Today marks the 12th anniversary of the death of Senior Constable Len Snee, who was fatally shot by Napier cannabis grower Jan Molenaar.
Fellow senior constables Grant Diver, Bruce Miller, and civilian Len Holmwood, were also shot and seriously wounded.
The three officers arrived at Molenaar's Chaucer Rd, Napier, home to conduct a search on the morning of May 7, 2009.
In the ensuing deathly rampage, Molenaar fired dozens of shots around the valley on the Napier side of hospital hill, and a considerable area of Napier was put into lockdown.
The siege lasted 51 hours before cautious, armed and heavily protected officers entered the house and found Molenaar had taken his own life.
