It uses advanced imaging and pattern recognition technology to compare unique markings left on ammunition during firing, known as ballistic fingerprints.
AFIS creates a database of these markings, allowing investigators to quickly match evidence from a crime scene to firearms used in previous incidents. This helps link crimes, identify weapons, and trace their origins.
Widely used by law enforcement agencies, AFIS enhances the speed and accuracy of firearm investigations, making it a vital tool in combating gun-related crimes.
# PROTEOMES IN FORENSIC SCIENCE:-
Proteomes encompass the entire collection of proteins produced by a cell, tissue, or organism under specific conditions. In forensic investigations, proteomics—the large-scale study of proteins—has emerged as a powerful tool to complement DNA analysis. Proteins are more stable than DNA in certain environments, making them particularly useful when DNA is degraded due to time, heat, or environmental exposure.
One key application of proteomics in forensics is the identification of bodily fluids such as blood, saliva, or semen based on specific protein markers. Additionally, proteomics can help estimate the postmortem interval (PMI) by studying the degradation patterns of proteins in tissues, aiding in determining the time of death. Other potential uses include analyzing proteins in hair or bones to provide information about an individual’s health, lifestyle, or geographical origins.
Cutting-edge techniques like liquid chromatography and mass spectrometry allow for the precise detection and analysis of proteins, even from minute samples. As proteomic databases expand and technology advances, proteomes are expected to play an increasingly important role in solving complex forensic cases, especially in areas where traditional methods face limitations.
#FORENSIC DNA ANALYSIS AND NEXT GENERATION SEQUENCING(NGS) :-
Forensic DNA analysis has been a groundbreaking tool in solving crimes, identifying victims, and exonerating the innocent. Traditional DNA methods, such as short tandem repeat (STR) profiling, have been instrumental in criminal investigations due to their high accuracy in matching DNA to specific individuals. However, conventional methods have limitations, particularly when dealing with degraded, mixed, or low-quality samples often found at crime scenes.
Next-Generation Sequencing (NGS) is revolutionizing forensic DNA analysis by addressing these challenges and providing a broader range of applications. Unlike traditional methods, which focus on specific STR markers, NGS enables the sequencing of entire genomes or targeted regions with unprecedented detail. This technology can analyze single-nucleotide polymorphisms (SNPs) and mitochondrial DNA, offering insights into ancestry, biogeographical origins, and even certain physical traits. For example, NGS can help predict eye color, hair color, and skin tone, which can aid investigators in developing a suspect profile.
Another advantage of NGS is its ability to handle degraded or minute DNA samples. By amplifying and sequencing even tiny fragments of DNA, NGS ensures that evidence from older or compromised cases can still yield actionable results. It also excels in analyzing mixed DNA samples, such as those containing contributions from multiple individuals, which is a common challenge in forensic investigations.
NGS is not limited to human DNA; it can analyze microbial and environmental DNA as well. This capability has applications in cases involving bioterrorism, postmortem interval estimation, or identifying environmental sources linked to a crime scene.
Although NGS offers significant advantages, its adoption in forensic science is still evolving. Challenges include the high cost of equipment, the need for specialized training, and the requirement to standardize protocols for court admissibility. Despite these hurdles, the potential of NGS to enhance the accuracy and scope of forensic investigations is immense.
As NGS becomes more accessible and integrated into forensic workflows, it is expected to transform the field. By providing comprehensive, fast, and reliable data, this technology not only advances criminal justice but also opens new avenues for research in forensic science.
# ROBOTICS IN CRIME SCENE INVESTIGATION:-
Robotics is becoming an essential tool in modern crime scene investigations, particularly in situations that are hazardous or inaccessible to humans.
