Trace Evidence Examination
Pamela M. Woods · 2005
The collection and examination of trace evidence has largely developed due to the theory of Edmund Locard. His proposed theory, Locard’s Exchange Principle, involves the transfer of evidence from one object or person to another object or person.1 These ideas have become the basis for crime scene investigation. Popular culture is now more familiar with the transfer of evidence due to a surge in popularity of shows based on crime scene investigation. However, these television shows seem to focus audiences on the drama and glamor of the investigative process. Talk to those who work in the field of forensic science for a true opinion on crime scene investigation and the tedious task of examining the evidence. Although much attention is focused on the profession of Forensic Science, the public may be apt to have unreal expectations when it comes to the investigative process. Sensationalized television dramas are capable of solving a complicated homicide in one hour. The story line swiftly moves from a bloody crime scene to the hi-tech scientific examination of evidence and finally to a firm conclusion. A nice pat on the back for the forensic investigator and the case is solved . . . next case, please.
