ABSTRACT:
In this article, we will discuss about the analysis of criminal cases in forensics. The analysis of criminal cases involve several steps, through which investigation become reliable. This revolutionized the investigation and forensic sciences. DNA profiling and analysis, fingerprint and ballistic examination are included in these techniques. These techniques were first used in 19th century to capture a murderer.
INTRODUCTION:
Forensic science plays a crucial role in the investigation and analysis of criminal cases. By utilizing scientific methods and techniques, forensic experts analyze evidence to uncover the truth, identify perpetrators, and ensure justice is served. This article aims to explore the study and analysis of criminal cases in forensics, highlighting the significance of various forensic disciplines and their contributions to solving crimes. https://www.crime-scene-investigator.net/csi-articles.html
1. DNA ANALYSIS:
DNA analysis has revolutionized the field of forensics, providing irrefutable evidence in criminal investigations. By comparing DNA samples collected from crime scenes with those of potential suspects, forensic scientists can establish connections and identify individuals involved in the crime. The accuracy and reliability of DNA analysis have led to countless convictions and exonerations, making it a cornerstone of modern forensic investigations (Butler, 2015).
2. FINGERPRINT ANALYSIS:
Fingerprint analysis has been a fundamental tool in forensics for over a century. Each person possesses a unique pattern of ridges and furrows on their fingertips, making fingerprints an invaluable piece of evidence. Forensic experts use advanced techniques to, and match fingerprints found at crime scenes, aiding in suspect identification and linking individuals to specific locations or objects (Champod et al., 2017).
3. BALLISTICS AND FIREARMS EXAMINATION:
Ballistics and firearms examination involve the study of bullets, cartridge cases, and firearms to determine their involvement in a crime. Forensic experts analyze the unique markings left on bullets and cartridge cases, known as toolmarks, to link them to specific firearms. This analysis can help establish the type of weapon used, its potential owner, and even the sequence of shots fired, providing crucial evidence in criminal investigations (Franco et al., 2018).
4. FORENSIC ANTHROPOLOGY:
Forensic anthropology focuses on the identification and analysis of human remains in criminal cases. By examining skeletal remains, forensic anthropologists can determine the age, sex, stature, and potential cause of death of an individual. This information aids in victim identification, establishing the timeline of events, and providing crucial evidence in homicide investigations (Stewart, 2018).
5. DIGITAL FORENSICS:
With the rise of technology, digital forensics has become an essential component of criminal investigations. Digital forensic experts analyze electronic devices, such as computers, smartphones, and hard drives, to recover and examine digital evidence. This includes retrieving deleted files, analyzing internet browsing history, and uncovering communication records, all of which can provide valuable insights into a suspect’s activities and intentions (Casey, 2018).
CONCLUSION:
The study and analysis of criminal cases in forensics have significantly advanced the field of criminal justice. Through the application of various forensic disciplines, investigators can uncover crucial evidence, identify perpetrators, and ensure justice is served. The accuracy and reliability of forensic science techniques have played a pivotal role in solving countless criminal cases, making it an indispensable tool in the pursuit of truth and justice.
