    Abstract

    Detection of fingerprint evidence on black electrical tape has often been a frustrating experience for many examiners because of the very nature of the substrate.

    The tape, which is frequently found on numerous crime-related exhibits, particularly weapons, requires a number of steps to render any evidence visible, including separate processing techniques for each of the surfaces.

    Basic fuchsin (rosaniline chloride) is a fluorescent reagent which provides a “one-step” alternate processing technique.

    Fingerprints of different ages and from a variety of donors were processed and the results, as well as the comparison of this process with the established techniques of gentian violet (or crystal violet) and cyanoacrylate/rhodamine 6G, are discussed.
