Advancements And Techniques Used In Crime Scene Investigations

The advancements in crime scene investigation have made solving a crime simpler for the crime scene investigators. There are numerous tools used in a crime scene, and the progression of these tools has made the work of an investigator more reliable. Fingerprint equipment, casting equipment, photographic equipment, evidence packing supplies, simple hand tools, blood collection supplies, and miscellaneous equipment are all extremely important and basic advances used in the majority of any crime scene. An example of a reliable and resourceful tool that plays an important role in help solving the crime is the use of starlight. The recovery and detection of possible unseen blood stains at the crime scene can make or break a case. The use of starlight
Without the use of protective gloves, many investigators would have to face a risk. Blood pattern analysis (BPA) is the interpretation of bloodstain at a crime scene in order to recreate the actions that caused the bloodshed. This advancement plays a huge role in bloody crime scenes by assisting investigators with details and important information on the crime. The pattern of the stains give detectives a number of clues including the direction of the blood travel, the origin of the stains, the velocity of the bullet if the victim was shot, whether the victim was moved after death, and if the crime scene was tampered with in any way. BPA provides information not only about what happened at the scene, but also what could not have happened as well. This information helps investigators reconstruct the crime, get statements from witnesses, and also eliminates possible perpetrators involved in the investigation. Photography is another major and obvious advancement that has played a role in solving crimes throughout many years. The advancements in photography have come a long way in the past 30 years, and today we see some of the most impressive and advanced photography used at any scene of a
Forensic technology is the technology used to analyze the details of the crime after it was committed, and provides court details of the crime that may not have been visible at the crime scene. Forensic technology is spreading rapidly, helping investigators and forensic experts solve the most brutal and challenging crimes. There are countless amounts of new forensic technology developed or developing that help investigators and forensic scientists solve the crimes. Forensic carbon-14 dating has been used to identify the age of unknown remains for anthropological findings. This type of technology used in the forensic lab helps investigators in solving crimes where the deceased body of a victim is hard to identify. DNA analysis and fingerprinting both play huge roles in identifying people involved in a crime whether it's the perpetrator or the victim. DNA technology is often the critical factor in prosecuting the guilty and identifying the innocent. DNA can be used to compare a suspect's DNA to DNA from the crime scene. A combined DNA index system, also known as CODIS, is one of the most helpful resources for law enforcement. CODIS allows labs to compare new DNA to previously entered DNA anywhere in any location. Another major part in helping solve crimes is the use of fingerprinting. As fingerprints are unique to each individual, they serve as a way for law enforcement agencies to identify a
