What tools do CSI use?

These items include:

  • Audio recorder.
  • Biohazard labels.
  • Bloodstain pattern examination kit.
  • Business cards.
  • Backup camera.
  • Chalk.
  • Cutting instruments (knives, box cutter, scalpel, scissors).
  • Directional marker/compass.

What tools are used to analyze evidence?

The instruments commonly used in criminal or environmental forensic investigations and analysis include scanning electron and optical microscopes. These tools are used to characterize forensic evidence like fabrics, metals, textile or glass.

What tools do you need to collect evidence from a crime scene?

A trace evidence collection kit might include: Acetate sheet protectors. Bindle paper. Clear tape/adhesive lift.
A fingerprint kit might include:

  • Black and white film.
  • Brushes.
  • Chemical enhancement supplies.
  • Cyanoacrylate (super glue) wand/packets.
  • Flashlight.
  • Forensic light source.
  • Lift cards.
  • Lift tape.

What is the process of evidence collection?

Trace Evidence

Document and photograph the evidence. Properly secure the evidence by placing it in a paper bag or envelope. Close, seal, or tape the paper bag or envelope. The examiner must initial, date, and time across the sealed area. Label the bag or envelope with the patient’s identifying information.

How do you collect and analyze trace evidence?

When trace evidence is located, it is collected by hand or with a pair of forceps and placed into an appropriately sized packaging, such as a paper bindle. If the location of the trace evidence is significant, record its location by means of a photograph before recovering the item.

What is tool mark analysis?

Toolmark Analysis

This analysis involves tedious microscopic examinations and empirical testing to determine if a mark found at a scene was made by a specific tool. These examinations can be challenging due to the various ways a tool can be held, applied, and used.

What are the various methods used in the collection of trace evidence?

Trace evidence recovery or collection techniques used should be the most direct and least intrusive technique or techniques practical. Collection techniques include picking, lifting, scraping, vacuum sweeping, combing, and clipping.

What techniques can be used for Fibre analysis?

Fiber/Fibre Analysis Techniques

  • Optical Light Microscopy.
  • Atomic Force Microscopy.
  • Scanning Electron Microscopy (SEM)
  • Transmission Electron Microscopy (TEM)

What techniques are used in forensic fiber analysis?

The most common method uses microscopes to examine longitudinal and cross-sectional samples of the fibers. Forensic scientists prefer Scanning Electron Microscopy and Atomic Force Microscopy, which use a beam of electrons or the movement of a microscopic probe, over light microscopy due to the higher resolution.
