In English law, unlawful killing is a verdict that can be returned by an inquest in England and Wales when someone has been killed by one or more unknown persons. The verdict means that the killing was done without lawful excuse and in breach of criminal law. This includes murder, manslaughter, infanticide and causing death by dangerous driving. A verdict of unlawful killing generally leads to a police investigation, with the aim of gathering sufficient evidence to identify, charge and prosecute those responsible.
The inquest does not normally name any individual person as responsible. The standard of proof is that the unlawful killing must be beyond a reasonable doubt. If this standard is not met, a verdict of accidental death or death by misadventure on the balance of probabilities may be returned.
A verdict of unlawful killing was returned in the following notable cases:
- Lt Col Rupert Thorneloe and Trooper Joshua Hammond, of the 2nd Royal Tank Regiment, were killed in an explosion in Helmand Province in Afghanistan on 1 July 2009.
