How It Works - Crime Scene Investigation
The crime scene is the intersection of logic, law and science. Processing a crime scene is a tedious and lengthy process that involves objectively documenting the conditions at the scene and collecting physical evidence that will likely shed light on what happened and point to who committed the crime.
At any crime scene, a crime investigator can collect a smear of dried blood on a window, test a hair from a victim's jacket without touching the glass with their hands, if there are any unseen fingerprints. Squeeze some white powder (which may or may not be cocaine) into a piece of tweezers, but don't disturb the fabric, and use a sledge hammer to smash the wall that appears to be the source of the horror. the smell
Physical evidence itself is a part of the investigation. The ultimate objective is the conviction of the person responsible for the crime. Therefore, when the crime investigator tears off a patch of dried blood without staining a few prints, picks up several hairs without leaving any trace of evidence, and breaks down a room partition, he thinks of all the procedures necessary to preserve all the evidence. In its current form a crime lab will do some legal work involving reconstructing crimes or identifying the perpetrator or perpetrators and ensuring that evidence is admissible in court.
A crime scene begins when the criminal investigation unit receives a call from a police officer or detective at the scene of a crime. After arriving at the crime scene, the investigator confirms that the place is safe. He then does a preliminary walk-through to get a full feel of the crime scene, see for himself if anyone touched or touched anything in his arrival, and then he develops a preliminary theory. Visual assessment. He then notes some possible evidence. In this case, he does not touch anything.
The crime scene investigator carefully documents the crime scene by taking photographs and making sketches during a second or subsequent walk-through. Sometimes, the document period also constitutes a movie walk-through. The investigator thoroughly documents the crime scene and records what they determine to be evidence. Until this moment, the researcher does not touch anything.
After documentation, the investigator systematically and very carefully goes through the crime scene and collects, tagging, logging and packaging all the important evidence so that they are intact when they go to the crime lab. The crime lab then processes all evidence collected by crime scene investigators. After the lab results are ready, they send the case to the detective.
Each scene in the Criminal Investigation Unit bridges the gap between field and laboratory work in different ways. Crime scene analysis or crime investigation goes to the crime scene and what happens in the laboratory department is called forensic science. Since not all crime investigators are forensic scientists, they must have an excellent understanding of forensic science in order to be familiar with the special value of different types of evidence when working in the field. The scene of crime investigation is a very big undertaking so it is essential to have the necessary qualifications for the post of a crime investigator.
