Preface
“If the law has made you a witness, remain a man of science. You have
no victim to avenge, no guilty or innocent person to convict or save—
you must bear testimony within the limits of science.”
Dr. P. C. H. Brouardel
19th-century French medico-legalist
The media abound with references to and programs about forensic sci-
ence. No mystery story seems complete without a reference to DNA evidence
or a trip to the laboratory for DNA analysis. Sometimes, the main characters
are forensic scientists. There are things to be learned from these media hap-
penings and truth does enter into the plots, making them fascinating to watch
and read. From such television shows as Quincy in the 1970s to CSI: New
York in 2004, and from the motion picture The Bone Collector to the recent
television show Forensic Files, forensic science has perennially shown the
power to entertain.
These media portrayals also educate us, but often, this “education” proves
to be more fantasy than reality. The Forensic Laboratory Handbook: Proce-
dures and Practice was written for the purpose of separating fiction from real-
ity by demonstrating the real-life practices of forensic laboratories.
The work performed by forensic scientists in the field, forensic laborato-
ries, medical examiners offices, and private companies is often critical to the
proper functioning of the justice system and regulatory bodies. Forensic analysis
has provided fresh information in “cold cases,” served to identify the last
descendants of the Russian imperial family, and exonerated the wrongfully
convicted. This is not to say that the original analyses were flawed, but rather
that new technology provides more and better information.
Where would society be without the analysis and comparison of finger-
prints, bullets, DNA, and handwriting? The identification of drugs, flammables,
bones, and explosives is often central to a case. Newer applications of tech-
nologies are used in investigating cyber crime, bite marks, and the reconstruc-
tion of a crime scene or a face from a skull.

vi Preface
With such an important place in the justice system, the integrity of scien-
tific information is crucial. The ethical analysis of evidence must be a given
constant. The exchange of new technology and open access to scientific infor-
mation assists others in understanding, and possibly implementing, new pro-
cedures.
Although the job of a forensic scientist is important and one of the most
satisfying of career choices, as with every other profession, the work can some-
times seem mundane and repetitious. Although many media programs may
portray some aspects of the profession correctly, they also tend to glamorize
the jobs. In the media, many separate jobs are rolled into one so that the story
flows better and the crime is solved in the time allowed. Cases that in reality
would take months or even years to solve are wrapped up in 42 minutes
on television. Not mentioned is the time needed to describe and prepare the
evidence for analysis, the expertise needed to interpret the results, the time
spent writing the scientific report, and the time spent in court giving expert
testimony. Add the time spent educating law enforcement, attorneys, and
judges, and the time spent in training to ensure that the scientist is on the
cutting edge with specialized skills and you can well appreciate the demands
placed on forensic professionals.
The forensic scientists who wrote the chapters in The Forensic Labora-
tory Handbook: Procedures and Practiceare real—they actually do what they
write about. Each is an unsung hero, a seeker of truth, a dedicated scientist.
They will tell you how it is in a real forensic laboratory, and it will be a fasci-
nating story.
