Police have confirmed a Nelson man suffered a "very violent attack" which led to his death.
Detective Senior Sergeant Craig Johnston said a post mortem on the body of John Murray 'Muzza' Morton was completed in Christchurch yesterday and confirmed they will now be treating his death as a homicide.
"The number and nature of Mr Morton's injuries suggest a very violent attack and the investigation team is determined to piece together exactly what happened," he says.
Morton, 55, died overnight on Wednesday and lived in one of three boats that often frequented the Nelson Haven area.
However, his body was not found in his own boat when he was discovered on Thursday morning.
