Forensic science has existed for hundreds of years. However, over the past 100 years, forensic investigations have developed and progress is staggering. Forensic investigation techniques are used every day at crime scenes all over the world. Forensic investigation reflecting the investigation of the crime scene. Investigators at the crime scene reconstruct the crime scene, analyze the evidence, and carefully document the findings of each investigation. If only one of the evidences is incorrectly documented, the entire criminal procedure may be at risk, and the criminal may freely manage the street.
Investigators on the crime scene are particularly trained members of the police. They are the first people of the crime scene and they can only publish property or information only after the investigation is completed. There are various types of forensics that fall into the category of forensic investigation. The simplest type of forensic medicine is a fingerprint. This is when a criminal investigator gathers evidence of fingerprints from the crime scene and analyzes it to obtain fingerprint collation.
Probably the most well known form of forensic investigation is DNA inspection. This test is done by examining physical evidence such as secretions and blood of a crime scene and testing whether it is that of a victim. It is not, but this sample will reveal specific genetic markers including the blood type of the unknown person. For cases such as assault, robbery, rape, homicide, experienced crime scene investigators are important. They are trained on what to look for and how to test the evidence. Even smallest dust and hair can provide rich information to skilled researchers. You can ask whether a single hair found on the crime scene is actually looking for a man or woman for the investigator or whether the hair belongs to the animal.
A trained forensic investigator can eat half an apple and use something like an identification symbol, fingerprint, catch a criminal and catch a criminal who thinks she ran away in criminal behavior. Forensic investigators are used not only to investigate murder cases but also to detect counterfeit items by handwriting analysis and to check the purity of water.
Performing a forensic investigation is a long and complicated process. Beginning with collecting evidence of fingerprints from everywhere on the crime scene, we need to handle everywhere on the crime scene. When fingerprints are printed, it is a cumbersome task to gather every part of dirt, dust, paper, clothing, liquid samples, and all other scenes. In many cases it will take several weeks to process the entire crime scene.
