Bloodstain Pattern Analysis
by Tom Bevel, Ross M. Gardner
Used properly, bloodstain pattern analysis helps establish events associated with
violent crimes. As such, it is a critical bridge between forensics and the ultimate goal
of forensics, defining an accurate crime reconstruction. The second edition of this
bestselling book is thoroughly updated to employ the latest protocols, including the
application of scientific method, the use of flow charts, and the inter-relationship
of crime scene analysis to criminal profiling. It provides more illustrations, including
color photographs, and explains the use of computer programs to create demonstrative
evidence for court. Bloodstain Pattern Analysis aids forensic scientists, investigators,
and attorneys in understanding violent crime scenes. It provides quick and accurate
information to help the reader understand blood stain pattern information.

Population genetics in the forensic DNA debate
by B S Weir
The use of matching variable number of tandem repeat (VNTR) profiles to link
suspects with crimes is potentially very powerful, but it has been quite controversial.
Initial debate over laboratory procedures has largely given way to debate over the
statistical and population genetic issues involved in calculating the frequency of a
profile for a random member of a population. This frequency is used to weight the
evidence of a match between suspect and crime scene material when the suspect denies
responsibility for that material. A recent report from the National Research Council,
intended to put to rest some of the issues, has instead raised further debate by
advocating a procedure based on maximum frequencies of profile components over
several different populations.
