Why Use UV Flashlights at Crime Scenes?

UV light reveals substances that fluoresce under ultraviolet wavelengths. These can include organic materials, chemical residues, and synthetic fibers, which are often pivotal in solving cases.

Step 1: Selecting the Right UV Flashlight

Choosing the correct flashlight is crucial for effective evidence detection. Consider these factors:

Step 2: Preparing the Crime Scene

1. Darken the Area: Reduce ambient light to enhance fluorescence visibility.
2. Wear Protective Gear: UV light can damage skin and eyes. Always wear UV-blocking goggles and gloves.
3. Document the Scene First: Capture initial photos in natural light to maintain context.

Step 4: Documenting Evidence

1. Photograph Evidence Under UV Light: Use a camera with UV filters to capture clear images.
2. Mark Evidence Locations: Use tags or markers for easy identification.
3. Log Observations: Record details about the evidence, such as type, location, and fluorescence color.

Step 5: Collecting Evidence

• Use Sterile Tools: Minimize contamination with tweezers, swabs, or gloves.
• Store Properly: Place collected items in UV-protected, labeled containers.
• Maintain Chain of Custody: Record all handling details to ensure evidence integrity.

1. Understanding the Role of UV Flashlights in Forensic Investigations

UV flashlights are widely used in forensic investigations to detect materials that fluoresce under ultraviolet light. These include:

• Biological Evidence: Bodily fluids (blood, saliva, sweat, semen).
• Trace Evidence: Fibers, fingerprints, and gunshot residues.
• Counterfeit Evidence: Fake currency, altered documents, and forged artworks.

By emitting UV light of specific wavelengths, these flashlights help investigators quickly identify critical evidence, even in challenging environments.
