ABSTRACT

Criminals have increasing counter-detection awareness. Some of them evade monitoring by wearing masks. Moreover, the outbreak of COVID-19 pandemic makes medical surgical masks more commonly used. In some criminal crime scenes, the public security organ often extracts DNA information from the facial mask on the scene, ignoring development of its latent fingerprints. In this paper, the sweat latent fingerprints on medical surgical masks were successfully developed by "502" glue fumigation. The BBD fluorescent staining was used to enhance the development effect, making it possible to develop the sweat latent fingerprints on the outer layer of medical surgical masks, which provides reference ideas for solving the problems in public security work.
