Wearer DNA is the deposit of epithelial cells on clothing worn by an individual. Detection of the last individual to handle or wear an item is often an important and desirable determination in forensic science. The most commonly used collection methods for wearer DNA include swabbing and scraping. These often result in mixture profiles. Recently, adhesives have been introduced as a possible reliable method for the collection of biological evidence. The goal of the research was to compare the current collection methods of swabbing and scraping with a gel film called Gel-Pak ‘0’ which shares similar properties with adhesives. Gel-Pak …

Confirmation Bias: The Pitfall Of Forensic Science, Scott Moser
Themis: Research Journal of Justice Studies and Forensic Science
As it stands, forensic science and its practitioners are held in high regard in criminal court proceedings due to their ability to discover irrefutable facts that would otherwise go unnoticed. Nevertheless, forensic scientists can fall victim to natural logical fallacies. More specifically, confirmation bias is “a proclivity to search for or interpret additional information to confirm beliefs and to steer clear of information that may disagree with those prior beliefs” (Budlowe et al., 2009, p. 803).
