    Area of Science:

    • Forensic Science
    • Biochemistry
    • Dermatology

    Background:

    • Mummified finger preservation poses challenges for fingerprint retrieval.
    • Previous softening methods were often destructive or ineffective.

    Purpose of the Study:

    • To introduce a novel, non-destructive technique for softening mummified fingers.
    • To enable the successful recovery of usable fingerprints from mummified remains.

    Main Methods:

    • A simple technique utilizing disodium ethylenediamine tetraacetic acid (EDTA) in a detergent solution.
    • The solution was adjusted to a specific pH of 7.5.
    • The method was applied over a ten-year period.

    Main Results:

    • Achieved satisfactory to good quality fingerprints from mummified fingers.
    • The technique proved successful in every attempted case over the decade.
    • Demonstrated a non-destructive approach to fingerprint recovery.

    Conclusions:

    • The EDTA-based detergent solution is a highly effective method for softening mummified fingers.
    • This technique offers a reliable and non-destructive solution for forensic fingerprint analysis.
    • The method has a proven track record of success in practical application.
