| dc.description.abstract | Biological samples are used in forensic medicine to identify individuals, establish the
time of death, determine the cause of death, and other reasons regarding the crime.
This qualitative research involves both primary and secondary sources and focuses on
the criminal investigation procedure based on the utilization of biological samples which
involves a variety of techniques, including fingerprinting, Genetics profiling, serology,
and other conventional methods. These techniques rely on meticulous examination and
comparison to establish connections between the evidence and potential perpetrators.
Biological evidence can provide investigators with valuable information about the perpe trators of crimes and help solve cases that would otherwise be cold. In the Sri Lankan
context, the usage of biological sample testing is a common practice. However, in the
21st century, technological and scientific advancement has led to the usage of novel
methods in the identification of the perpetrator which has made biological testing more
flexible and prudent, but this is not fully grasped by the country. Furthermore, the law
enforcement authority plays a vital role in the investigation, whereby, they are responsible
for securing the scene, preserving evidence, collecting fingerprints, and other physical
evidence. Biological samples have the potential to be a valuable resource for a criminal
investigation. However, there are a number of challenges that need to be addressed as
well. If these challenges are well addressed, biological samples can be more beneficial in
identifying perpetrators and aiding in the well-being of the people of Sri Lanka. | en_US |
