An Auckland painter thought he was breaking up a fight, but as he got closer he saw one man was being stabbed and a woman lying dead on the ground.
Zane Paki, a husband and father, said he acted instinctively to stop Mandeep Singh, who had just murdered his wife before turning on her friend in the foyer of a central Auckland language school in May.
Singh, 29, was yesterday sentenced to life with a minimum parole period of 13 years for killing his wife, Parmita Rani, 22, and stabbing her friend who he suspected she was having an affair with, Parminder Sandhu, who was also 22.
Mr Paki had just signed in at the reception of the AWI International Education Group where he was to do some painting, and had gone outside to get his gear.
When he returned to the third floor of the Queen St building, the doors opened and he was met with chaos.
