How does a crime scene investigation work?
We’ve all seen the TV shows, whether we watch them religiously or catch them when there’s nothing else to watch. The question is, how accurate are they? Though every crime scene is unique, investigators follow a typical chain of action:
- After the police secure a scene for analysis, investigators arrive and begin with a visual examination of the area. They will ask what has changed about the scene, whether anything has been touched, and make note of potential evidence without touching it.
- Before physically collecting data, investigators will thoroughly document the scene via photographs and drawn sketches. Nowadays, this may also include a video walk-through.
- Investigators will then use extreme care to collect any and all potential evidence, packaging and labeling it so that it survives its trip to the lab.
- The processing of evidence is known as forensic science. Results are found in a lab and sent to the detective leading the investigation.
Why do I need a private investigator who can act as a crime scene analyst?
Most law enforcement agencies hire their own crime scene investigators, but sometimes a second opinion or more thorough investigation can save you from false charges or help you prosecute a criminal. Hiring a private investigator can help you determine what happened and ensure you have the answers you need. If you are involved in a court case, a private investigator can get you reputable evidence that stands in court.
