Throughout the past three decades, the criminal justice system has decidedly employed new technologies for the purposes of establishing guilt or innocence. Forensic science, with its synthesis of scientific methodology and investigative considerations of law enforcement, ushered in the development of DNA profiling and forever changed the process of crime scene investigation.This shift in focus also led to a shift in the individuals involved in investigation, producing the widespread formation of stand-alone crime scene units. Utilizing both civilian and sworn employees of a law enforcement agency, these units became responsible for the documentation, collection, and preservation of evidence that would …

In forensic casework analysis it is necessary to obtain genetic profiles from increasingly smaller amounts of biological material left behind by perpetrators of crime. The ability to obtain profiles from trace biological evidence is demonstrated with so-called ‘touch DNA evidence’ which is perceived to be the result of DNA obtained from shed skin cells transferred from donor to an object or person during physical contact. However, the current method of recovery of trace DNA involves cotton swabs or adhesive tape to sample an area of interest. This "blindswabbing" approach may result in the recovery of biological material from different individuals …
