Study Notes
- Investigators at a crime scene are responsible for identifying, collecting, and preserving evidence.
- Evidence collectors identify, document, and preserve evidence for lab analysis, investigations, and court.
- Special tools may be needed when investigating materials, and incorrect results may result without right tools.
Tools for Crime Scene Investigation
- Infrared Thermometers: Measure surface temperatures to identify heat sources, locate hidden evidence, or determine if an object was recently used.
- Fingerprint Kits: Discover, develop, and collect latent fingerprints from surfaces.
- Storage Jars: Collect and preserve fire debris and ignitable liquids for later investigation.
- Sterile Water Ampoules: Small vials of deionized water to moisten samples before collection.
- Protective Eyewear: Enhances visibility and protects eyes from hazards like chemicals and bright lights.
- Paint Cans: Collect and preserve evidence that may contain accelerants for laboratory testing.
- Notebooks: Document every step of the investigation, including scene conditions, evidence collection, and witness statements.
- Cotton Swabs: Collect potential accelerant residue, including ignitable liquids and trace evidence, from surfaces.
- Arson Evidence Labels: Track, identify, and preserve collected evidence for analysis and court.
- Cameras: Document the scene to determine the fire's origin, cause, spread, and related evidence.
