To ask the Secretary of State for the Home Department, whether murder victims are posthumously (a) drug and (b) alcohol tested as a matter of routine.

Forensic post-mortems follow the Code of Practice issued by the Home Office, the Royal College of Pathologists and the Department of Justice in Northern Ireland, which requires toxicology samples to be taken and preserved where necessary. If samples are not taken and an issue later arises (for example, at trial), it may be difficult to obtain usable material. Whether samples are submitted for analysis depends on the circumstances of the case and local police and coroner policies and decisions. Drug and alcohol testing is usually commissioned where it may help establish the cause of death or support the investigation.
