Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.
This is the platform for both those who are interested to provide forensic services as well as those who are seeking these services. Both may get registered freely with us and interact one to one, many to one or one to many. The role of the forensic consultant is to serve as a facilitator in helping the in-house and litigation attorneys understand how to achieve best compliance with the Rules, court requirements, and the goals of the case in using physical evidence. This of course can only be achieved if the attorneys take the necessary step of engaging the services of the consultant.
It is the examination of firearms, discharged bullets, cartridge cases, shotgun shells, ammunition of all types, as well as scrapes and impressions on surfaces made by the firearms. The examination of pistols , revolvers, rifles and shotguns determine whether they are in good shape or operable or capable of accidental discharge. Projectiles recovers from the victim or scene, as well as fired casings are examined to determine whether the ammunition was fired from a particular weapon. In case where no weapon is recovered, an examination of lands and grooves details may indicate the type of weapon utilized to the exclusion of others.
The easy definition of digital crime is “crimes directed at a computer or a computer system.” The nature of digital crime, however, is far more complex. Digital or cyber crime can take the form of simple snooping into a computer system for which we have no authorization. It can be the freeing of a computer virus into the wild. It may be malicious vandalism by a disgruntled employee or it may be theft of data, money, or sensitive information using a computer system. Computer crime—a general term that has been used to denote any criminal act which has been facilitated by using computer. Such generalization has included both Internet and non-Internet activity.
DNA is a powerful investigative tool because, with the exception of identical twins, no two people have the same DNA. Therefore, DNA evidence collected from a crime scene can be linked to a suspect or can eliminate a suspect from suspicion. During a sexual assault, for example, biological evidence such as hair, skin cells, semen, or blood can be left on the victim’s body or other parts of the crime scene. Properly collected DNA can be compared with known samples to place a suspect at the scene of the crime. The effective use of DNA as evidence may also require the collection and analysis of elimination samples to determine the exact source of the DNA. Elimination samples may be taken from anyone who had lawful access to the crime scene and may have left biological material.
The purpose of such examination is to examine biological tissues and fluids and organs they affect for the presence of drugs , poisons, alcohol and other toxic substances. The toxicological findings show whether the victim of a crime died or became ill as a result of a drug or poison ingestion, or in a criminal case if the alleged was under their influence during commission of a crime; to find if the dose of certain medicines was prescribed or the victim was poisoned ; to determine if the case was of accidental, homicidal or suicidal poisoning.
“Forensic chemistry” is a broad term that, if taken literally, would encompass most of the functions within a crime laboratory. Techniques used in forensic chemistry are also used by the toxicology and trace analysis sections. However, forensic chemistry generally refers to controlled substance or drug analysis.To analyze physical evidence, forensic chemistry draws on chemistry principles and concepts. Investigating the physical and chemical properties of a substance is central to forensic chemistry. Without an appreciation for these properties and the scientific method, forensic chemistry would not be possible.
The advancement in the field of forensic sciences, the application of physics is well established and growing day by day research and development. In this context forensic scientists those are working in the field which need specialized knowledge in physics to analyze the items of physical evidences into reports and testimonies in the court of law. Knowledge of analysis of the evidence is required in physics as in important and fundamental subject to be studied to the forensic scientist. So that, in part, sets the limits of its interpretation within the physics laws and applications.
The crime scene is not the domain of anyone but of the whole team. A scene of occurrence of a crime is the place where a particular crime has been committed or where physical evidence of such crime is found or taken place and first brought to the notice of the police. Thus, there are multi-point crime scenes in most of the cases. It is the starting point for the investigator, which provides him with the information on the victim and the suspect and to reconstruct the crime scene . In short, crime scene is a site where some evidence relating to the commission of crime is found or exchanged. It is a place where the person/persons involved conducting a crime. The scene occurrence provides a wealth to clue material and other evidence . The scene of occurrence of crime cannot be limited to one specific place; it may extend to more than one place. It may also not be limited to the surroundings but thus it extends to a wider area depending upon the nature of crime. Every Crime scene leaves a unique way of aspects for the examination of the scene. The opportunity to examine the crime scene of occurrence is available only once. If the same is not investigated properly the wealth of information is lost forever.
Forensic Biology is the umbrella term for the biology involved in crime scene investigation. It entails a little bit of everything – from histology and microbiology, to entomology and botany. A forensic biologist is one who examines just about every biological trace of evidence in the crime lab. He or she must analyze bodily fluids, bones, insects, and plant remains, among other things, in an effort to determine the time and cause of the victim’s death, as well as any information that may lead the authorities to the culprit. Forensic Biology is the analysis of body fluids, stains and other bodily materials to help solve a crime.
