Saturday morning, 14 March 2009. An 80-year-old woman in Helsinki is given yoghurt by the nurse who shops for her, walks with her, and is meant to keep her alive. The yoghurt tastes bitter. Minutes later she is slipping under — and the same nurse picks up the phone and calls emergency services herself.
This episode of A True Crime Podcast follows host Alexander Lawson into the case of Aino Nykopp-Koski, the Finnish practical nurse later known as myrkkyhoitaja: the poison nurse. Between 2004 and 2009 she was convicted of murdering five elderly patients and attempting to murder five more, using sedatives and opiates that were never on their charts. Then she called for help.
Lawson traces the years the deaths looked ordinary, the thefts that rode alongside the poisonings, the cluster of fatalities at Kannelkoti, the graves Finnish courts ordered opened, and a life sentence she has never accepted. No clean motive. No confession. A healthcare system built on trust, used as a key to the door.
Look after the people who look after you. And if the yoghurt tastes bitter — say so.
