Streszczenie
A number of methods have been reported in the literature for the development of latent fingermarks on different substrates. This study was aimed to check the potential of red sandalwood (Petrocarpus santalinus) powder which is easily available and non-toxic for the development of latent fingermarks. In this investigation latent fingermarks on seven different substrates which are commonly encountered in the crime scenario namely wooden switch board, plastic on/off switch, paper, glass, laptop, plastic container, and aluminum foil along with development of aged fingermarks deposited for a varied period up to two weeks on glass substrate was carried out using naturally occurring red sandalwood powder. It was observed from the study that due to good contrast of red color latent fingermarks are developed successfully on all the mentioned substrates and red sandalwood powder has potential to develop latent fingermarks on glass substrate aged up to thirteen days.
