How You can be a Forensic Investigator?

By,
Dr. Bhoopesh Kumar Sharma

One of the first person to visit the scene of a crime is a crime scene investigator, and the evidence he collects helps determine the course of the investigation. Some times, he might derail or delay the investigation if he disturbs the crime scene or misses a crucial clue. Therefore, investigators in the crime scene must be thorough, methodical, and stay calm under pressure. He must possess an array of certain qualities. Few of these are mentioned below.

Crime Scene Investigator

Investigators of the crime scene must remain impartial, concentrated and not involve themselves emotionally, or allow their judgement to be clouded or affected.

Despite the severity of the crimes they investigate, they have to methodically approach each case, concentrating on unraveling the sequence of events. This can trigger emotional and physical stress that can take a significant toll before they learn to cope with each day's trauma.

What Skills You Need to Become an Investigator?
How to be a forensic investigator?


1. Analytical & Observatory Skills: Investigators of the crime scene, or CSIs, have critical specialist expertise. They are able to examine a crime scene by observation, formulate hypothesis about how the different pieces of evidence fit together, and follow up on key details. For this, you need a strong scientific background and working knowledge of the various evidence-gathering techniques and tools.



2. Good Communication Skills: You've got to have great communication skills. You often lead a team of laboratory technicians and other law enforcement officers when investigating. Normally, the CSI works to cordon off the crime scene to prevent destroying evidence. They are also reviewing the evidence with other police efforts to collect evidence and testimony from witnesses. CSIs may sometimes act as expert witnesses in a court case to map out the crime scene. Writing skills are also important. Investigators take notes and file detailed case reports used in court cases by prosecutors.

3. Be Poise: Poise under pressure is a vital attribute for investigators in the crime scene. CSIs investigate regularly horrific crime scenes involving brutal murders and lots of blood. Your one simple mistake under pressure can ruin the crime scene completely. Most importantly, when working around a horrific scene, you need to stay calm and focused on gathering evidence. In some larger communities or high-profile situations, you may need to remain prepared with local media and residents.


4. Problem-Solving Skills: Investigators are usually natural problem solvers. They have been trained to do so by different brain storming exercises and reasoning technologies. To compile evidence and testimony, they combine science aptitude, analytical skills and critical thinking. Essentially, CSIs are trying to develop stories based on their interpretation of facts and circumstantial case theories. It helps to determine the motive and the possible reason the crime occurred while interacting with other police and the district attorney. In court, lawyers need to tell stories to persuade judges and juries to see the evidence.

5.  Be Ready Anytime: The investigator must be flexible in working as they never know where their work will take them. They must be sufficiently adaptable to function in the most complex and severe environments. However, they sometimes have to work long hours, particularly when investigating mass casualty scenes or when trying to gather evidence before it is polluted by imminent rain, for example, or by the public, especially in places such as office buildings or other public spaces that need to be reopened quickly.

6. Be Honest & Ethical: Investigators must be honest, ethical and respectful of the law. If an investigator is caught lying or using deceptive research tactics, he will lose credibility and probably his work. This is a concern if the case goes to court and the defendant may be kept from being convicted.



7. Technical Knowledge: Throughout their investigations, investigators often use technology for assist. Based on the type of inquiry, the equipment varies and the company or organization for which the investigator operates. For examine evidence such as fingerprints, it may include surveillance equipment and software.

8. Legal Knowledge: Investigators need to know the laws of the case and the law applicable as per the country specific for that particular crime. For example, an investigator can find the organization is doing something that is ethically questionable, but not illegal, while looking into a business. Therefore, they need to know what they are legally permitted to do during their study.

The Crime Scene is search for the physical evidences (visible or invisible). There are various types of search methods employed by the investigating officers and the forensic scientists at the scene of crime. The searching methods mainly depends on: Type of Crime (Rape, murder, burglary, theft, etc.) Nature of Crime (Homicide, suicide, or accident) Size of the crime scene (macroscopic or microscopic) Location of the crime scene (indoor, outdoor, combination of indoor or outdoor, or any remote area like underwater, desert, etc.) Complexity of the crime scene  Before deciding the search method, all the investigators and the forensic experts must follow the general guidelines (check list) to observe the crime scene after due recording: 1. Are the doors and windows locked or unlocked? Open or shut?  2. Are there signs of forced entry, such as tool marks or broken locks? 3. Is the house or the crime scene is in good order? If not, do

The flight path of a bullet includes:  • Travel down the barrel  (Internal Ballistics), • Path through the air  (External Ballistics),  and  • Path through a target  (Terminal Ballistics) Forensic Ballistics: Is that branch of forensic science which deals with the examination of the firearm and related evidences encountered at the scene of crime in a shooting incident, and their linkage to the firearm, and Identification of the shooter.

Blood Spatter Analysis

What is Blood Spatter Analysis? Blood Spatter Analysis or Blood Pattern Analysis (BPA) is the examination of bloodstain shapes, locations, and distribution patterns, to provide an interpretation of the physical events that gave rise to their origin. In forensic investigations, it is ubiquitous to encounter blood on the crime scene. This blood can be in the form of a pool, dried stains, spatter, expirated blood, etc. Hence, the investigators are required to understand these bloodstains to interpret the events that have occurred on the crime scene, to create a possible hypothesis of the modus operandi, to identify the type of weapon, the direction of the blow, severity of the injury, applicable forces, etc. This whole interpretation is known as Blood Pattern Analysis or Blood Spatter Analysis. What are the Types of Blood Patterns? There are many classifications given by blood spatter analyst around the world. I will be using the most common here, to make it understand in
