Forensic sciences is the term given to an examination and investigation of a crime using scientific means. Forensic science is a fundamental instrument for the recognition or investigation of crime and the ruling of justice, depending on data and information about the evidence found at crime scene. The validity of those results relies on the knowledge, abilities, and experience of the forensic scientist attempting to get them. A forensic researcher must be equipped for incorporating learning and abilities in the examination, investigation, translation, reporting, and testimonial backing of evidence. Forensic examination of biological evidence depending on biotechnology strategies and methods is progressively important in criminal investigations.
Their job includes, but is not limited to, conducting interviews, locating missing persons and criminal suspects, examining records, writing detailed reports and occasionally making arrests. Police investigators and private investigators salaries differ, but the basic combined range is $26,920 - $128,690+. A Bachelor’s Degree with subjects of Government, History and Psychology is the minimum required education level. It is also required to have experience as a police officer for at least three to five years. (Detectives.)
By examining the DNA evidence obtained from the crime scene, the law enforcement officials can be able to identify the suspects (Kayser, 2017). Identifying the suspects will require the law enforcement officials to match samples of possible suspects with those obtained from the crime scene. A non-match could be a strong indicator that the suspect was not involved.
Abstract - Criminalisation is a social phenomenon, which has drastically increased in last few years. In order, to make the job of the investigating agencies easy, use of technology is important. Crime investigation analysis is a field where data mining plays a vital role in terms of predicting and analysing the criminals. In our paper, we have proposed an integrated model for physical crime as well as cybercrime investigation. Our approach makes use of data mining techniques for crime detection and criminal identification for physical crimes and digitised forensic tools for evaluating cybercrimes.
Evidence like this helps in proving that the suspect was there. If the cops take the suspect back to the crime scene after the arrest, it will affect the evidence of suspect’s presence there. That is because when the testimony is presented in the court, it may serve solely to prove that the suspect was taken there by the cops. VII.
The role of a criminal psychologist is not just to use their expertise to figure out the mind of a criminal, but it is also used for understanding, developing and improving the life of the people they deal with. When a person commits a crime that the police cannot fully understand or handle, they can call in the help of a criminal psychologist. Different methods of solving and understanding a situation can be used. Criminal psychologists are involved in many parts of the legal process, whether its interviews, assessments, therapy or prison life, they can have a huge input on a case.
This is very important especially interviewing those persons who are living in close proximity to where the crime has been committed. For example, the investigator should begin questioning persons who are living next door to the victim on what they have seen or heard. After he has gathered enough information from eyewitnesses he can then move on to questioning the suspect who in this case is the roommate. Finally, the investigator before he decides to interrogate the suspect who is found at the crime scene he must make sure that the requirements under the Miranda Law have been observed. The Investigator must see to it that the suspect has been informed of his right and that he has the right to remain silent and that he has the right to seek the service of his own Attorney.
Like other crime too, homicide crime is solved by going through several processes. They are receiving report, planning the investigation, interviewing victims and witnesses, examining the crime scene, arresting and interviewing suspects and last but not least, completing the report. Firstly, the complaint is reported to a responder. The first action taken by
Anyone that wants to become an Federal bureau Investigator agent needs experience with law enforcement before joining the FBI production.

An FBI needs a college degree and most of them choose to get a Bachelors degree in Criminal Justice.
The Department of Justice says, "States began passing laws requiring offenders convicted of certain offenses to provide DNA samples. " That DNA evidence can help convict someone of a crime and it helps to uncover more things about the crime itself. Investigators have been using forensic science to help them solve cases since before the 90 's, mostly fingerprints that were found at the crime scenes and on the victims (O 'Brien). DNA evidence has solved countless cases including ones that happened over a prolonged period of time because of the technological advancements there is
As we gone further along in history we can now detect DNA, DNA from dental, saliva, cameras, and facial sketches. “DNA databases have been raised using arguments from biomedical ethics; these databases are used in a complete Different context from other biomedical tools. Because they are used in the struggle against crime, the decision to create or store cannot be left by the individual. Genetic profile Instead, this decision is made by officials of society.” Annemie Patyn and Kris Dierickx Shows the pivotal role evidence has on solving crimes.
The assistant in the crime scene investigation has the role to assist the CSI with the measurements and finally the report may be revised by the same for any corrections if he thinks is required in the document. Carrying out a Complete Enquiry A detailed search is required at the crime scene as the next step of investigation. Each nook and corner of the location must be revisited by the CSI in order to get even the smallest piece of evidence, if any. Many crime scenes use an evidence vacuum in the scene for collecting any micro particle as evidence such as hair and fibers which may become a useful link to the culprit.
Anthropologist The main focal point of a forensic anthropologist is to process the crime scene, examine the victim’s remains, create a biological profile and testify in court. When a forensic anthropologist analyses the scene they have certain duties to perform, these include: conducting an onsite search for human remains, determining if any remains are human, set up a screening area, set up a staging area and preserve the scene by setting up grids. Anthropologists conduct an onsite search because it can give them an idea of how the remains have been scattered, this allows them to revise the search method being used so the remains stay intact and new evidence can be found.
