Extraction and Profiling of Wearer DNA from Different Types of Glove Surfaces in Bank Robbery

DNA fingerprinting and profiling are emerging as important and authentic tools for criminal investigations. The “Touch DNA” or “Trace DNA” is the manifestation of this at the miniature level. In burglary-related crimes, multiple tools have been used; therefore, profiling and exact matching with the accused have become problematic. In addition, the surface of the tool is a deciding factor for DNA accumulation. . In this article, we used three pairs of gloves made up of different materials (latex and denim cloths). The amount of DNA obtained from gloves A and B (latex) were 1.877 ng/µl and 0.91 ng/µl, respectively. However, in the case of glove C, we demonstrated that the extraction of DNA from the denim cloth was difficult; therefore, we chose a single fiber thread for this purpose. For a single thread, the quantity obtained was 0.06 ng/µl even after 520 days of incidence.
