Book excerpt: Adult temporary tattoos have become more popular, yet there is very little research on them, especially regarding their use in forensics. This poses a problem because forensic investigators may not be able to distinguish a temporary tattoo from a real tattoo, possibly hindering their investigation. In this study, various types of adult temporary tattoos were examined and analyzed in attempts to identify and distinguish them, both from each other and from permanent tattoos. Infrared spectroscopy, specifically attenuated total reflection (ATR), proved to be more useful than ultra-violet visible light spectroscopy in terms of analyzing the samples. The natural adult temporary tattoo samples, henna and jagua, were easily distinguished from each other based on their ATR spectra. When analyzing the transferrable picture tattoo samples, it became evident that the adhesives overwhelmed the sample, and that different brands used different adhesives. The transferrable picture tattoos may also be distinguished from permanent tattoos based on the presence of a printing pattern, which can be visualized with microscopy. This study contributes to the field by yielding knowledge of adult temporary tattoos not previously known, so that perhaps in the future the knowledge may be used to aid in casework.

Book excerpt: While children's temporary tattoos have been produced since the 20th century, there are few scientific studies that have evaluated their physical and chemical characteristics. Therefore, this thesis is a preliminary study done to evaluate the composition of children's temporary tattoos and consider the importance of such traces in a forensic content. Colored regions in children's temporary tattoos, such as red, pink, yellow and orange, were found to fluoresce with the use of an alternative light source while the use of microscopy led to the identification of different printing patterns between temporary tattoos. However, limitations in the ability to determine the composition of the children's temporary tattoos using ultraviolet-visible (UV-Vis) spectroscopy and infrared (IR) spectroscopy methods were encountered due to the instability of the dyes in solvents for extraction when exposed for long periods of time and the presence of the colorless adhesive.

Book Synopsis Strengthening Forensic Science in the United States by : National Research Council

Download or read book Strengthening Forensic Science in the United States written by National Research Council. This book was released on 2009-07-29. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
