1. Situation: An unusual increase in deaths or medical incidents to exceed statistical averages 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 tendency: The suspect has no prior record of violence, antisocial behaviour or mental illness.
