Forensic Science

post img

Forensic science is a multi-disciplinary subject that applies a broad spectrum of sciences to answer question of interest in legal systems. It uses highly developed technologies in discovering scientific evidences used in the courts of law. This can help in a wide range of situations such as laws or regulations violated for marketing food and drugs, manufacture of medicines, and automobile emissions. However, forensic science is commonly used in crime scene investigations such as robbery, assaults, rape, and murder. A number of sub-disciplines in forensic science are currently being practiced which include criminalistics, forensic economics, forensic entomology, forensic ballistics, and forensic engineering. Forensic scientists work in laboratories, crime scenes, or morgues and they may work for the government, police departments, forensic laboratories, hospitals, and universities.




DNA PROFILING

DNA Profiling is a powerful tool for identification by using the characteristics of DNA. DNA is obtained from a person or a sample of bodily tissue. Human DNA profiles can be used to identify the origin of samples found at a crime scene or for parentage testing.

TOOL MARK EXAMINATION

Tool mark identification examines the mark left within the scene – how it was formed by a distinct tool used to commit the crime.

FORENSIC TOXICOLOGY

Forensic toxicology is the investigation of toxic substances usually handles tests on the presence of gases, alcohol, drugs, metals, and chemicals. It is applied in a wide range of situations such as drug and alcohol tests, sexual assaults involving the use of drugs, and testing of body fluids and tissue samples during autopsies.

AUDIO AND VIDEO FORENSICS

Audio and video recordings provide real-time accounts that investigators can hear or watch what is transpired. When high quality audio or video evidence is not available, forensic experts can enhance the recordings and bring out details to provide more audible audio and more clearer picture.

BLOODSTAIN ANALYSIS

Bloodstain left behind can draw conclusion as to how the blood was shed. These stains may appear at random distribution at crime scenes however, it can be analysed by the spatter patterns, transfers, voids, and other marks in recreating the events that caused the bloodshed.

SEMEN ANALYSIS

DNA analysis for semen starts with identifying a stain as seminal fluid though the use of alternative light source like laser. It is important to determine if a sperm cell is present in the stain in order to identify the suspect. Sperm is identified through staining and microscopy.

HAIR AND FIBER ANALYSIS

Hair and fiber are important resources in forensic science and are often responsible in identifying the culprit of a crime. The discovery of hair can determine the race and sex while the fiber can help determine the type of clothing of a person. However, a full detailed microscopical comparison with known sources of hair and fiber should be done prior to DNA analysis.
