Detectives and police officers collect evidence much the same way as they do today, but there is one main difference. Science is not used. Due to the lack of scientific analysis, there would not be a lot of useful evidence. Without the use of science, criminals could not be convicted of their crimes, ranging from common theft to a homicidal rampage, unless there was an eyewitness present at the crime scene when the crime occurred.
What is Forensic Science? Forensic Science deals with the application of the knowledge and methodology of various disciplines of science to legal matters.
It involves the use of multiple disciplines such as physics, chemistry, biology, computer science and engineering for evidence analysis.
For instance, physics is used to understand the pattern of a blood spatter, biology to establish the source of an unidentified suspect and chemistry to determine the composition of drugs.
Thus, the role of forensic science in criminal justice and the legal system is highly critical but is often underrated. Apart from fingerprint analysis, DNA profiling is the other commonly used forensic technique in criminal investigations.
DNA being as unique to an individual as fingerprints, help forensic professionals identify or confirm an unidentified person, or to eliminate suspects from a list of accused. The biological evidence most commonly used for DNA profiling include blood, saliva, semen, skin, urine, and hair. However, DNA fingerprints are usually never used as the single piece of evidence in the court of law.
Forensic odontology helps in the identification of victims when the body is left in an unrecognizable state.
This is achieved through an examination of their teeth, the alignment, and overall structure of the mouth. Forensic dentists or odontologists aid in the comparative identification of a person by examining the development and anatomy of the teeth including any restorative dental corrections such as filling.
It is often applied to criminal investigations for bite mark analysis. Chemicals that are legally recognized as having the potential for abuse are called controlled substances. The ability to detect and identify such controlled substances plays a crucial role in aiding law enforcement agencies in their fight against drug abuse and drug-based violence.
Forensic Toxicology involves analysis of biological samples to check for the presence of toxins and drugs. This branch of forensic science is of prime importance in road accidents, poisoning, sexual violence etc.
The toxicology reports furnish key information about the nature of substances present in an individual pertaining to an incidence. It also determines whether the quantity of substances are normal as per a therapeutic dosage or exceed the permissible level.
Since newer variants of drugs are developed each day, this branch of forensic science is ever-evolving and demands up-to-date approach.
This deals with the examination of compromised human remains or skeletons to help determine the age, height, gender, and ancestry. It also helps establish the time since death by identifying and examining injuries, if any.Criminal Investigation has proven a lot of cases to go on investigation by forensic investigators, and it has put a lot of crimes behind bars.
As the television criminal shows have proven a lot of deaths to be solved. Journal of Forensic Sciences & Criminal Investigation (JFSCI) This is one of the open access journals that is determined to publish the most complete and reliable source of information on discoveries and current developments related to forensic and criminal science department.
Role of Forensic Science in Criminal Investigations Forensic science is that piece without which the puzzle of a criminal investigation is incomplete. Without the application of forensic science, criminals can never be convicted unless an eyewitness is present.
This field of science dealing with criminal investigation is known as forensic science, which roughly means the application of science to law (Microsoft ). Forensic science can be used to determine many things from the evidence when it is collected properly without any contamination.
