CFC Forensic Science Principles & Investigative Methods

Question 1

What is the primary goal of forensic science?

Accepted Answer

To apply scientific techniques to solve crimes

Answer

The primary goal of forensic science is to apply scientific principles and methods to legal matters, predominantly in criminal and civil investigations. Forensic scientists analyze physical evidence found at crime scenes or related to incidents. This objective analysis provides crucial data and insights to help investigators understand events, identify individuals, and present evidence in court.

Question 2

Which evidence type is most commonly analyzed in forensic labs?

Accepted Answer

Biological materials such as blood and hair

Answer

Biological materials, such as blood, hair, saliva, and other bodily fluids, are among the most commonly analyzed evidence types in forensic laboratories. These materials are rich sources of DNA, which can be used to uniquely identify individuals, link suspects to crime scenes, or exclude innocent parties. The power of DNA analysis makes biological evidence incredibly valuable in criminal investigations.

Question 3

What is the chain of custody in forensic investigations?

Accepted Answer

A documented process tracking the handling of evidence

Answer

The chain of custody in forensic investigations is a meticulously documented process that tracks the handling, transfer, and analysis of physical evidence from the moment it is collected until it is presented in court. This unbroken record ensures the integrity and authenticity of the evidence. Maintaining a strict chain of custody is crucial for preventing tampering, preserving the evidence's probative value, and ensuring its admissibility in legal proceedings.

Question 4

Why is maintaining the integrity of evidence crucial?

Accepted Answer

To prevent accusations of mishandling and uphold court admissibility

Answer

Maintaining the integrity of evidence is crucial to ensure its reliability and admissibility in a court of law. If evidence is mishandled, contaminated, or altered, its authenticity can be challenged, potentially leading to its exclusion from trial. Proper preservation and documentation prevent accusations of mishandling, uphold the evidence's scientific validity, and strengthen the prosecution's or defense's case.

Question 5

Which field of forensic science involves fingerprint identification?

Accepted Answer

Dactyloscopy

Answer

Dactyloscopy is the specialized field of forensic science dedicated to the study, analysis, and identification of fingerprints. It involves comparing the unique patterns of friction ridges found on fingers, palms, and soles. Since these patterns are unique to each individual and remain unchanged throughout life, dactyloscopy is a highly reliable method for personal identification in criminal investigations.
