Abstract :
With an increase in criminal activities, a large
number of crime cases are reported every day. These
violent crimes are usually suicidal, homicidal, or accidental
in nature. In forensics investigations, blood is the most
significant and valuable biological evidence, which is found
very frequently at crime scene. The main motive of the
collection of biological samples from the crime scenes is to
get the genetic information from collected samples and use
that information for the identification of the suspect. A
DNA profile indicates the person’s identity and the pattern
of the streaks reveals the crime scene position, which
means both DNA profiling, and bloodstain patterns serve
as a significant tool for the identification of the
perpetrator. The blood found at the crime scene in the
form either blood pool or stain, needs to be collected,
preserved, and analyzed by the examiner on the spot or in
the laboratory. The dried bloodstains can give an
indication of the relative age of a trauma and timing of its
occurrence , which can be extremely helpful to
investigators in determining whether the stain was related
to that crime scene or not. Numerous researchers gave
their contribution in the development of a plethora of
methods for the determinations of age of dried bloodstains.
In the present study, an attempt has been made to review
all those conventional and modern techniques used by
various scientists to estimate the age of the bloodstains.
