The case par excellence is Harold Shipman, a British doctor, who systematically murdered hundreds of elderly patients by administering lethal doses of medication, exploiting the trust placed in him as their healthcare provider. Other famous cases are a little less edifying for the legal profession:

'''Colin Norris'''
{{l3}}'''Situation''': A cluster of unexplained deaths occurred on Ward 42 of the Leeds General Infirmary, where Colin Norris worked as a nurse. The victims were elderly female patients. <li>
'''Suspicion''': Norris was present during a disproportionate number of patient deaths and collapses. There were concerns about his excessive overtime and his apparent enjoyment of the drama surrounding patient crises. <li>
'''Direct Evidence''': No direct evidence of Norris administering lethal substances or physically harming patients was found. <li>
'''Evidence Implicating Suspect''': A syringe containing insulin was found hidden in Norris's locker. Witnesses reported seeing Norris “acting suspiciously” around patients, including one instance where he was seen injecting a patient.
Norris had conducted internet searches related to insulin poisoning and patient deaths. <li>
'''Evidence of Foul Play''': Post-mortem examinations revealed abnormally high levels of insulin in the blood of some victims. Medical experts concluded that the insulin levels were inconsistent with accidental overdose or diabetic conditions. The pattern of deaths and the victims' profiles suggested a deliberate act of harm.

We characterise “healthcare serial murder” cases as follows:

  1. Situation: An unusual increase in deaths or medical incidents at a controlled hospital or care facility exceeding statistical averages for that facility and for which there is no obvious “innocent” explanation.
  2. Suspect: A given carer or medical professional was present for all the incidents.
  3. No direct evidence: There is no reliable direct evidence of the identified carer actually harming any of the patients.
  4. “Small arrows”: There are many pieces of weak circumstantial evidence pointing to (or at least consistent with) the carer’s involvement, but which, when taken individually, do not strongly implicate the carer.
  5. No motive: The suspect has no apparent motive.
  6. No criminal propensity: The suspect has no record of violence, antisocial behaviour or mental illness other than the alleged offending.

The classic case?

HHarold Shipman, a British doctor who systematically murdered hundreds of elderly patients by administering lethal doses of medication, exploiting the trust placed in him as their doctor is often cited but it wasn’t quite the classic case, as the majority of Shipman’s murders took place away from a medical facility and in the patients’ homes, where there would be no witnesses, security devices or cameras that might record his action. The circumstantial evidence (when people knew to look for it) that implicated Shipman was both overwhelming and strong, and (at least at the end) there was a financial motive — though this might not have been present earlier.
