How to investigate a crime scene: unravelling the mystery.
The arduous process of forensic investigation begins after a crime has been committed. It's a journey into the unknown, gathering clues to unravel the mystery. A detailed look at the essential steps in investigating a crime scene.

1. Protecting the environment. 
Securing the crime scene is the first and most crucial step in avoiding contamination and loss of evidence. Law enforcement officers tape off the area, limit access, and ensure that only authorized personnel enter. The integrity of the scene depends on this step.

2. The preliminary survey is underway.
The principal investigator conducts a preliminary investigation after the location is secured. The scene's layout, potential evidence, and a plan for a more detailed investigation are all involved in this assessment. Photographs and notes are taken to document the scene as it was found.

3. Documentation
Detailed documentation is essential. Investigators take comprehensive photographs from various angles, create sketches, and write detailed notes. This step ensures that every detail is captured for future analysis and courtroom presentation.





4. Evidence Collection
Carefully and methodically, investigators collect physical evidence, which could include anything from bloodstains and fingerprints to weapons and Fibers. Each piece of evidence is meticulously catalogued, photographed, and placed in appropriate containers to prevent contamination. 



5. Evidence Preservation
Preserving evidence in its original state is paramount. This involves proper packaging, labelling, and maintaining a chain of custody to ensure that the evidence remains intact and its integrity is upheld throughout the investigation and trial process.

6. Crime Scene Reconstruction
With all the evidence collected, investigators start piecing together the events leading up to, during, and after the crime. This process involves analysing the evidence, considering witness statements, and using logical reasoning to reconstruct the sequence of events.

7. Analysis
The collected evidence is sent to forensic labs for analysis. Here, experts examine DNA, fingerprints, ballistics, and other forms of physical evidence to link suspects to the crime scene or victim. This
scientific analysis is crucial in forming a clear picture of what transpired.
