The method is conducted by placing fingerprints on 10 different indoor plant leaves that are commonly seen in places of Northern Kerala . The powder dusting method was used for the development of latent fingerprints. The persistence of latent fingerprints was also analyzed by taking time interval as a criterion. The method being used is by placing fingerprints on different leaves of the same plant and developing them at different time intervals. This study showed that a forensic investigator is able to identify and develop the latent fingerprints on indoor plants.
