TS 12770

TS 12770 is a professional standard for personnel working as police officers in crime scene investigation. In criminal justice practice, careful handling of the scene is essential because physical traces can be lost, contaminated, or mixed if they are not managed methodically. This standard covers the police officers who perform that specialist function and helps define the competency framework for the role.

What crime scene investigation means in technical terms

Crime scene investigation is the systematic identification, recording, preservation, and transfer of material traces after a crime or other legal incident. In general technical context, this includes separating and assessing fingerprints, biological traces, tool marks, trace evidence, and other physical findings as distinct items of evidence. Effective scene work depends not only on observation, but also on disciplined documentation, careful classification, and preservation of evidential integrity.

The professional scope covered by this standard

Based on the stated scope, the standard covers police officers who carry out crime scene investigation duties. The referenced legislation and related regulations connect this role with police judicial duties, collection and safeguarding of evidence, identity determination, and the organisation of crime scene examination. As such, the document is relevant to the specialist occupational function of forensic scene work rather than to general policing duties.

• Locating and protecting physical evidence at the scene
• Maintaining recording and preservation practices for forensic review
• A specialist role linked to identification and examination procedures
• A professional framework connected to police judicial duties and evidence handling
