Annotation: This study tested various variables, including time and temperature, to enhance the process of lifting fingerprints from skin using a magnetic powder and lifting the prints with silicone.
Abstract: The study was conducted in two parts; testing fingerprint powders most successful at developing fingerprints on skin, and testing casting materials to determine which were most productive in lifting the prints. The second part of the study focused on time intervals from placement and lifting, and body temperature at which a fingerprint could be developed. Data were collected through testing the author’s fingerprints on the skin of fetal pigs, which is similar to human epidermis. Black magnetic powder and "Mastercraft" silicone were determined to produce the best results. Part two of the study revealed that temperature plays an important role in the successful collection of prints, with greatest success at room temperature (21-22 C), and within 48 hours of placement of the prints.
