    Abstract

    In the process of fingerprint development Physical Developer has been largely the method of choice on porous surfaces after coming into contact with wet environments. It is only recently that a new technique has been identified which could replace this standard technique. This study aims to build on previous research and expand knowledge regarding the technique. The study built on previous research and compared Physical Developer to Oil Red O, testing both on four paper types, while being placed in three different water types and an accelerant for various amounts of time. Marks were placed with both heavily 'loaded' sebaceous fingers and 'normal' un-washed fingers. Results show that Oil Red O consistently produced clearer more detailed marks from the 'loaded' fingers, but neither technique proved to work better on the 'normal' marks. Neither technique developed any prints from the accelerant.
