The best thing to see if you are fit for a career as a crime scene investigator is going through the job description. CSI’s have a special place in law enforcement divisions. A crime scene detective job description will help you decide whether you are fit for this job or not. The scenarios shown on TV might differ to a great extent from the real life job experience.
Crime Scene Investigator- Job Description
1. Gather Evidence
- The first thing a crime scene investigator does is collect evidence at the crime scene.
- He collects physical evidence and takes plenty of photographs of the crime scene.
- Evidence, or the lack of it, is equally important.
- For e.g, if someone reports a robbery and there is no evidence of forced entry, that too is evidence.
- Gathering evidence from a crime scene can be a tedious task, taking several hours, and a crime scene investigator must be alert to avoid overlooking any critical evidence.
2. Lab Work
- Evidence collected must be sealed securely to avoid tampering and contamination.
- Each piece of evidence is recorded, including its location, and sealed and sent to the forensic lab.
- Evidence collected by a crime scene investigator is received at the crime labs, where it is checked and tested for any clues.
- They can reveal any DNA clues or give an indication as to how the crime took place.
- A CSI must ensure that the equipment and clues must be handled properly, as improperly handled clues can ruin a case.
- Equipment can be very simple, like tweezers and cameras etc, or very complex, like those used for blood spatter analysis and finding fingerprints and DNA.
- After investigation and collecting evidence, investigators must write down official documents which they can use to testify in courts.
- These reports are then stored for future references.
Due to TV serials, there has been misconception about what crime scene investigators actually do.
- They also do not interrogate suspects. It is the job of case investigators.
