Abstract

Abstract:
The purpose of this paper is to present a case study of a crime committed in a remote area of Pakistan
where a woman was found dead and her death was reported as a suicide. Investigation agency collected
the data including the pictures from the crime scene. These pictures were sent to crime scene unit for
their recommendations. Forensic experts studied and analyzed these pictures and by applying the
techniques of Bloodstain Pattern Analysis (BPA). As blood behaves according to certain scientific
principles, trained bloodstain pattern analysts can examine the blood evidence left behind and draw
conclusions as to how the blood may have been shed. It is done by examining the distribution, location,
shape and size of the bloodstains and it helps in determining about what did or did not happen. Because
blood behaves according to certain scientific principles, trained bloodstain pattern analysts can examine
the blood evidence left behind [and draw conclusions as to how the blood may have been shed]. BPA
provides information not only about what happened, but just as importantly, what could not have
happened.A detailed analysis gave enough evidence to the experts that the submitted case was not a suicide rather it
was a case of a homicide. The paper will attempt to study the observations of experts while analyzing the
bloodstain pattern submitted to them and the conclusions they subsequently drawn, leading towards a
clear evidence of a murder case.
