What are the components of a proper crime scene investigation?

A proper crime scene investigation consists of several critical components that ensure the integrity of the investigation and the collection of reliable evidence. The correct answer includes securing the scene, collecting evidence, and documenting findings, which are all foundational steps in the process.

Securing the scene is vital to prevent contamination or alteration of potential evidence and to ensure that the scene remains intact for the investigation. Properly securing the area helps preserve the scene for thorough examination and protects it from unauthorized access.

Collecting evidence refers to gathering physical materials, such as fingerprints, DNA, and other relevant items. This step is crucial as it provides tangible proof that can be used in legal proceedings. Evidence must be collected and handled according to established protocols to maintain its integrity and chain of custody.

Documenting findings involves recording observations, creating sketches, and taking photographs. This documentation is essential for creating a reliable record of the scene and the evidence collected. It allows investigators to review the scene later and provides a clear account of the investigation process.

While identifying witnesses and interviewing them, as well as addressing media exposure, are also important aspects of an overall investigation strategy, they do not encapsulate the primary components necessary to conduct a proper crime scene investigation.
