Abstract
Violent bloodletting crimes often result
in the presence of impact bloodstain
patterns on walls and other surfaces
found within the crime scene. These
patterns may be fully developed and
clearly identifiable, other times they
may be subtle and not easily detected.
The collection of sufficient spatter stains
can be critical to an accurate analysis.
The bloodstain pattern analyst is faced
with many challenges relating to the
documentation of spatter stains within
the crime scene. Subsequent analysis of
the spatter stains provide significant
information regarding the location of
the blood source at the time blows were
struck. Advances in digital imaging and
bloodstain computer analysis software
have provided powerful tools in area of
origin determinations. These advances
can assist in more complete analysis as
well as reduce time extended in the
scene determining which stains to document
and collect. These advances can
also provide methods which could be
used by trained forensic personnel to
effectively document and collect spatter
stains for subsequent off-scene analysis
by a bloodstain pattern analyst who is
unavailable for scene attendance.
