It was in 2015 that Faraniko Pei went on a shooting rampage in Palmerston North, targeting police stations.
His reason was he thought his sister Edna was not receiving adequate care from MidCentral District Health Board.
Now, for the first time, Edna has spoken out about the ordeal.
"As a child I was always told, or treated for severe asthma. At the age of 11, I was diagnosed by Greenlane Hospital with bronchiectasis which is a lung disease, which basically means there is a whole bunch of holes in your lungs and it breeds bacteria," says Miss Pei.
Over the next 30 years, Edna's health declined to the point where she couldn't stay away from hospital, for more than a month.
