On February 8 1997 Stephen Anderson went on a shooting spree at his family lodge just out of the small North Island town of Raurimu.
He killed six people including his own father and wounded four before he fled into the bush.
It later emerged that the gunman was a paranoid schizophrenic and regular cannabis whose firearms licence had been revoked by police amid safety concerns.
But at the lodge that fateful day, he accessed a sawn-off shotgun, and did his worst.
