of punches and kicks to his head over a period of 40 to 60 minutes.
