Forensic science utilizes scientific principles to support or negate theories surrounding physical evidence found at a crime scene. As such, forensic scientists analyze evidence gathered or received from crime scenes and present their findings based the results of their analyses. A forensic science job description may appear distinctly different depending on the area of forensic science being practiced. This is because forensic science is a rather broad field and thus encompasses a number of specialties, all of which are rooted in the natural sciences.

2. Forensic science
• It is the application
of science to criminal and civil laws, during criminal
investigation, as governed by the legal standards
of admissible evidence and criminal procedure.
• Study of evidence discovered at a crime scene and
used in a court of law

3. What a forensic investigator do?
A forensic expert/scientist :
Collect

• Collection of evidence from crime scene
• For future reference
• To connect links and solve the crime

4. Services provided by forensic scientist

evidence to
laboratory
In the laboratory
• Examination of
evidence

8. Specialized training
The duties, assignments, and procedures vary from
departments and agencies regarding the investigators
or technicians. Therefore the job description may vary
depending on geographic locations.

9. Basic Services Provided by Forensic
Science Laboratories
• Physical science unit
• Biology unit
• Firearms unit
• Document examination unit
• Photography unit
• Toxicology unit

10. Optional Services Provided by
Forensic Science Laboratories
• Polygraph unit
• Voiceprint analysis unit
• Crime-scene investigation unit
• Forensic odontology
• Forensic computer and digital analysis

11. Responsibilities Of Forensic Scientists Include:
• Carrying out laboratory examinations and analyses submitted by law
enforcement agencies and medical examiners
• Serving as expert witnesses in a court of law
• Carrying out tests using scientific techniques, such as infrared spectroscopy,
mass spectrometry, and scanning electron microscopy
• Ensuring all laboratory protocols and regulations are followed
• Inputting data into computer programs and utilizing relevant computer
database information
• Overseeing the maintenance and calibration of laboratory equipment
• Preparing written reports based on evidence analysis
• Coordinating the activities related to crime scene collection, preservation,
and transportation
• Serving as a liaison between the forensic laboratory and crime scene
investigators
• Developing, maintaining and updating work quality standards, standard
operating procedures, and similar methods and procedures
• Coordinating work with other members of the forensic team and with
outside agencies

12. Forensic Scientist Skills and Education
• Although the job duties of forensic
scientists will vary according to their
discipline or specialty, they must possess
similar skills, which include being able to
adequately exhibit:
• Critical-thinking skills
• Problem-solving skills
• Verbal and written skills
• Deductive reasoning
• highly perceptive and detail-oriented
• able to spend extended periods
conducting meticulous, often painstaking,
work.

15. CURRENT AND EMERGING ISSUES FOR
FORENSIC SCIENCE SERVICE PROVISION
• Advances in technology
• Forensic intelligence
• Serious and organised crime
• Alcohol, illicit drugs and misuse of pharmaceuticals
• Family and domestic violence
• Firearms

16. CONCLUSION
• The strength of Forensic Science principles lies in their
application in the field to solve crime.
• Greater the use of forensic principles i.e. scientific methods
of gathering and examining information, better will be the
chances to solve the crime, reconstruct the modus operandi
and catch the perpetrators.
• Only with the complete willingness of field officers handling
evidence at the crime scene, can the new forensic
techniques and methods prove to be helpful.
• The journey from ‘crimes reported’ to ‘crimes solved’ is
through the path of Forensic Science.
