A Whanganui man died from blood loss after severing an artery in his arm when he punched a window in a rage after arguing with his sister, a coroner has found.
An intoxicated Yusef Vonn Zurich, 25, began arguing with his sister and others at an "out of control" party at a flat where his brother and another sister lived in the early hours of November 2 last year.
Mr Zurich walked away from the fight and went upstairs with his brother and another person.
Still angry, Mr Zurich punched a glass window, severing an artery near his right elbow. Blood began gushing from the wound.
Partygoers, and a nurse who lived nearby, tried to stop the flow of blood and immediately took Mr Zurich to Whanganui Hospital but he died a short time later.
Police initially treated his death as a homicide but concluded that Mr Zurich's injury was self-inflicted, although unintentional.
"I record here that although perhaps some of the goings on at the party were extreme - and contributed in a roundabout way to Yusef's death - everyone appears to have done everything possible to save him once his massive injury was known," Coroner Tim Scott said in his report released this week.
